Deep reinforcement learning has achieved successes on numerous tasks such as computer games, the game of Go, robotics, etc. Structured prediction aims at modeling highly dependent variables, which applies to a wide range of domains such as natural language processing, computer vision, computational biology, etc. In many cases, structured prediction can be viewed as a sequential decision making process, so a natural question is can we leverage the advances in deep RL to improve structured prediction?
Recently, promising results have been shown applying RL to various structured prediction problems such as dialogue (Li et al, 2016; Williams et al, 2017; He et al, 2017), program synthesis (Bunel et al, 2018; Liang et al, 2018), semantic parsing (Liang et al, 2017), architecture search (Zoph & Le, 2017), chunking and parsing (Sharaf & Daumé III 2018), machine translation (Ranzato et al, 2015; Norouzi et al, 2016; Bahdanau et al, 2016), summarization (Paulus et al, 2017), image caption (Rennie et al, 2017), knowledge graph reasoning (Xiong et al, 2017), query rewriting (Nogueira et al, 2017; Buck et al, 2017) and information extraction (Narasimhan et al, 2016; Qin et al, 2018). However, there are also negative results where RL is not efficient enough comparing to alternative approaches (Guu et al, 2017; Bender et al, 2018; Xu et al, 2018). As a community it is very important to figure out the limit and future directions of RL in structured prediction.
This workshop will bring together experts in structured predictions and reinforcement learning. Specifically, it will provide an overview of existing approaches from various domains to distill generally applicable principles from their successes. We will also discuss the main challenges arising in this setting and outline potential directions for future progress. The target audience consists of researchers and practitioners in this areas. They include, but are not limited to, deep RL for:
