  text: "Despite their recent success, deep neural networks continue to perform poorly
    when they encounter distribution shifts at test time. Many recently proposed approaches
    try to counter this by aligning the model to the new distribution prior to inference.
    With no labels available this requires unsupervised objectives to adapt the model
    on the observed test data. In this paper, we propose Test-Time SelfTraining (TeST):
    a technique that takes as input a model trained on some source data and a novel
    data distribution at test time, and learns invariant and robust representations
    using a student-teacher framework. We find that models adapted using TeST significantly
    improve over baseline testtime adaptation algorithms. TeST achieves competitive
    performance to modern domain adaptation algorithms [4, 43], while having access
    to 5-10x less data at time of adaption. We thoroughly evaluate a variety of baselines
    on two tasks:\r\nobject detection and image segmentation and find that models
    adapted with TeST. We find that TeST sets the new stateof-the art for test-time
    domain adaptation algorithms. "

  text: For the Fröhlich model of the large polaron, we prove that the ground state
    energy as a function of the total momentum has a unique global minimum at momentum
    zero. This implies the non-existence of a ground state of the translation invariant
    Fröhlich Hamiltonian and thus excludes the possibility of a localization transition
    at finite coupling.

  text: The binding problem in human cognition, concerning how the brain represents
    and connects objects within a fixed network of neural connections, remains a subject
    of intense debate. Most machine learning efforts addressing this issue in an unsupervised
    setting have focused on slot-based methods, which may be limiting due to their
    discrete nature and difficulty to express uncertainty. Recently, the Complex AutoEncoder
    was proposed as an alternative that learns continuous and distributed object-centric
    representations. However, it is only applicable to simple toy data. In this paper,
    we present Rotating Features, a generalization of complex-valued features to higher
    dimensions, and a new evaluation procedure for extracting objects from distributed
    representations. Additionally, we show the applicability of our approach to pre-trained
    features. Together, these advancements enable us to scale distributed object-centric
    representations from simple toy to real-world data. We believe this work advances
    a new paradigm for addressing the binding problem in machine learning and has
    the potential to inspire further innovation in the field.

  text: This paper focuses on over-parameterized deep neural networks (DNNs) with
    ReLU activation functions and proves that when the data distribution is well-separated,
    DNNs can achieve Bayes-optimal test error for classification while obtaining (nearly)
    zero-training error under the lazy training regime. For this purpose, we unify
    three interrelated concepts of overparameterization, benign overfitting, and the
    Lipschitz constant of DNNs. Our results indicate that interpolating with smoother
    functions leads to better generalization. Furthermore, we investigate the special
    case where interpolating smooth ground-truth functions is performed by DNNs under
    the Neural Tangent Kernel (NTK) regime for generalization. Our result demonstrates
    that the generalization error converges to a constant order that only depends
    on label noise and initialization noise, which theoretically verifies benign overfitting.
    Our analysis provides a tight lower bound on the normalized margin under non-smooth
    activation functions, as well as the minimum eigenvalue of NTK under high-dimensional
    settings, which has its own interest in learning theory.

  text: Diffusion models excel at generating photorealistic images from text-queries.
    Naturally, many approaches have been proposed to use these generative abilities
    to augment training datasets for downstream tasks, such as classification. However,
    diffusion models are themselves trained on large noisily supervised, but nonetheless,
    annotated datasets. It is an open question whether the generalization capabilities
    of diffusion models beyond using the additional data of the pre-training process
    for augmentation lead to improved downstream performance. We perform a systematic
    evaluation of existing methods to generate images from diffusion models and study
    new extensions to assess their benefit for data augmentation. While we find that
    personalizing diffusion models towards the target data outperforms simpler prompting
    strategies, we also show that using the training data of the diffusion model alone,
    via a simple nearest neighbor retrieval procedure, leads to even stronger downstream
    performance. Overall, our study probes the limitations of diffusion models for
    data augmentation but also highlights its potential in generating new training
    data to improve performance on simple downstream vision tasks.

