On the ideal shortest vector problem over random rational primes

Yanbin Pan, Jun Xu, Nick Wadleigh +1

Any ideal in a number field can be factored into a product of prime ideals. In this paper we study the prime ideal shortest vector problem (SVP) in the ring …

SetRank: Learning a Permutation-Invariant Ranking Model for Information Retrieval

Liang Pang, Jun Xu, Qingyao Ai +3

In learning-to-rank for information retrieval, a ranking model is automatically learned from the data and then utilized to rank the sets of retrieved documents. Therefore, an ideal…

HAS-QA: Hierarchical Answer Spans Model for Open-domain Question Answering

Liang Pang, Yanyan Lan, Jiafeng Guo +3

This paper is concerned with open-domain question answering (i.e., OpenQA). Recently, some works have viewed this problem as a reading comprehension (RC) task, and directly applied…

Beyond Precision: A Study on Recall of Initial Retrieval with Neural Representations

Yan Xiao, Jiafeng Guo, Yixing Fan +3

Vocabulary mismatch is a central problem in information retrieval (IR), i.e., the relevant documents may not contain the same (symbolic) terms of the query. Recently, neural repres…

A Tree Search Algorithm for Sequence Labeling

Yadi Lao, Jun Xu, Yanyan Lan +3

In this paper we propose a novel reinforcement learning based model for sequence tagging, referred to as MM-Tag. Inspired by the success and methodology of the AlphaGo Zero, MM-Tag…
