text: In many developmental systems, cells differentiate into a tissue by reading
out morphogen concentration fields, a process fundamentally limited by noise.
How much can the precision of this process be improved by nonlocal information,
e.g., via cell-cell communication? Using a Bayes-optimal framework, we show that
positional inference depends crucially on morphogen spatial correlations and on
the "structural prior" that encodes the geometry of the cellular lattice performing
the readout, thereby determining what a cell can reliably assume about the position
of its neighbors when interpreting nonlocal morphogen signals. We derive upper
bounds on positional information gain due to nonlocal readout and identify signal
processing algorithms that approximate optimal positional inference, as well as
simple chemical reaction schemes which implement such algorithms. Our theory suggests
that correlational information can be exploited to significantly enhance developmental
precision.

text: RNA polymerase II (Pol II) must be assembled in the cytoplasm before it enters
the nucleus, where it transcribes protein-coding genes. Although transcription
by Pol II is intensively studied, how this central multi-subunit enzyme is made
and the role of dedicated assembly factors remains unclear. Here, we report the
integrative structural analysis of a native human Pol II from the cytoplasm captured
near the end of biogenesis. The complex contains Gdown1 and three biogenesis factors
– RPAP2 and the critical small GTPases GPN1 and GPN3. Cryo-EM analysis of the
complex reveals how Gdown1 and RPAP2 associate with Pol II and prevent the premature
association of transcription factors. Further biochemical and cryo-EM analysis
reveals how RPAP2 tethers GPN1–GPN3 to the complex and how the assembly of the
RPAP2–GPN1–GPN3 complex is controlled by GTP hydrolysis. The combined results
uncover a network of interactions that chaperone cytoplasmic Pol II to prevent
aberrant interactions, reveal a molecular switch regulating biogenesis factor
association, and suggest a general mechanism for the action of GPN-loop GTPase
family of enzymes.

text: The advantageous characteristics attributed to the 19F nucleus have made it
a popular target for nuclear magnetic resonance (NMR) once again in recent years.
Aside from solution NMR, an increasing number of studies have been conducted applying
solid-state magic-angle spinning (MAS) NMR to fluorine-labelled samples. Here,
the high chemical shift anisotropy and strong dipolar couplings can be utilised
to get structural insights into proteins and measure long distances. Despite increasing
popularity and promising benefits, the sensitivity of biomolecular 19F MAS NMR
often suffers from slow longitudinal T1 relaxation and therefore long recycle
delays. In this work, we expand paramagnetic doping, an approach commonly used
to reduce proton T1 relaxation times, to 19F-labelled biological samples. We study
the effect of Gd(DTPA) and Gd(DTPA-BMA) on 19F T1 and T2, and 13C T1 and T2 relaxation
in a [5-19F13C]-tryptophan-labelled protein via 19F-detected MAS NMR experiments.
The observed paramagnetic relaxation enhancement substantially reduces measurement
times of 19F MAS NMR experiments without compromising resolution. Additionally,
we report the chemical shift assignments of all four fluorotryptophan signals
in the 12×39 kDa-large protein TET2 using a mutagenesis approach.

text: We prove a mesoscopic central limit theorem for linear eigenvalue statistics
of correlated Hermitian random matrices. The class considered here includes Wigner
and Wigner-type matrices, as well as models whose entry correlations decay polynomially
in the distance between index pairs. The proof combines a multivariate cumulant
expansion with multi-resolvent local laws and a detailed analysis of the resulting
variance kernel on the operator-level.