  text: Recovering the latent factors of variation of high dimensional data has so
    far focused on simple synthetic settings. Mostly building on unsupervised and
    weakly-supervised objectives, prior work missed out on the positive implications
    for representation learning on real world data. In this work, we propose to leverage
    knowledge extracted from a diversified set of supervised tasks to learn a common
    disentangled representation. Assuming each supervised task only depends on an
    unknown subset of the factors of variation, we disentangle the feature space of
    a supervised multi-task model, with features activating sparsely across different
    tasks and information being shared as appropriate. Importantly, we never directly
    observe the factors of variations but establish that access to multiple tasks
    is sufficient for identifiability under sufficiency and minimality assumptions.
    We validate our approach on six real world distribution shift benchmarks, and
    different data modalities (images, text), demonstrating how disentangled representations
    can be transferred to real settings.

  text: 'Causal discovery methods are intrinsically constrained by the set of assumptions
    needed to ensure structure identifiability. Moreover additional restrictions are
    often imposed in order to simplify the inference task: this is the case for the
    Gaussian noise assumption on additive non-linear models, which is common to many
    causal discovery approaches. In this paper we show the shortcomings of inference
    under this hypothesis, analyzing the risk of edge inversion under violation of
    Gaussianity of the noise terms. Then, we propose a novel method for inferring
    the topological ordering of the variables in the causal graph, from data generated
    according to an additive non-linear model with a generic noise distribution. This
    leads to NoGAM (Not only Gaussian Additive noise Models), a causal discovery algorithm
    with a minimal set of assumptions and state of the art performance, experimentally
    benchmarked on synthetic data.'

  text: This paper demonstrates how to discover the whole causal graph from the second
    derivative of the log-likelihood in observational non-linear additive Gaussian
    noise models. Leveraging scalable machine learning approaches to approximate the
    score function ∇logp(X), we extend the work of Rolland et al. (2022) that only
    recovers the topological order from the score and requires an expensive pruning
    step removing spurious edges among those admitted by the ordering. Our analysis
    leads to DAS (acronym for Discovery At Scale), a practical algorithm that reduces
    the complexity of the pruning by a factor proportional to the graph size. In practice,
    DAS achieves competitive accuracy with current state-of-the-art while being over
    an order of magnitude faster. Overall, our approach enables principled and scalable
    causal discovery, significantly lowering the compute bar.

  text: 'Recent years have seen a surge of interest in learning high-level causal
    representations from low-level image pairs under interventions. Yet, existing
    efforts are largely limited to simple synthetic settings that are far away from
    real-world problems. In this paper, we present Causal Triplet, a causal representation
    learning benchmark featuring not only visually more complex scenes, but also two
    crucial desiderata commonly overlooked in previous works: (i) an actionable counterfactual
    setting, where only certain object-level variables allow for counterfactual observations
    whereas others do not; (ii) an interventional downstream task with an emphasis
    on out-of-distribution robustness from the independent causal mechanisms principle.
    Through extensive experiments, we find that models built with the knowledge of
    disentangled or object-centric representations significantly outperform their
    distributed counterparts. However, recent causal representation learning methods
    still struggle to identify such latent structures, indicating substantial challenges
    and opportunities for future work.'

