Energy Based Models
Current Perspectives, Challenges, and Opportunities
ICLR2021 Workshop - May 7, 2021

About the Workshop
Energy-Based Models (EBMs) are a learning framework that assigns a quality score to any given input, its energy; contrary to probabilistic models, there is no a priori requirement that these scores be normalized (i.e. sum to one). Energies are typically computed through a neural network, and training an EBM corresponds to shaping the energy function such that data points nearby the underlying data manifold are associated with lower energies than data points that are far from it. Not imposing normalization affords a great power and flexibility to the modelling process, e.g. in terms of combining energies, on conditioning on certain variables, of computing global scores on complex structured objects, or on expressing prior knowledge. However, this freedom comes with significant technical challenges, in terms of learning and inference.
A strong comeback of EBMs is currently underway. The goals of this Workshop are:
To provide a forum for discussing cutting-edge research on different EBM approaches (e.g for continuous vs. discrete problems, strategies to shape the energy function, etc.), and to position these in the broader ML landscape (MCMC, GANs, RL, Variational Inference, etc.)
To bring together different communities, not only from core ML, but also from application domains such as vision, nlp, biology, neuroscience, etc.
To learn and exchange ideas about current and potential applications of EBMs, and to provide insights which may inspire novel EBM developments.