text: "We present a systematic study of the environments of 25 luminous quasars
at z > 6.5 from the ASPIRE program.\r\nUsing JWST/NIRCam wide-field slitless spectroscopy
data, we identified 487 galaxies at 5.3 ≲ z ≲ 7.0 exhibiting\r\n[O III] emission.
Among these, 122 [O III] emitters lie within |Δvlos| < 1000 km s\r\n−1 of the
quasars, corresponding\r\nto a ∼9.4-fold enhancement relative to the average galaxy
density at other redshifts. Furthermore, we identified 16\r\n[C II]-emitting galaxies
at the quasar redshifts from Atacama Large Millimeter/submillimeter Array (ALMA)
mosaic observations. A cross-correlation function analysis between quasars and
[O III]+[C II] emitters yields a\r\ncross-correlation length of r 8.68 h cMpc
0\r\nQG\r\n0.55 = +0.51 1\r\nand an autocorrelation of r 15.76 h cMpc 0\r\nQQ\r\n2.70
= +2.48 1 ,\r\nindicating that z ∼ 7 quasars reside in dark matter halos with\r\nMhalo
1012.27 0.26 M 0.21\r\n= +\r\nand have a quasar lifetime of\r\ntQ 10 yr 7.05 1.01\r\n0.95\r\n=
+\r\n. Notably, the number of [O III]-emitting galaxies at quasar redshifts varies
significantly from\r\nfield to field, ranging from 0 to 20, highlighting a diverse
quasar environment. Remarkably, seven quasars trace\r\nsignificant galaxy overdensities
(i.e., protoclusters), with δgal > 5 within a volume of V ∼ 500 cMpc3\r\n. We
also\r\nfind that |Δvlos| increases rapidly toward smaller galaxy–quasar separations
in protocluster fields, consistent with\r\ngalaxy kinematics around extremely
massive halos in cosmological simulations. By combining JWST and ALMA\r\ndata,
we reveal the complex and diverse environments of these early quasars, providing
robust evidence that the\r\nearliest luminous quasars are effective tracers of
galaxy overdensities, albeit with substantial field-to-field\r\nvariation."

text: Finding the first generation of (Population III or Pop III) stars is one of
the most ambitious and exciting challenges of astrophysics. JWST opened concrete
prospects for their detection during the Epoch of Reionization, where increasing
evidence suggests that residual Pop III formation may persist, even within pristine
pockets of high-mass halos, due to inhomogeneous enrichment. However, the identification
of Pop III stars within globally enriched environments will be challenging. We
investigate the detectability of a subdominant Pop III component in/around massive
(M⋆ ≳ 10^9 M⊙) galaxies at z ≈ 6.5–9 from the dustyGadget cosmological simulation
suite, and the confusion arising from second-generation (Pop II) stars in their
surroundings. We find that young (≲1 Myr), massive (MIII ∼ 6 × 10^5 M⊙) Pop III
clusters forming within these galaxy environments are responsible for strong HeII1640
line emission (LHeII1640 ≳ 10^41 erg ^s−1), which would be detectable with ≈10(50)
hr of medium-resolution observations with NIRSpec/IFU at z ≈ 6(10). These bright
luminosities cannot be produced by standard Pop II populations alone. On the other
hand, the dominant Pop II component within massive “hybrid” Pop III hosts powers
strong metal line emission (L[OIII]5007 ≳ 10^42 erg s^−1), indicating that the
detection of metal lines alone cannot exclude the presence of Pop IIIs in high-z
galaxy environments. We further discuss candidate selection strategies based on
Lyα, Hα, and Hβ emission, and how spatially resolved observations may enable the
detection of isolated, pristine pockets in the outskirts of massive halos.

text: The high-redshift progenitors of present-day galaxy clusters are believed
to substantially contribute to the global star formation rate density and drive
the large-scale reionisation of the Universe. Here we present a blind and unbiased
search for and characterisation of galaxy overdensities during the reionisation
epoch at redshifts z ∼ 5.5 − 7 based on rest-frame optical JWST/NIRCam grism spectroscopy
of the Abell 2744 lensing field as part of the JWST All the Little Things (ALT)
survey. Using a physically motivated, cosmological inference friends-of-friends
(FoF) algorithm, we identified six galaxy overdensities, including five robust
systems at z = 5.66–6.77. They are all characterised by total halo masses of Mhalo ≳ 1011 M⊙,
inferred from a range of proxies. We find that the galaxy members in these overdense
environments are on average less massive though equally metal-rich, and generally
comprised of younger stellar populations, as indicated by their bluer spectral
slopes and less prominent Balmer breaks compared to field galaxies at similar
redshifts. Further, we use this novel rest-frame optical selection of galaxy proto-clusters
to infer the fraction and 3D distribution of strong Lyman-α emitters (LAEs) and
damped Lyman-α absorbers (DLAs) in the overdensity environments. We find that
two out of the six galaxy overdensities have excess H I absorption compared to
the field average, while the other four are consistent within their large scatter
in density. These results present the first direct observational constraints on
the tomography of the dense, neutral gas reservoirs in large-scale galaxy overdensities
at z > 5 and highlight the limitations of pre-JWST searches for reionisation-era
galaxy overdensities relying on the detection of strong LAEs alone.

text: Causal optimal transport and adapted Wasserstein distance have applications
in different fields from optimization to mathematical finance and machine learning.
The goal of this article is to provide equivalent formulations of these concepts
in classic probabilistic language. In particular, we prove a Skorokhod representation
theorem for adapted weak convergence, reformulate the equivalence of stochastic
processes using Markovian lifts, and give an expression for the adapted Wasserstein
distance based on representing processes on a common stochastic basis.