  text: 'Neural networks embed the geometric structure of a data manifold lying in
    a high-dimensional space into latent representations. Ideally, the distribution
    of the data points in the latent space should depend only on the task, the data,
    the loss, and other architecture-specific constraints. However, factors such as
    the random weights initialization, training hyperparameters, or other sources
    of randomness in the training phase may induce incoherent latent spaces that hinder
    any form of reuse. Nevertheless, we empirically observe that, under the same data
    and modeling choices, the angles between the encodings within distinct latent
    spaces do not change. In this work, we propose the latent similarity between each
    sample and a fixed set of anchors as an alternative data representation, demonstrating
    that it can enforce the desired invariances without any additional training. We
    show how neural architectures can leverage these relative representations to guarantee,
    in practice, invariance to latent isometries and rescalings, effectively enabling
    latent space communication: from zero-shot model stitching to latent space comparison
    between diverse settings. We extensively validate the generalization capability
    of our approach on different datasets, spanning various modalities (images, text,
    graphs), tasks (e.g., classification, reconstruction) and architectures (e.g.,
    CNNs, GCNs, transformers).'

  text: Humans naturally decompose their environment into entities at the appropriate
    level of abstraction to act in the world. Allowing machine learning algorithms
    to derive this decomposition in an unsupervised way has become an important line
    of research. However, current methods are restricted to simulated data or require
    additional information in the form of motion or depth in order to successfully
    discover objects. In this work, we overcome this limitation by showing that reconstructing
    features from models trained in a self-supervised manner is a sufficient training
    signal for object-centric representations to arise in a fully unsupervised way.
    Our approach, DINOSAUR, significantly out-performs existing image-based object-centric
    learning models on simulated data and is the first unsupervised object-centric
    model that scales to real-world datasets such as COCO and PASCAL VOC. DINOSAUR
    is conceptually simple and shows competitive performance compared to more involved
    pipelines from the computer vision literature.

  text: "In this paper, we show that recent advances in self-supervised feature\r\nlearning
    enable unsupervised object discovery and semantic segmentation with a\r\nperformance
    that matches the state of the field on supervised semantic\r\nsegmentation 10
    years ago. We propose a methodology based on unsupervised\r\nsaliency masks and
    self-supervised feature clustering to kickstart object\r\ndiscovery followed by
    training a semantic segmentation network on pseudo-labels\r\nto bootstrap the
    system on images with multiple objects. We present results on\r\nPASCAL VOC that
    go far beyond the current state of the art (50.0 mIoU), and we\r\nreport for the
    first time results on MS COCO for the whole set of 81 classes:\r\nour method discovers
    34 categories with more than $20\\%$ IoU, while obtaining\r\nan average IoU of
    19.6 for all 81 categories."

  text: Learning generative object models from unlabelled videos is a long standing
    problem and required for causal scene modeling. We decompose this problem into
    three easier subtasks, and provide candidate solutions for each of them. Inspired
    by the Common Fate Principle of Gestalt Psychology, we first extract (noisy) masks
    of moving objects via unsupervised motion segmentation. Second, generative models
    are trained on the masks of the background and the moving objects, respectively.
    Third, background and foreground models are combined in a conditional "dead leaves"
    scene model to sample novel scene configurations where occlusions and depth layering
    arise naturally. To evaluate the individual stages, we introduce the Fishbowl
    dataset positioned between complex real-world scenes and common object-centric
    benchmarks of simplistic objects. We show that our approach allows learning generative
    models that generalize beyond the occlusions present in the input videos, and
    represent scenes in a modular fashion that allows sampling plausible scenes outside
    the training distribution by permitting, for instance, object numbers or densities
    not observed in the training set.

  text: We demonstrate that a sodium dimer, Na2(13Σ+u), residing on the surface of
    a helium nanodroplet, can be set into rotation by a nonresonant 1.0 ps infrared
    laser pulse. The time-dependent degree of alignment measured, exhibits a periodic,
    gradually decreasing structure that deviates qualitatively from that expected
    for gas-phase dimers. Comparison to alignment dynamics calculated from the time-dependent
    rotational Schrödinger equation shows that the deviation is due to the alignment
    dependent interaction between the dimer and the droplet surface. This interaction
    confines the dimer to the tangential plane of the droplet surface at the point
    where it resides and is the reason that the observed alignment dynamics is also
    well described by a 2D quantum rotor model.

