Analysis of Evolutionary Behavior in Self-Learning Media Search Engines

no code implementations22 Nov 2019 Nikki Lijing Kuang, Clement H. C. Leung

In a SelfLearning Search Engine architecture, the subtle nuances of human perceptions and deep knowledge are taught and captured through unsupervised reinforcement learning, where the degree of reinforcement may be suitably calibrated.

Performance Dynamics and Termination Errors in Reinforcement Learning: A Unifying Perspective

no code implementations11 Feb 2019 Nikki Lijing Kuang, Clement H. C. Leung

A situation that often calls for learning termination is when the number of negative rewards exceeds the number of positive rewards.

Stochastic Reinforcement Learning

no code implementations11 Feb 2019 Nikki Lijing Kuang, Clement H. C. Leung, Vienne W. K. Sung

In reinforcement learning episodes, the rewards and punishments are often non-deterministic, and there are invariably stochastic elements governing the underlying situation.

Semantic Evolutionary Concept Distances for Effective Information Retrieval in Query Expansion

no code implementations19 Jan 2017 Valentina Franzoni, Yuanxi Li, Clement H. C. Leung, Alfredo Milani

In this work several semantic approaches to concept-based query expansion and reranking schemes are studied and compared with different ontology-based expansion methods in web document search and retrieval.
