Substance or Style: What Does Your Image Embedding Know?

no code implementations10 Jul 2023 Cyrus Rashtchian, Charles Herrmann, Chun-Sung Ferng, Ayan Chakrabarti, Dilip Krishnan, Deqing Sun, Da-Cheng Juan, Andrew Tomkins

We find that image-text models (CLIP and ALIGN) are better at recognizing new examples of style transfer than masking-based models (CAN and MAE).

Approximating a RUM from Distributions on k-Slates

1 code implementation22 May 2023 Flavio Chierichetti, Mirko Giacchini, Ravi Kumar, Alessandro Panconesi, Andrew Tomkins

In this work we consider the problem of fitting Random Utility Models (RUMs) to user choices.

CARLS: Cross-platform Asynchronous Representation Learning System

1 code implementation26 May 2021 Chun-Ta Lu, Yun Zeng, Da-Cheng Juan, Yicheng Fan, Zhe Li, Jan Dlabal, Yi-Ting Chen, Arjun Gopalan, Allan Heydon, Chun-Sung Ferng, Reah Miyara, Ariel Fuxman, Futang Peng, Zhen Li, Tom Duerig, Andrew Tomkins

In this work, we propose CARLS, a novel framework for augmenting the capacity of existing deep learning frameworks by enabling multiple components -- model trainers, knowledge makers and knowledge banks -- to concertedly work together in an asynchronous fashion across hardware platforms.

Graph Autoencoders with Deconvolutional Networks

no code implementations22 Dec 2020 Jia Li, Tomas Yu, Da-Cheng Juan, Arjun Gopalan, Hong Cheng, Andrew Tomkins

Recent studies have indicated that Graph Convolutional Networks (GCNs) act as a \emph{low pass} filter in spectral domain and encode smoothed node representations.

Adversarial Robustness Across Representation Spaces

no code implementations CVPR 2021 Pranjal Awasthi, George Yu, Chun-Sung Ferng, Andrew Tomkins, Da-Cheng Juan

In this work we extend the above setting to consider the problem of training of deep neural networks that can be made simultaneously robust to perturbations applied in multiple natural representation spaces.

Surprise: Result List Truncation via Extreme Value Theory

no code implementations19 Oct 2020 Dara Bahri, Che Zheng, Yi Tay, Donald Metzler, Andrew Tomkins

Work in information retrieval has largely been centered around ranking and relevance: given a query, return some number of results ordered by relevance to the user.

Generative Models are Unsupervised Predictors of Page Quality: A Colossal-Scale Study

no code implementations17 Aug 2020 Dara Bahri, Yi Tay, Che Zheng, Donald Metzler, Cliff Brunk, Andrew Tomkins

Large generative language models such as GPT-2 are well-known for their ability to generate text as well as their utility in supervised downstream tasks via fine-tuning.

BusTr: Predicting Bus Travel Times from Real-Time Traffic

no code implementations2 Jul 2020 Richard Barnes, Senaka Buthpitiya, James Cook, Alex Fabrikant, Andrew Tomkins, Fangzhou Xu

We present BusTr, a machine-learned model for translating road traffic forecasts into predictions of bus delays, used by Google Maps to serve the majority of the world's public transit systems where no official real-time bus tracking is provided.

Choppy: Cut Transformer For Ranked List Truncation

no code implementations26 Apr 2020 Dara Bahri, Yi Tay, Che Zheng, Donald Metzler, Andrew Tomkins

Work in information retrieval has traditionally focused on ranking and relevance: given a query, return some number of results ordered by relevance to the user.

Reverse Engineering Configurations of Neural Text Generation Models

no code implementations ACL 2020 Yi Tay, Dara Bahri, Che Zheng, Clifford Brunk, Donald Metzler, Andrew Tomkins

This paper seeks to develop a deeper understanding of the fundamental properties of neural text generations models.

Graph Agreement Models for Semi-Supervised Learning

1 code implementation NeurIPS 2019 Otilia Stretcu, Krishnamurthy Viswanathan, Dana Movshovitz-Attias, Emmanouil Platanios, Sujith Ravi, Andrew Tomkins

To address this, we propose Graph Agreement Models (GAM), which introduces an auxiliary model that predicts the probability of two nodes sharing the same label as a learned function of their features.

Preventing Adversarial Use of Datasets through Fair Core-Set Construction

no code implementations24 Oct 2019 Benjamin Spector, Ravi Kumar, Andrew Tomkins

We propose improving the privacy properties of a dataset by publishing only a strategically chosen "core-set" of the data containing a subset of the instances.

Graph-RISE: Graph-Regularized Image Semantic Embedding

1 code implementation14 Feb 2019 Da-Cheng Juan, Chun-Ta Lu, Zhen Li, Futang Peng, Aleksei Timofeev, Yi-Ting Chen, Yaxi Gao, Tom Duerig, Andrew Tomkins, Sujith Ravi

Learning image representations to capture fine-grained semantics has been a challenging and important task enabling many applications such as image search and clustering.

Learning a Mixture of Two Multinomial Logits

no code implementations ICML 2018 Flavio Chierichetti, Ravi Kumar, Andrew Tomkins

In this model, a user is offered a slate of choices (a subset of a finite universe of $n$ items), and selects exactly one item from the slate, each with probability proportional to its (positive) weight.

Linear Additive Markov Processes

1 code implementation5 Apr 2017 Ravi Kumar, Maithra Raghu, Tamas Sarlos, Andrew Tomkins

We introduce LAMP: the Linear Additive Markov Process.

Smart Reply: Automated Response Suggestion for Email

no code implementations15 Jun 2016 Anjuli Kannan, Karol Kurach, Sujith Ravi, Tobias Kaufmann, Andrew Tomkins, Balint Miklos, Greg Corrado, Laszlo Lukacs, Marina Ganea, Peter Young, Vivek Ramavajjala

In this paper we propose and investigate a novel end-to-end method for automatically generating short email responses, called Smart Reply.
