When does mixup promote local linearity in learned representations?

no code implementations28 Oct 2022 Arslan Chaudhry, Aditya Krishna Menon, Andreas Veit, Sadeep Jayasumana, Srikumar Ramalingam, Sanjiv Kumar

Towards this, we study two questions: (1) how does the Mixup loss that enforces linearity in the \emph{last} network layer propagate the linearity to the \emph{earlier} layers?

RankDistil: Knowledge Distillation for Ranking

no code implementations AISTATS 2021 Sashank J. Reddi, Rama Kumar Pasumarthi, Aditya Krishna Menon, Ankit Singh Rawat Felix Yu, Seungyeon Kim, Andreas Veit, Sanjiv Kumar

Knowledge distillation is an approach to improve the performance of a student model by using the knowledge of a complex teacher. Despite its success in several deep learning applications, the study of distillation is mostly confined to classification settings.

Improving Calibration in Deep Metric Learning With Cross-Example Softmax

no code implementations17 Nov 2020 Andreas Veit, Kimberly Wilber

Triplet-based methods capture top-$k$ relevancy, where all top-$k$ scoring documents are assumed to be relevant to a given query Pairwise contrastive models capture threshold relevancy, where all documents scoring higher than some threshold are assumed to be relevant.

Doubly-stochastic mining for heterogeneous retrieval

no code implementations23 Apr 2020 Ankit Singh Rawat, Aditya Krishna Menon, Andreas Veit, Felix Yu, Sashank J. Reddi, Sanjiv Kumar

Modern retrieval problems are characterised by training sets with potentially billions of labels, and heterogeneous data distributions across subpopulations (e. g., users of a retrieval system may be from different countries), each of which poses a challenge.

Why are Adaptive Methods Good for Attention Models?

no code implementations NeurIPS 2020 Jingzhao Zhang, Sai Praneeth Karimireddy, Andreas Veit, Seungyeon Kim, Sashank J. Reddi, Sanjiv Kumar, Suvrit Sra
