Sequential Variational Autoencoders for Collaborative Filtering

1 code implementation25 Nov 2018 Noveen Sachdeva, Giuseppe Manco, Ettore Ritacco, Vikram Pudi

We introduce a recurrent version of the VAE, where instead of passing a subset of the whole history regardless of temporal dependencies, we rather pass the consumption sequence subset through a recurrent neural network.

How Useful are Reviews for Recommendation? A Critical Review and Potential Improvements

1 code implementation25 May 2020 Noveen Sachdeva, Julian McAuley

We investigate a growing body of work that seeks to improve recommender systems through the use of review text.

Off-policy Bandits with Deficient Support

1 code implementation16 Jun 2020 Noveen Sachdeva, Yi Su, Thorsten Joachims

Learning effective contextual-bandit policies from past actions of a deployed system is highly desirable in many settings (e. g. voice assistants, recommendation, search), since it enables the reuse of large amounts of log data.

SVP-CF: Selection via Proxy for Collaborative Filtering Data

no code implementations11 Jul 2021 Noveen Sachdeva, Carole-Jean Wu, Julian McAuley

As we demonstrate, commonly-used data sampling schemes can have significant consequences on algorithm performance -- masking performance deficiencies in algorithms or altering the relative performance of algorithms, as compared to models trained on the complete dataset.

ECLARE: Extreme Classification with Label Graph Correlations

1 code implementation31 Jul 2021 Anshul Mittal, Noveen Sachdeva, Sheshansh Agrawal, Sumeet Agarwal, Purushottam Kar, Manik Varma

This paper presents ECLARE, a scalable deep learning architecture that incorporates not only label text, but also label correlations, to offer accurate real-time predictions within a few milliseconds.

On Sampling Collaborative Filtering Datasets

1 code implementation13 Jan 2022 Noveen Sachdeva, Carole-Jean Wu, Julian McAuley

We study the practical consequences of dataset sampling strategies on the ranking performance of recommendation algorithms.

Infinite Recommendation Networks: A Data-Centric Approach

5 code implementations3 Jun 2022 Noveen Sachdeva, Mehak Preet Dhaliwal, Carole-Jean Wu, Julian McAuley

We leverage the Neural Tangent Kernel and its equivalence to training infinitely-wide neural networks to devise $\infty$-AE: an autoencoder with infinitely-wide bottleneck layers.

Data Distillation: A Survey

1 code implementation11 Jan 2023 Noveen Sachdeva, Julian McAuley

The popularity of deep learning has led to the curation of a vast number of massive and multifarious datasets.

Farzi Data: Autoregressive Data Distillation

no code implementations15 Oct 2023 Noveen Sachdeva, Zexue He, Wang-Cheng Kang, Jianmo Ni, Derek Zhiyuan Cheng, Julian McAuley

We study data distillation for auto-regressive machine learning tasks, where the input and output have a strict left-to-right causal structure.
