fAux: Testing Individual Fairness via Gradient Alignment

no code implementations10 Oct 2022 Giuseppe Castiglione, Ga Wu, Christopher Srinivasa, Simon Prince

We propose a novel criterion for evaluating individual fairness and develop a practical testing method based on this criterion which we call fAux (pronounced fox).

A Solver + Gradient Descent Training Algorithm for Deep Neural Networks

no code implementations7 Jul 2022 Dhananjay Ashok, Vineel Nagisetty, Christopher Srinivasa, Vijay Ganesh

We present a novel hybrid algorithm for training Deep Neural Networks that combines the state-of-the-art Gradient Descent (GD) method with a Mixed Integer Linear Programming (MILP) solver, outperforming GD and variants in terms of accuracy, as well as resource and data efficiency for both regression and classification tasks.

Nonlocal optimization of binary neural networks

no code implementations5 Apr 2022 Amir Khoshaman, Giuseppe Castiglione, Christopher Srinivasa

We explore training Binary Neural Networks (BNNs) as a discrete variable inference problem over a factor graph.

Parity Partition Coding for Sharp Multi-Label Classification

no code implementations23 Aug 2019 Christopher G. Blake, Giuseppe Castiglione, Christopher Srinivasa, Marcus Brubaker

The problem of efficiently training and evaluating image classifiers that can distinguish between a large number of object categories is considered.

Min-Max Propagation

no code implementations NeurIPS 2017 Christopher Srinivasa, Inmar Givoni, Siamak Ravanbakhsh, Brendan J. Frey

We study the application of min-max propagation, a variation of belief propagation, for approximate min-max inference in factor graphs.
