Contextual Conservative Q-Learning for Offline Reinforcement Learning

no code implementations3 Jan 2023 Ke Jiang, Jiayu Yao, Xiaoyang Tan

In this paper, we propose Contextual Conservative Q-Learning(C-CQL) to learn a robustly reliable policy through the contextual information captured via an inverse dynamics model.

A Content-Based Approach to Email Triage Action Prediction: Exploration and Evaluation

no code implementations30 Apr 2019 Sudipto Mukherjee, Ke Jiang

Email has remained a principal form of communication among people, both in enterprise and social settings.

Revisiting Kernelized Locality-Sensitive Hashing for Improved Large-Scale Image Retrieval

no code implementations CVPR 2015 Ke Jiang, Qichao Que, Brian Kulis

We present a simple but powerful reinterpretation of kernelized locality-sensitive hashing (KLSH), a general and popular method developed in the vision community for performing approximate nearest-neighbor searches in an arbitrary reproducing kernel Hilbert space (RKHS).

Small-Variance Asymptotics for Hidden Markov Models

no code implementations NeurIPS 2013 Anirban Roychowdhury, Ke Jiang, Brian Kulis

Starting with the standard HMM, we first derive a “hard” inference algorithm analogous to k-means that arises when particular variances in the model tend to zero.

Small-Variance Asymptotics for Exponential Family Dirichlet Process Mixture Models

no code implementations NeurIPS 2012 Ke Jiang, Brian Kulis, Michael. I. Jordan

Links between probabilistic and non-probabilistic learning algorithms can arise by performing small-variance asymptotics, i. e., letting the variance of particular distributions in a graphical model go to zero.
