Conjugate Natural Selection
Reilly Raab, Luca de Alfaro, Yang Liu
We prove that Fisher-Rao natural gradient descent (FR-NGD) optimally approximates the continuous time replicator equation (an essential model of evolutionary dynamics), and term th…
Identifying Biased Subgroups in Ranking and Classification
Eliana Pastor, Luca de Alfaro, Elena Baralis
When analyzing the behavior of machine learning algorithms, it is important to identify specific data subgroups for which the considered algorithm shows different performance with…
Learning Edge Properties in Graphs from Path Aggregations
Rakshit Agrawal, Luca de Alfaro
Graph edges, along with their labels, can represent information of fundamental importance, such as links between web pages, friendship between users, the rating given by users to o…
A New Family of Neural Networks Provably Resistant to Adversarial Attacks
Rakshit Agrawal, Luca de Alfaro, David Helmbold
Adversarial attacks add perturbations to the input features with the intent of changing the classification produced by a machine learning system. Small perturbations can yield adve…
Learning From Graph Neighborhoods Using LSTMs
Rakshit Agrawal, Luca de Alfaro, Vassilis Polychronopoulos
Many prediction problems can be phrased as inferences over local neighborhoods of graphs. The graph represents the interaction between entities, and the neighborhood of each entity…
