We study in this paper how explicit user feedback can be used by a case-based reasoning system to improve the quality of its retrieval phase. More specifically, we explore how both ranking feedback and relevance feedback can be exploited to modify the weights of case features. We propose some options to cope with each type of feedback. We also evaluate, in an interactive setting, their impact on a travel scenario where some user provides feedback on a series of queries. Our results indicate… Expand

TLDR
This work studies the optimisation of similarity measures in tasks where the computation of similarities is not directly visible to end users, namely clustering and case-based recommenders and proposes to use the feedback in a way that incorporates machine learning for updating weights and decisions of knowledge engineers about possible additional features, based on insights derived from a summary of user feedbacks.

Learning measures of semi-additive behaviour
TLDR
This work proposes a small set of features for aggregation behaviour of measure values, and uses them in a case-based reasoning approach, where the system suggests an aggregation behaviour, with 86% accuracy in the collected dataset. Expand
Case-base maintenance of a personalised and adaptive CBR bolus insulin recommender system for type 1 diabetes
TLDR
The maintenance methodology presented in this paper deals with numerical recommendations and can manage a potentially huge case-base due to the combinatorial derived from the number of attributes used to represent a case. Expand
SIIP: A SITUATION ANALYSIS PROTOTYPE USING CASE-BASED REASONING AND LEARNING
TLDR
A prototype that supports the execution of the Intelligence Preparation of the Operational Environment (IPOE) and its reasoning processes, and the learning mechanisms used to improve the case-based reasoning are described. Expand

Learning Feature Weights from Case Order Feedback
TLDR
A new framework for learning similarity measures is presented, whose main advantage is its generality, because its application is not restricted to classification tasks in contrast to other already known algorithms. Expand
Using Introspective Learning to Improve Retrieval in CBR: A Case Study in Air Traffic Control
TLDR
This paper describes a comprehensive set of techniques for learning local feature weights and evaluates these techniques on a case-base for conflict resolution in air traffic control and shows how introspective learning of feature weights improves retrieval and how it can be used to determine context sensitive local weights.

TLDR
LCW’s estimate of the mean preferences of a customer population improved as the number of customers increased, even for larger numbers of features of widely differing importance, which led to improved prediction of individual customers’ rankings. Expand
Learning feature weights from customer return-set selections
This paper describes LCW, a procedure for learning customer preferences represented as feature weights by observing customers' selections from return sets. An empirical evaluation on simulatedExpand
A Review and Empirical Evaluation of Feature Weighting Methods for a Class of Lazy Learning Algorithms
TLDR
A class of weight-setting methods for lazy learning algorithms which use performance feedback to assign weight settings demonstrated three advantages over other methods: they require less pre-processing, perform better in the presence of interacting features, and generally require less training data to learn good settings.

Case-based recommender systems
TLDR
A framework in which these systems can be understood is defined, and a selection of papers from the case-based recommender systems literature is reviewed, covering the development of these systems over the last ten years. Expand