text: Neurons acquire polarity by specifying one neurite as the axon, whereas the
others become dendrites. But how this fundamental asymmetry is established remains
unclear1. Neuronal polarization has been thought to rely primarily on growth cones
that sense external cues2. Here we show that growth cones alone do not direct
this process and that the soma acts as a central organizer of neuronal polarization.
Using live imaging and genetic loss-of-function approaches in vivo, combined with
optogenetic control and local cytoskeletal perturbations in cultured neurons,
we uncover a soma-initiated oscillatory program that primes axon selection. Periodic
actin branching that depends on the actin-related protein 2/3 (ARP2/3) complex
at the soma remodels a global actomyosin network, thereby generating an actin
wave that retracts neurites before propagating into a single neurite tip. Exposure
to this wave relaxes local actomyosin contractility, which drives a transient
microtubule-based protrusion and biases this neurite towards axon fate. As the
cell exits this oscillatory stage, this neurite can overcome global inhibition
and extend independently of ARP2/3, whereas actomyosin activity suppresses axon
formation in the remaining neurites so that they subsequently become dendrites.
This soma-driven mechanism ensures the emergence of a single axon independent
of environmental cues and underpins the unidirectional information flow in neuronal
circuits.

text: "This thesis studies spectral rigidity and nonrigidity phenomena in dynamical
systems. The central question is whether a dynamical system can be determined,
up to a natural conjugacy, from its spectrum. We consider three related spectra:
the length spectrum, the action spectrum, and the Lyapunov spectrum.\r\n\r\nThe
first part of the thesis concerns Liouville metrics on the two-dimensional torus.
It is a long-standing folklore conjecture that Liouville metrics are the only
integrable metrics on the torus. We prove a length-spectral rigidity result for
linear conformal deformations of Liouville metrics by exploiting the dynamical
properties of the rational tori -- analogues of the resonant convex caustics in
billiards. We also establish a complementary classification result showing that
marked-length-isospectral Liouville metrics are characterized by rearrangements
of the one-dimensional functions appearing in their conformal factors, generalizing
a theorem of Abbondandolo-Mazzucchelli. In particular, the second result gives
nonrigidity examples within the class of Liouville metrics.\r\n\r\nThe second
part of the thesis studies the standard map from the viewpoint of action and Lyapunov
spectra. We construct nontrivial deformations of the standard map which preserve
the symplectic actions (respectively, the Lyapunov exponents) of infinitely many
periodic orbits accumulating on an invariant curve. The proof combines a resonant
normal form construction with Picard iteration schemes to obtain a sequence of
periodic orbits accumulating on an invariant curve with a Liouville rotation number.
Within the resonant normal forms we capture the dependence of these periodic orbits
on the resonant Fourier coefficients of the dynamics on the invariant curve and,
using the contraction mapping principle, obtain a suitable deformation achieving
the prescribed spectral data associated with this sequence of orbits. The result
can be viewed as a symplectic twist-map analogue of a length-spectral nonrigidity
phenomenon for Riemannian manifolds and convex billiards, and it motivates the
existence problem for similar 'partially length-isospectral' deformations of strictly
convex billiard tables.\r\n"

text: Amoeboid cell migration is key to efficient T cell immunity. Spatial polarization
of organelles within cells, including endo-lysosomes, is a prerequisite of migration.
However, how ultrastructural polarization is linked to the signaling requirements
governing T cell migration remains unknown. Here we show that signaling molecules
generated by endo-lysosome-localized kinases regulate velocity of amoeboid migration.
Specifically, imaging of T cells identifies accumulation of endo-lysosomes decorated
with the lipid kinases VPS34–PIKfyve at the uropod of polarized cells. Activity
of VPS34 and PIKfyve regulates speed, but not directedness, of migrating T cells.
Mechanistically, PI(3,5)P2 generated by the sequential action of VPS34 and PIKfyve,
mediates Ca2+ efflux from lysosomes via the mucolipin TRP cation channel 1 (TRPML1),
thus controlling activity of myosin IIA and hence the generation of propulsive
force through retrograde actin flow. The VPS34–PIKfyve kinases also regulate velocity
of myeloid cells, as well as of the amoeba Dictyostelium discoideum – establishing
the axis as an evolutionarily conserved speed control system of amoeboid cell
migration.

