A/B testing under Interference with Partial Network Information

no code implementations16 Apr 2024 Shiv Shankar, Ritwik Sinha, Yash Chandak, Saayan Mitra, Madalina Fiterau

A/B tests are often required to be conducted on subjects that might have social connections.

HanDiffuser: Text-to-Image Generation With Realistic Hand Appearances

no code implementations4 Mar 2024 Supreeth Narasimhaswamy, Uttaran Bhattacharya, Xiang Chen, Ishita Dasgupta, Saayan Mitra, Minh Hoai

To generate images with realistic hands, we propose a novel diffusion-based architecture called HanDiffuser that achieves realism by injecting hand embeddings in the generative process.

SODA: Protecting Proprietary Information in On-Device Machine Learning Models

no code implementations22 Dec 2023 Akanksha Atrey, Ritwik Sinha, Saayan Mitra, Prashant Shenoy

The growth of low-end hardware has led to a proliferation of machine learning-based services in edge applications.

Token-Level Adversarial Prompt Detection Based on Perplexity Measures and Contextual Information

no code implementations20 Nov 2023 Zhengmian Hu, Gang Wu, Saayan Mitra, Ruiyi Zhang, Tong Sun, Heng Huang, Viswanathan Swaminathan

Our work aims to address this concern by introducing a novel approach to detecting adversarial prompts at a token level, leveraging the LLM's capability to predict the next token's probability.

Fast Heavy Inner Product Identification Between Weights and Inputs in Neural Network Training

no code implementations19 Nov 2023 Lianke Qin, Saayan Mitra, Zhao Song, Yuanyuan Yang, Tianyi Zhou

In this paper, we consider a heavy inner product identification problem, which generalizes the Light Bulb problem~(\cite{prr89}): Given two sets $A \subset \{-1,+1\}^d$ and $B \subset \{-1,+1\}^d$ with $|A|=|B| = n$, if there are exact $k$ pairs whose inner product passes a certain threshold, i. e., $\{(a_1, b_1), \cdots, (a_k, b_k)\} \subset A \times B$ such that $\forall i \in [k], \langle a_i, b_i \rangle \geq \rho \cdot d$, for a threshold $\rho \in (0, 1)$, the goal is to identify those $k$ heavy inner products.

Decentralized Personalized Online Federated Learning

no code implementations8 Nov 2023 Renzhi Wu, Saayan Mitra, Xiang Chen, Anup Rao

Therefore, we propose a new learning setting \textit{Decentralized Personalized Online Federated Learning} that considers all the three aspects at the same time.

ToolChain*: Efficient Action Space Navigation in Large Language Models with A* Search

no code implementations20 Oct 2023 Yuchen Zhuang, Xiang Chen, Tong Yu, Saayan Mitra, Victor Bursztyn, Ryan A. Rossi, Somdeb Sarkhel, Chao Zhang

It formulates the entire action space as a decision tree, where each node represents a possible API function call involved in a solution plan.

Privacy Aware Experiments without Cookies

no code implementations3 Nov 2022 Shiv Shankar, Ritwik Sinha, Saayan Mitra, Viswanathan Swaminathan, Sridhar Mahadevan, Moumita Sinha

We propose a two-stage experimental design, where the two brands only need to agree on high-level aggregate parameters of the experiment to test the alternate experiences.

DiPS: Differentiable Policy for Sketching in Recommender Systems

no code implementations8 Dec 2021 Aritra Ghosh, Saayan Mitra, Andrew Lan

In sequential recommender system applications, it is important to develop models that can capture users' evolving interest over time to successfully recommend future items that they are likely to interact with.

Optimal Bidding Strategy without Exploration in Real-time Bidding

no code implementations31 Mar 2020 Aritra Ghosh, Saayan Mitra, Somdeb Sarkhel, Viswanathan Swaminathan

Earlier works on optimal bidding strategy apply model-based batch reinforcement learning methods which can not generalize to unknown budget and time constraint.
