  text: "Cardiac T1 mapping provides critical quantitative insights into myocardial
    tissue composition, enabling the assessment of pathologies such as fibrosis, inflammation,
    and edema.\r\nHowever, the inherently dynamic nature of the heart imposes strict
    limits on acquisition\r\ntimes, making high-resolution T1 mapping a persistent
    challenge. Compressed sensing (CS)\r\napproaches have reduced scan durations by
    undersampling k-space and reconstructing images from partial data, and recent
    studies show that jointly optimizing the undersampling\r\npatterns with the reconstruction
    network can substantially improve performance. Still,\r\nmost current T1 mapping
    pipelines rely on static, hand-crafted masks that do not exploit\r\nthe full acceleration
    and accuracy potential. Furthermore, most existing methods do not\r\nlevarage
    the physical T1 decay model in optimization. In this work, we introduce T1-\r\nPILOT:
    an end-to-end method that explicitly incorporates the T1 signal relaxation model\r\ninto
    the sampling–reconstruction framework to guide the learning of non-Cartesian trajectories,
    cross-frame alignment, and T1 decay estimation. Through extensive experiments\r\non
    the CMRxRecon dataset, T1-PILOT significantly outperforms several baseline strategies
    (including learned single-mask and fixed radial or golden-angle sampling schemes),\r\nachieving
    higher T1 map fidelity at greater acceleration factors. In particular, we observe
    consistent gains in PSNR and VIF relative to existing methods, along with marked\r\nimprovements
    in delineating finer myocardial structures. Our results highlight that optimizing
    sampling trajectories in tandem with the physical relaxation model leads to both\r\nenhanced
    quantitative accuracy and reduced acquisition times. Code for reproducing all\r\nexperiments
    and results is available at https://github.com/tamirshor7/T1-PILOT"

  text: We study differentially private model training with stochastic gradient descent
    under learning rate scheduling and correlated noise. Although correlated noise,
    in particular via matrix factorizations, has been shown to improve accuracy, prior
    theoretical work focused primarily on the prefix-sum workload. That workload assumes
    a constant learning rate, whereas in practice learning rate schedules are widely
    used to accelerate training and improve convergence. We close this gap by deriving
    general upper and lower bounds for a broad class of learning rate schedules in
    both single- and multi-epoch settings. Building on these results, we propose a
    learning-rate-aware factorization that achieves improvements over prefix-sum factorizations
    under both MaxSE and MeanSE error metrics. Our theoretical analysis yields memory-efficient
    constructions suitable for practical deployment, and experiments on CIFAR-10 and
    IMDB datasets confirm that schedule-aware factorizations improve accuracy in private
    training.

  text: 'Modern computer systems store vast amounts of personal data, enabling advances
    in AI and ML but risking user privacy and trust. For privacy reasons, it is sometimes
    desired for an ML model to forget part of the data it was trained on. In this
    paper, we introduce a novel unlearning approach based on Forgetting Neural Networks
    (FNNs), a neuroscience-inspired architecture that explicitly encodes forgetting
    through multiplicative decay factors. While FNNs had previously been studied as
    a theoretical construct, we provide the first concrete implementation and demonstrate
    their effectiveness for targeted unlearning. We propose several variants with
    per-neuron forgetting factors, including rank-based assignments guided by activation
    levels, and evaluate them on MNIST and Fashion-MNIST benchmarks. Our method systematically
    removes information associated with forget sets while preserving performance on
    retained data. Membership inference attacks confirm the effectiveness of FNN-based
    unlearning in erasing information about the training data from the neural network.
    These results establish FNNs as a promising foundation for efficient and interpretable
    unlearning. '

  text: "Making decisions requires flexibly adapting to changing environments, a process
    that\r\ndepends on accurately interpreting current contingencies and integrating
    them with\r\npast experience. Two brain regions are particularly critical for
    this process, the medial\r\nprefrontal cortex (mPFC) and the hippocampus. Using
    contextual information from the\r\nhippocampus, the mPFC selects relevant cognitive
    frameworks and suppresses\r\nirrelevant ones to guide appropriate actions. Several
    studies have shown that some\r\nmPFC pyramidal neurons become spatially tuned
    when spatial information is required\r\nto guide goal-directed behavior. However,
    the role of prefrontal spatial representations\r\nin learning and decision making
    is not well understood. This work aims to characterize\r\nthe role of mPFC spatial
    tuning in supporting a contextual association task. Rats were\r\ntrained to learn
    two cue–location associations on a radial arm maze over multiple days,\r\nwhile
    we simultaneously recorded from dorsal CA1 of the hippocampus and the\r\nprelimbic
    area of the mPFC. We describe a subset of spatially tuned hippocampal and\r\nprefrontal
    pyramidal neurons that “flicker” between multiple spatial representations on\r\ndifferent
    trials, suggesting dynamic, context-dependent coding. This flickering may\r\nprovide
    a substrate for how the network reorganizes in response to task demands,\r\nlikely
    by enabling the flexible evaluation of competing representations. "