  text: This paper introduces a novel method for simulating large bodies of water
    as a height field. At the start of each time step, we partition the waves into
    a bulk flow (which approximately satisfies the assumptions of the shallow water
    equations) and surface waves (which approximately satisfy the assumptions of Airy
    wave theory). We then solve the two wave regimes separately using appropriate
    state-of-the-art techniques, and re-combine the resulting wave velocities at the
    end of each step. This strategy leads to the first heightfield wave model capable
    of simulating complex interactions between both deep and shallow water effects,
    like the waves from a boat wake sloshing up onto a beach, or a dam break producing
    wave interference patterns and eddies. We also analyze the numerical dispersion
    created by our method and derive an exact correction factor for waves at a constant
    water depth, giving us a numerically perfect re-creation of theoretical water
    wave dispersion patterns.

  text: We present a technique to optimize the reflectivity of a surface while preserving
    its overall shape. The naïve optimization of the mesh vertices using the gradients
    of reflectivity simulations results in undesirable distortion. In contrast, our
    robust formulation optimizes the surface normal as an independent variable that
    bridges the reflectivity term with differential rendering, and the regularization
    term with as-rigid-as-possible elastic energy. We further adaptively subdivide
    the input mesh to improve the convergence. Consequently, our method can minimize
    the retroreflectivity of a wide range of input shapes, resulting in sharply creased
    shapes ubiquitous among stealth aircraft and Sci-Fi vehicles. Furthermore, by
    changing the reward for the direction of the outgoing light directions, our method
    can be applied to other reflectivity design tasks, such as the optimization of
    architectural walls to concentrate light in a specific region. We have tested
    the proposed method using light-transport simulations and real-world 3D-printed
    objects.

  text: We study the problem of training and certifying adversarially robust quantized
    neural networks (QNNs). Quantization is a technique for making neural networks
    more efficient by running them using low-bit integer arithmetic and is therefore
    commonly adopted in industry. Recent work has shown that floating-point neural
    networks that have been verified to be robust can become vulnerable to adversarial
    attacks after quantization, and certification of the quantized representation
    is necessary to guarantee robustness. In this work, we present quantization-aware
    interval bound propagation (QA-IBP), a novel method for training robust QNNs.
    Inspired by advances in robust learning of non-quantized networks, our training
    algorithm computes the gradient of an abstract representation of the actual network.
    Unlike existing approaches, our method can handle the discrete semantics of QNNs.
    Based on QA-IBP, we also develop a complete verification procedure for verifying
    the adversarial robustness of QNNs, which is guaranteed to terminate and produce
    a correct answer. Compared to existing approaches, the key advantage of our verification
    procedure is that it runs entirely on GPU or other accelerator devices. We demonstrate
    experimentally that our approach significantly outperforms existing methods and
    establish the new state-of-the-art for training and certifying the robustness
    of QNNs.

  text: 'Two-player zero-sum "graph games" are central in logic, verification, and
    multi-agent systems. The game proceeds by placing a token on a vertex of a graph,
    and allowing the players to move it to produce an infinite path, which determines
    the winner or payoff of the game. Traditionally, the players alternate turns in
    moving the token. In "bidding games", however, the players have budgets and in
    each turn, an auction (bidding) determines which player moves the token. So far,
    bidding games have only been studied as full-information games. In this work we
    initiate the study of partial-information bidding games: we study bidding games
    in which a player''s initial budget is drawn from a known probability distribution.
    We show that while for some bidding mechanisms and objectives, it is straightforward
    to adapt the results from the full-information setting to the partial-information
    setting, for others, the analysis is significantly more challenging, requires
    new techniques, and gives rise to interesting results. Specifically, we study
    games with "mean-payoff" objectives in combination with "poorman" bidding. We
    construct optimal strategies for a partially-informed player who plays against
    a fully-informed adversary. We show that, somewhat surprisingly, the "value" under
    pure strategies does not necessarily exist in such games.'
