Understanding ensemble learning

MBZUAI · Invalid Date

An associate professor of Statistics at the University of Toronto gave a talk on how ensemble learning stabilizes and improves the generalization performance of an individual interpolator. The talk focused on bagged linear interpolators and introduced the multiplier-bootstrap-based bagged least square estimator. The multiplier bootstrap encompasses the classical bootstrap with replacement as a special case, along with a Bernoulli bootstrap variant. Why it matters: While the talk occurred at MBZUAI, the content is about ensemble learning which is a core area for improving AI model performance, and is of general interest to the AI research community.

Ekaterina Radionova from Smarter AI (formerly Samsung AI Center) presented an approach to generating lifelike real-time avatars. The work focuses on generating high-quality video with authentic facial features to support online generation. Radionova's master's degree is from Skoltech on Data Science program and Bachelor degree at Moscow Institute of Physics and Technology on Applied Math. Why it matters: Achieving realistic real-time avatars is critical for applications in online communication, entertainment, and virtual reality within the region.

Generative models, manifolds and symmetries: From QFT to molecules

MBZUAI · Invalid Date

A DeepMind researcher presented work on incorporating symmetries into machine learning models, with applications to lattice-QCD and molecular dynamics. The work includes permutation and translation-invariant normalizing flows for free-energy estimation in molecular dynamics. They also presented U(N) and SU(N) Gauge-equivariant normalizing flows for pure Gauge simulations and its extensions to incorporate fermions in lattice-QCD. Why it matters: Applying symmetry principles to generative models could improve AI's ability to model complex physical systems relevant to materials science and other fields in the region.