  text: "3D printing based on continuous deposition of materials, such as filament-based
    3D printing, has seen widespread adoption thanks to its versatility in working
    with a wide range of materials. An important shortcoming of this type of technology
    is its limited multi-material capabilities. While there are simple hardware designs
    that enable multi-material printing in principle, the required software is heavily
    underdeveloped. A typical hardware design fuses together individual materials
    fed into a single chamber from multiple inlets before they are deposited. This
    design, however, introduces a time delay between the intended material mixture
    and its actual deposition. In this work, inspired by diverse path planning research
    in robotics, we show that this mechanical challenge can be addressed via improved
    printer control. We propose to formulate the search for optimal multi-material
    printing policies in a reinforcement\r\nlearning setup. We put forward a simple
    numerical deposition model that takes into account the non-linear material mixing
    and delayed material deposition. To validate our system we focus on color fabrication,
    a problem known for its strict requirements for varying material mixtures at a
    high spatial frequency. We demonstrate that our learned control policy outperforms
    state-of-the-art hand-crafted algorithms."

  text: "Because of the increasing popularity of machine learning methods, it is becoming
    important to understand the impact of learned components on automated decision-making
    systems and to guarantee that their consequences are beneficial to society. In
    other words, it is necessary to ensure that machine learning is sufficiently trustworthy
    to be used in real-world applications. This thesis studies two properties of machine
    learning models that are highly desirable for the\r\nsake of reliability: robustness
    and fairness. In the first part of the thesis we study the robustness of learning
    algorithms to training data corruption. Previous work has shown that machine learning
    models are vulnerable to a range\r\nof training set issues, varying from label
    noise through systematic biases to worst-case data manipulations. This is an especially
    relevant problem from a present perspective, since modern machine learning methods
    are particularly data hungry and therefore practitioners often have to rely on
    data collected from various external sources, e.g. from the Internet, from app
    users or via crowdsourcing. Naturally, such sources vary greatly in the quality
    and reliability of the\r\ndata they provide. With these considerations in mind,
    we study the problem of designing machine learning algorithms that are robust
    to corruptions in data coming from multiple sources. We show that, in contrast
    to the case of a single dataset with outliers, successful learning within this
    model is possible both theoretically and practically, even under worst-case data
    corruptions. The second part of this thesis deals with fairness-aware machine
    learning. There are multiple areas where machine learning models have shown promising
    results, but where careful considerations are required, in order to avoid discrimanative
    decisions taken by such learned components. Ensuring fairness can be particularly
    challenging, because real-world training datasets are expected to contain various
    forms of historical bias that may affect the learning process. In this thesis
    we show that data corruption can indeed render the problem of achieving fairness
    impossible, by tightly characterizing the theoretical limits of fair learning
    under worst-case data manipulations. However, assuming access to clean data, we
    also show how fairness-aware learning can be made practical in contexts beyond
    binary classification, in particular in the challenging learning to rank setting."

  text: "Addressing fairness concerns about machine learning models is a crucial step
    towards their long-term adoption in real-world automated systems. While many approaches
    have been developed for training fair models from data, little is known about
    the robustness of these methods to data corruption. In this work we consider fairness-aware
    learning under worst-case data manipulations. We show that an adversary can in
    some situations force any learner to return an overly biased classifier, regardless
    of the sample size and with or without degrading\r\naccuracy, and that the strength
    of the excess bias increases for learning problems with underrepresented protected
    groups in the data. We also prove that our hardness results are tight up to constant
    factors. To this end, we study two natural learning algorithms that optimize for
    both accuracy and fairness and show that these algorithms enjoy guarantees that
    are order-optimal in terms of the corruption ratio and the protected groups frequencies
    in the large data\r\nlimit."