text: Gravitropism is a fundamental adaptive response in plants that enables directional
growth to optimize resource acquisition. In this study, we employed forward genetic
screening to identify Arabidopsis mutants with defective hypocotyl gravitropism
and isolated the short and agravitropic hypocotyl in dark1 (sad1) mutant, which
carries a point mutation (G110E) in the SAC1 gene encoding a phosphoinositide
phosphatase. Deficiency of SAC1 disrupted gravity-induced polar localization of
PIN3 in endodermal cells, impairing auxin redistribution and leading to hypocotyl
gravitropism defects. Subcellular localization analysis revealed that SAC1 is
partially localized to the PVC/tonoplast and participates in late endosomal trafficking.
The sac1 mutation leads to abnormal vacuolar morphology, which is associated with
defects in amyloplast sedimentation during the gravitropic response in Arabidopsis
shoots. We further revealed that SAC1 interacts with GRV2, a key regulator of
the late endocytic pathway, and that both proteins cooperatively regulate shoot
gravitropism. In summary, this study identified SAC1 as a regulator of shoot gravitropism,
revealing its important role in modulating vacuolar homeostasis, amyloplast sedimentation,
PIN3 trafficking, and auxin distribution. These findings provide insights into
the molecular mechanisms linking membrane transport to environmental adaptation
in plants.

text: "We study simple dynamics in the population protocol model, in\r\nwhich \U0001D45B
agents start with totally ordered initial opinions \U0001D4651, \U0001D4652, .
. . ,\r\n\U0001D465\U0001D45B and, in each round, a randomly chosen agent changes
its opinion\r\nas a function of the opinion of other randomly chosen agents. Such\r\ndynamics
often converge to consensus on a single fixation value \U0001D44Bˆ.\r\nThis paper
asks how to control the distribution of \U0001D44Bˆ as a randomised\r\nchoice
among the initial opinions by designing suitable simple\r\ndynamics. Writing the
sorted initial values as \U0001D465(1) ≤ · · · ≤ \U0001D465(\U0001D45B)\r\n,\r\nwe
design two protocols that realise natural target laws over order\r\nstatistics.\r\nFirst,
for a parameter \U0001D45D ∈ (0, 1), our geometric protocol biases\r\ntoward larger
opinions and satisfies P\r\n\r\n\U0001D44Bˆ = \U0001D465(\U0001D458)\r\n\r\n∝
\U0001D45D\r\n\U0001D45B−\U0001D458\r\n, for\r\n\U0001D458 = 1, . . . , \U0001D45B.
Equivalently, P\r\n\r\n\U0001D44Bˆ = \U0001D465(\U0001D458)\r\n\r\n= (1 − \U0001D45D)\U0001D45D\r\n\U0001D45B−\U0001D458\r\n/(1
− \U0001D45D\r\n\U0001D45B\r\n).\r\nSecond, our binomial protocol assigns a shifted
binomial law to the\r\nranks in ascending order: if \U0001D43E −1 ∼ Bin(\U0001D45B−1,
1−\U0001D45D), then \U0001D44Bˆ = \U0001D465(\U0001D43E)\r\n,\r\ni.e., P\r\n\r\n\U0001D44Bˆ
= \U0001D465(\U0001D458)\r\n\r\n=\r\n\U0001D45B−1\r\n\U0001D458−1\r\n\x01\r\n\U0001D45D\r\n\U0001D45B−\U0001D458\r\n(1
− \U0001D45D)\r\n\U0001D458−1\r\n, for \U0001D458 = 1, . . . , \U0001D45B.\r\nApplications
of this include computing the Top-\U0001D458 values for\r\nsmall \U0001D458 on
general interaction graphs. A central contribution of\r\nthis work is that, in
contrast to most population protocols, we can\r\ncharacterise the fixation distribution
in closed form. This is enabled\r\nby a novel analysis technique, which also yields
applications: we\r\nderive new results for the Median protocol that extend the
state of\r\nthe art."

