Characterizing how Visual Question Answering models scale with the world

Abstract

Detecting differences in generalization ability between models for visual question answering tasks has proven to be surprisingly difficult. We propose a new statistic, asymptotic sample complexity, for model comparison, and construct a synthetic data distribution to compare a strong baseline CNN-LSTM model to a structured neural network with powerful inductive biases. Our metric identifies a clear improvement in the structured model’s generalization ability relative to the baseline despite their similarity under existing metrics.

Eli Bingham
Eli is a research scientist working on probabilistic programming, approximate Bayesian inference, and grounded language understanding. He has previously worked on condensed matter physics, computational biology, climatology, multiscale dictionary learning, and deep learning for computer vision. In his spare time he hangs out in a lab tinkering with his nanopore DNA sequencer.
Piero Molino
Piero is a Staff Research Scientist in the Hazy research group at Stanford University. He is a former founding member of Uber AI where he created Ludwig, worked on applied projects (COTA, Graph Learning for Uber Eats, Uber’s Dialogue System) and published research on NLP, Dialogue, Visualization, Graph Learning, Reinforcement Learning and Computer Vision.
Paul Szerlip
Paul Szerlip earned his PhD with Dr. Kenneth Stanley at the University of Central Florida focusing on open-source infrastructure for collaborative evolutionary software. This open-source platform enables researchers to quickly integrate crowd-sourced human contributions with automated algorithms, while making the results easily accessible online. His later research highlighted new ways to integrate neuroevolutionary techniques like HyperNEAT and Novelty Search into deep learning frameworks.
Fritz Obermeyer
Fritz is a research engineer at Uber AI focusing on probabilistic programming. He is the engineering lead for the Pyro team.
Noah Goodman
In addition to working at Uber AI Labs, Noah is also an Associate Professor of Psychology, Computer Science, and Linguistics at Stanford University, where he runs the Computation and Cognition Lab.