  text: "Deep learning has enabled breakthroughs in challenging computing problems
    and has emerged as the standard problem-solving tool for computer vision and natural
    language processing tasks.\r\nOne exception to this trend is safety-critical tasks
    where robustness and resilience requirements contradict the black-box nature of
    neural networks. \r\nTo deploy deep learning methods for these tasks, it is vital
    to provide guarantees on neural network agents' safety and robustness criteria.
    \r\nThis can be achieved by developing formal verification methods to verify the
    safety and robustness properties of neural networks.\r\n\r\nOur goal is to design,
    develop and assess safety verification methods for neural networks to improve
    their reliability and trustworthiness in real-world applications.\r\nThis thesis
    establishes techniques for the verification of compressed and adversarially trained
    models as well as the design of novel neural networks for verifiably safe decision-making.\r\n\r\nFirst,
    we establish the problem of verifying quantized neural networks. Quantization
    is a technique that trades numerical precision for the computational efficiency
    of running a neural network and is widely adopted in industry.\r\nWe show that
    neglecting the reduced precision when verifying a neural network can lead to wrong
    conclusions about the robustness and safety of the network, highlighting that
    novel techniques for quantized network verification are necessary. We introduce
    several bit-exact verification methods explicitly designed for quantized neural
    networks and experimentally confirm on realistic networks that the network's robustness
    and other formal properties are affected by the quantization.\r\n\r\nFurthermore,
    we perform a case study providing evidence that adversarial training, a standard
    technique for making neural networks more robust, has detrimental effects on the
    network's performance. This robustness-accuracy tradeoff has been studied before
    regarding the accuracy obtained on classification datasets where each data point
    is independent of all other data points. On the other hand, we investigate the
    tradeoff empirically in robot learning settings where a both, a high accuracy
    and a high robustness, are desirable.\r\nOur results suggest that the negative
    side-effects of adversarial training outweigh its robustness benefits in practice.\r\n\r\nFinally,
    we consider the problem of verifying safety when running a Bayesian neural network
    policy in a feedback loop with systems over the infinite time horizon. Bayesian
    neural networks are probabilistic models for learning uncertainties in the data
    and are therefore often used on robotic and healthcare applications where data
    is inherently stochastic.\r\nWe introduce a method for recalibrating Bayesian
    neural networks so that they yield probability distributions over safe decisions
    only.\r\nOur method learns a safety certificate that guarantees safety over the
    infinite time horizon to determine which decisions are safe in every possible
    state of the system.\r\nWe demonstrate the effectiveness of our approach on a
    series of reinforcement learning benchmarks."

  text: High-resolution visualization and quantification of membrane proteins contribute
    to the understanding of their functions and the roles they play in physiological
    and pathological conditions. Sodium dodecyl sulfate-digested freeze-fracture replica
    labeling (SDS-FRL) is a powerful electron microscopy method to study quantitatively
    the two-dimensional distribution of transmembrane proteins and their tightly associated
    proteins. During treatment with SDS, intracellular organelles and proteins not
    anchored to the replica are dissolved, whereas integral membrane proteins captured
    and stabilized by carbon/platinum deposition remain on the replica. Their intra-
    and extracellular domains become exposed on the surface of the replica, facilitating
    the accessibility of antibodies and, therefore, providing higher labeling efficiency
    than those obtained with other immunoelectron microscopy techniques. In this chapter,
    we describe the protocols of SDS-FRL adapted for mammalian brain samples, and
    optimization of the SDS treatment to increase the labeling efficiency for quantification
    of Cav2.1, the alpha subunit of P/Q-type voltage-dependent calcium channels utilizing
    deep learning algorithms.

  text: 'For a solar-like star, the surface rotation evolves with time, allowing in
    principle to estimate the age of a star from its surface rotation period. Here
    we are interested in measuring surface rotation periods of solar-like stars observed
    by the NASA mission Kepler. Different methods have been developed to track rotation
    signals in Kepler photometric light curves: time-frequency analysis based on wavelet
    techniques, autocorrelation and composite spectrum. We use the learning abilities
    of random forest classifiers to take decisions during two crucial steps of the
    analysis. First, given some input parameters, we discriminate the considered Kepler
    targets between rotating MS stars, non-rotating MS stars, red giants, binaries
    and pulsators. We then use a second classifier only on the MS rotating targets
    to decide the best data analysis treatment.'

  text: 'The second mission of NASA’s Kepler satellite, K2, has collected hundreds
    of thousands of lightcurves for stars close to the ecliptic plane. This new sample
    could increase the number of known pulsating stars and then improve our understanding
    of those stars. For the moment only a few stars have been properly classified
    and published. In this work, we present a method to automaticly classify K2 pulsating
    stars using a Machine Learning technique called Random Forest. The objective is
    to sort out the stars in four classes: red giant (RG), main-sequence Solar-like
    stars (SL), classical pulsators (PULS) and Other. To do this we use the effective
    temperatures and the luminosities of the stars as well as the FliPer features,
    that measures the amount of power contained in the power spectral density. The
    classifier now retrieves the right classification for more than 80% of the stars.'
