SUMMARY:Lecture / Discussion:Colloquium: What Kinds of Functions Do Neural Networks Learn? Low-Norm vs. Flat Solutions
DESCRIPTION:This talk investigates the fundamental differences between low-norm and flat solutions of shallow ReLU networks training problems\, particularly in high-dimensional settings. We sharply characterize the regularity of the functions learned by neural networks in these two regimes. This enables us to show that global minima with small weight norms exhibit strong generalization guarantees that are dimension-independent. In contrast\, local minima that are “flat” can generalize poorly as the input dimension increases. We attribute this gap to a phenomenon we call neural shattering\, where neurons specialize to extremely sparse input regions\, resulting in activations that are nearly disjoint across data points. This forces the network to rely on large weight magnitudes\, leading to poor generalization. Our analysis establishes an exponential separation between flat and low-norm minima. In particular\, while flatness does imply some degree of generalization\, we show that the corresponding convergence rates necessarily deteriorate exponentially with input dimension. These findings suggest that flatness alone does not fully explain the generalization performance of neural networks.

SUMMARY:Workshop / Seminar:Exploring the structural biology of enteroviral genome replication
DESCRIPTION:The Enterovirus genus comprises RNA viruses associated with various illnesses\, including the common cold\, poliomyelitis\, acute flaccid paralysis\, and myocarditis. These viruses have conserved cloverleaf-shaped RNA secondary structures at the extreme 5′ end of their genomes\, which are crucial for assembling viral and host proteins\, such as 3CD and PCBP2\, into functional ribonucleoprotein (RNP) complexes required for genome replication. However\, the high-resolution structures and mechanisms of these cloverleaf RNAs have largely remained unknown. Recently\, we determined the crystal structures of five cloverleaf RNAs from different enteroviral species\, revealing a highly conserved H-type four-way junction fold that positions the 3CD and PCBP2 binding sites far apart. The conserved features observed in these structures\, including a long-range A•C•U base triple\, enabled us to predict structural models for other enteroviruses via homology modeling\, yielding models similar to the experimental structures. Our structure-guided binding analyses\, using recombinantly purified full-length human PCBP2 and viral 3C proteins\, along with the crystal structures of the cloverleaf-3C complexes\, offered further insights into how these viruses assemble RNP complexes for their genome replication within host cells. Moreover\, we demonstrated that antisense oligonucleotides could block high-affinity PCBP2-binding sites\, highlighting the potential to develop therapeutics targeting this replication platform for enteroviral infections. The notable structural conservation among enteroviral cloverleafs observed in our studies underscores opportunities to develop universal therapeutics that target this viral RNP platform across multiple enterovirus infections.
