Concept-Best-Matching: Evaluating Compositionality in Emergent Communication
Artificial agents that learn to communicate in order to accomplish a given task acquire communication protocols that are typically opaque to a human.
Statistical curriculum learning: An elimination algorithm achieving an oracle risk
In the single source case, we propose an elimination learning method, whose risk matches that of a strong-oracle learner.
Characterization of the Distortion-Perception Tradeoff for Finite Channels with Arbitrary Metrics
We provide a structural characterization of the DP tradeoff, where the DP function is piecewise linear in the perception index.
Identifying Dynamic Regulation with Adversarial Surrogates
Homeostasis, the ability to maintain a stable internal environment in the face of perturbations, is essential for the functioning of living systems.
Emergent Quantized Communication
The field of emergent communication aims to understand the characteristics of communication as it emerges from artificial agents solving tasks that require information exchange.

We present a PAC-Bayes-style generalization bound which enables the replacement of the KL-divergence with a variety of Integral Probability Metrics (IPM).
Online Meta-Learning in Adversarial Multi-Armed Bandits
This solution comprises an inner learner that plays each episode separately, and an outer learner that updates the hyper-parameters of the inner algorithm between the episodes.
Enhancing Causal Estimation through Unlabeled Offline Data
Our proposed approach consists of three stages: (i) Use the abundant offline data in order to create both a non-causal and a causal estimator for the relevant unmeasured physiological variables.
Metalearning Linear Bandits by Prior Update
In this work we prove, in the context of stochastic linear bandits and Gaussian priors, that as long as the prior is sufficiently close to the true prior, the performance of the applied algorithm is close to that of the algorithm that uses the true prior.

Generalization Bounds For Unsupervised and Semi-Supervised Learning With Autoencoders
Autoencoders are widely used for unsupervised learning and as a regularization scheme in semi-supervised learning.
Distributional Multivariate Policy Evaluation and Exploration with the Bellman GAN
In this formulation, DiRL can be seen as learning a deep generative model of the value distribution, driven by the discrepancy between the distribution of the current value, and the distribution of the sum of current reward and next value.
Lifelong Learning by Adjusting Priors
We develop a framework for lifelong learning in deep neural networks that is based on generalization bounds, developed within the PAC-Bayes framework.
Joint autoencoders: a flexible meta-learning framework
Ideally one would like to allow both the data for the current task and for previous related tasks to self-organize the learning system in such a way that commonalities and differences between the tasks are learned in a data-driven fashion.
Meta-Learning by Adjusting Priors Based on Extended PAC-Bayes Theory
In meta-learning an agent extracts knowledge from observed tasks, aiming to facilitate learning of novel future tasks.
