Lifelong and Continual Learning Dialogue Systems

no code implementations12 Nov 2022 Sahisnu Mazumder, Bing Liu

This book introduces the new paradigm of lifelong learning dialogue systems to endow chatbots the ability to learn continually by themselves through their own self-initiated interactions with their users and working environments to improve themselves.

Semantic Novelty Detection and Characterization in Factual Text Involving Named Entities

1 code implementation31 Oct 2022 Nianzu Ma, Sahisnu Mazumder, Alexander Politowicz, Bing Liu, Eric Robertson, Scott Grigsby

Much of the existing work on text novelty detection has been studied at the topic level, i. e., identifying whether the topic of a document or a sentence is novel or not.

Knowledge-Guided Exploration in Deep Reinforcement Learning

no code implementations26 Oct 2022 Sahisnu Mazumder, Bing Liu, Shuai Wang, Yingxuan Zhu, Xiaotian Yin, Lifeng Liu, Jian Li

This paper proposes a new method to drastically speed up deep reinforcement learning (deep RL) training for problems that have the property of state-action permissibility (SAP).

AI Autonomy : Self-Initiated Open-World Continual Learning and Adaptation

no code implementations17 Mar 2022 Bing Liu, Sahisnu Mazumder, Eric Robertson, Scott Grigsby

As more and more AI agents are used in practice, it is time to think about how to make these agents fully autonomous so that they can (1) learn by themselves continually in a self-motivated and self-initiated manner rather than being retrained offline periodically on the initiation of human engineers and (2) accommodate or adapt to unexpected or novel circumstances.

Self-Initiated Open World Learning for Autonomous AI Agents

no code implementations21 Oct 2021 Bing Liu, Eric Robertson, Scott Grigsby, Sahisnu Mazumder

As more and more AI agents are used in practice, it is time to think about how to make these agents fully autonomous so that they can learn by themselves in a self-motivated and self-supervised manner rather than being retrained periodically on the initiation of human engineers using expanded training data.

A Knowledge-Driven Approach to Classifying Object and Attribute Coreferences in Opinion Mining

no code implementations Findings of the Association for Computational Linguistics 2020 Jiahua Chen, Shuai Wang, Sahisnu Mazumder, Bing Liu

Classifying and resolving coreferences of objects (e. g., product names) and attributes (e. g., product aspects) in opinionated reviews is crucial for improving the opinion mining performance.

Lifelong Learning Dialogue Systems: Chatbots that Self-Learn On the Job

no code implementations22 Sep 2020 Bing Liu, Sahisnu Mazumder

Due to the huge amount of manual effort involved, they are difficult to scale and also tend to produce many errors ought to their limited ability to understand natural language and the limited knowledge in their KBs.

Building an Application Independent Natural Language Interface

no code implementations30 Oct 2019 Sahisnu Mazumder, Bing Liu, Shuai Wang, Sepideh Esmaeilpour

Traditional approaches to building natural language (NL) interfaces typically use a semantic parser to parse the user command and convert it to a logical form, which is then translated to an executable action in an application.

Lifelong and Interactive Learning of Factual Knowledge in Dialogues

no code implementations WS 2019 Sahisnu Mazumder, Bing Liu, Shuai Wang, Nianzu Ma

Dialogue systems are increasingly using knowledge bases (KBs) storing real-world facts to help generate quality responses.

Guided Exploration in Deep Reinforcement Learning

no code implementations27 Sep 2018 Sahisnu Mazumder, Bing Liu, Shuai Wang, Yingxuan Zhu, Xiaotian Yin, Lifeng Liu, Jian Li, Yongbing Huang

This paper proposes a new method to drastically speed up deep reinforcement learning (deep RL) training for problems that have the property of \textit{state-action permissibility} (SAP).

Towards a Continuous Knowledge Learning Engine for Chatbots

no code implementations16 Feb 2018 Sahisnu Mazumder, Nianzu Ma, Bing Liu

We model the task as an open-world knowledge base completion problem and propose a novel technique called lifelong interactive learning and inference (LiLi) to solve it.

Context-aware Path Ranking for Knowledge Base Completion

no code implementations20 Dec 2017 Sahisnu Mazumder, Bing Liu

PR algorithms enumerate paths between entity pairs in a KB and use those paths as features to train a model for missing fact prediction.