text: "We study the Undecided-State Dynamics (USD), a fundamental consensus process
in which each vertex holds one of k decided opinions or the undecided state. We
consider both the gossip model and the population protocol model. Prior work established
tight bounds on the consensus time of this process only for the regime \r\nk\r\n=\r\nO\r\n(\r\nn\r\n/\r\n(\r\nlog\r\n\r\nn\r\n)\r\n2\r\n)\r\n
(for the population protocol model) and k = O((n/log n)1/3) (for the gossip model),
often under restrictive assumptions on the initial configuration.\r\nIn this paper,
we obtain the first consensus-time guarantees for USD that hold for arbitrary
2 ≤ k ≤ n and for arbitrary initial configurations in both the gossip model and
the population protocol model. In the gossip model, USD reaches consensus within
\r\nO\r\n~\r\n(\r\nmin\r\n{\r\nk\r\n,\r\nn\r\n}\r\n)\r\n synchronous rounds with
probability 1 - p⊥ - n-c, where p⊥ is the gossip-specific probability of collapsing
to the all-undecided state in the first round. In the population protocol model,
USD reaches consensus within \r\nO\r\n~\r\n(\r\nmin\r\n{\r\nk\r\nn\r\n,\r\nn\r\n3\r\n/\r\n2\r\n}\r\n)\r\n
asynchronous interactions with high probability. We also present lower bounds
that match the upper bounds up to polylogarithmic factors for a specific initial
configuration and show that our upper bounds are essentially optimal."

text: We report a unified method for the synthesis of α-polyhalomethyl amines from
alkenes and alkynes, enabled by readily available hemiaminal reagents. This operationally
simple transformation allows for the introduction of not only well-established
CF3 and CF2H groups, but also the synthetically (and medicinally) underexplored
CF2Cl and CFClH motifs—thereby broadening access to previously inaccessible chemical
space of halogenated amine scaffolds. The method displays broad substrate scope
and functional-group tolerance while operating under mild conditions. Late-stage
functionalization of drug-like derivatives of Oxaprozin, Erlotinib, and Ibuprofen
(among others) is reported.

text: Arrays of Josephson junctions can be tuned through anomalous metallic, quantum-critical,
and insulating regimes. We introduce an alternative experimental probe, capturing
microwave radiation across all three regimes, using a two-dimensional array of
superconductor-semiconductor hybrid Josephson junctions as a model system. Our
approach allows calibration of the sample’s circuit parameters and provides isolation
from measurement back-action effects. We measure the radiation temperature of
the anomalous metal and find that it is hotter than both the quantum-critical
and insulating regimes. We further show that the anomalous metallic regime is
more susceptible to additional heating than other regimes, explaining its emergence
in otherwise thermalized systems. Turning to the quantum-critical regime, we discover
nonlinear scaling of radiative noise with applied bias, consistent with theoretical
predictions of universal nonequilibrium behavior at quantum-critical points.

text: "Context. X-ray binaries exhibit complex variability patterns studied in the
power spectrum. These include the broadband noise (BBN)\r\ncomponents and various
types of narrow components called quasi-periodic oscillations (QPOs). There is
currently no consensus about\r\nwhat determines the presence or absence of the
BBN or what generates the QPOs. Many believe that QPO generation is due to framedragging
effects caused by Lense–Thirring torques.\r\nAims. We investigated the potential
impact of frame-dragging effects on the accretion disk itself. In particular,
we focused on its\r\nimpact on the observed variability and on the presence (and
types) of associated QPOs.\r\nMethods. We made analytical estimates to assess
the potential presence of a geometric warp in the inner accretion disk during
state\r\ntransitions.\r\nResults. We show that the presence of a warp can modify
the spectral-timing properties in a way that matches the observed transition\r\nbetween
QPO types during outbursts. We also discuss the peculiar case of Cyg X-1, as well
as how the hard-to-soft transition could\r\nbe driven by the warp itself.\r\nConclusions.
The (expected) emergence of a warp provides a consistent explanation for the evolution
of both the BBN and the QPO\r\nproperties during state transitions. This offers
a first path toward unifying the variability of black hole X-ray binaries."

text: 'Runtime fairness is not a one-time constraint but a dynamic property evaluated
over a sequence of decisions. To ensure fairness at runtime, it is necessary to
account for past decisions, information neglected by conventional, static classifiers.
Traditional fairness shields enforce runtime fairness abruptly, by intervening
deterministically whenever a sequence of decisions violates the target for a running
fairness measure. This motivates our main conceptual contribution: energy shields.
An energy shield is a novel, lightweight, adaptive controller that monitors a
sequence of decisions and intervenes probabilistically to ensure runtime fairness
smoothly, by utilizing physics-inspired energy functions to nudge the sequence
toward fairness: the more unfair the decisions, the stronger the nudging force
becomes. This makes energy shields the first fairness shields to provide both
short-term safety and long-term liveness guarantees. Safety ensures that the running
fairness measure stays within a running target interval with high probability,
and liveness ensures that the limit of the fairness measure lies within the limit
target interval. Intuitively, the short-term specifies the tolerated fairness
values and the long-term specifies the desired fairness values. We also provide
a synthesis procedure for constructing the least intrusive energy shield for a
given target specification, and demonstrate its efficiency experimentally. We
evaluate our energy shields against existing fairness shields through the lens
of short- and long-term fairness.'

text: On 26–28 September 2024, torrential rainfall struck Nepal during the late
monsoon season, causing flooding, landslides and extensive damage. This study
examined the multiscale processes contributing to this extreme precipitation event,
focusing on intraseasonal oscillations, synoptic-scale circulations, and mesoscale
cloud/precipitation systems. A quasi-biweekly intraseasonal oscillation dominated
over South Asia during the event, featuring a monsoon low-pressure system over
the Indian Peninsula and an anticyclone to its east, both propagating westward.
The pressure gradient between them sustained strong southerly moisture transport
toward the Himalayas, establishing a persistently humid environment and orographic
lift along the southern slopes. In contrast to reports of previous extreme precipitation
events in Nepal, the atmospheric circulation responsible for the 2024 event was
primarily of tropical origin, with minimal influence from the midlatitudes. Characteristic
mesoscale cloud/precipitation systems also developed around the Himalayas. The
highest daily precipitation during the event was recorded on 27 September; stratiform
systems with relatively modest storm top heights developed over the southern slopes,
generating surface precipitation rates of > 100 mm h− 1 through warm-rain processes.
Rain gauges across the glacierized basin (3500–5000 m asl) recorded exceptionally
high daily and hourly precipitation rates, highlighting the extension of intense
rainfall to unusually high elevations.

text: "In recent years there has been a massive increase in the amount of data generated
in a\r\ndecentralized manner. Ever more powerful edge devices, such as smartphones,
have become\r\nubiquitous in most societies on earth. Through text typed, photos
taken and apps used,\r\nthese devices, which we refer to as clients, generate
enormous amounts of high quality and\r\ncomplex data. Moreover, the nature of
these devices means the data they generate is often\r\nsensitive and privacy concerns
prevent it being gathered and stored in a central location. This\r\npresents a
challenge to the modern machine learning paradigm that requires central access\r\nto
large amounts of data. Federated learning (FL) has emerged as one of the answers
to\r\nthis problem. Rather than bringing the data to the model, FL sends the model
to the data.\r\nModel training takes place on device, with periodically synchronized
updates, allowing data to\r\nremain locally stored. While this approach offers
significant privacy advantages it comes with\r\nits own set of unique challenges.
These include: data heterogeneity, the notion that different\r\ndevices generate
data in distinct ways which can negatively impact training dynamics; systems\r\nheterogeneity,
meaning that different devices may have differing hardware specifications; high\r\ncommunication
costs, which are induced by the repeated transferring of models over the\r\nnetwork
and low device computational power, which limits the use of larger models on device.\r\nIn
this thesis we present a range of methods for federated learning. We focus primarily
on\r\nthe challenge of data heterogeneity, though the methods presented are designed
to be well\r\nadapted to the other challenges of a federated setting, such as
the constraints of limited\r\ncompute and communication overhead. We first present
a method for explicitly modeling client\r\ndata heterogeneity. The approach formulates
clients as samples from a certain probability\r\ndistribution and infers the parameters
of this distribution from the available training clients.\r\nThis learned distribution
then represents the heterogeneity present among the clients and can\r\nbe sampled
from in order to create new simulated clients that are similar to the real clients
we\r\nhave observed so far. Following this we present two methods for directly
dealing with data\r\nheterogeneity through personalization. Highly heterogeneous
client data distributions can mean\r\nthat learning a single global model becomes
suboptimal, and some form of personalization of\r\nmodels to each individual client
is required. Our approaches are based around hypernetworks,\r\nwhich we use to
generate personalized model parameters without the need for additional\r\ntraining
or finetuning. In the first approach we focus on generating full parameterizations
of\r\nclient models using learned embeddings of client data and labels, with a
hypernetwork located\r\non the central server. In the second approach we address
the more challenging scenario where\r\nwe want to generate a personalized model
for a client without any label information. The\r\nhypernetwork is trained to
generate a low dimensional representation of a client’s personalized\r\nmodel
parameters, allowing it to be transferred to and run on the client devices. In
our final\r\npresented method, we change our focus and rather than aim to directly
address the challenge\r\nof data heterogeneity, we instead ensure we are unaffected
by it. This is done in the context\r\nof k-means clustering and we present a method
for federated clustering with a focus on added\r\nprivacy guarantees."
