Content-Based Cross-Domain Recommendations Using Segmented Models

چکیده
Cross-Domain Recommendation is a new field of study in the area of recommender systems. The goal of this type of recommender systems is to use information from other source domains to provide recommendations in target domains. In this work, we provide a generic framework for content-based cross-domain recommendations that can be used with various classifiers. In this framework, we propose an e cient method of feature augmentation to implement adaptation of domains. Instead of defining the notion of domain based on item descriptions, we introduce user-based domains. We define meta-data features as a set of features to characterize the fields that domains come from and introduce indicator features to segment users into di↵erent domains based on values of the meta-data features. We study an implementation of our framework based on logistic regression and perform experiments on a dataset from LinkedIn to perform job recommendations. Our results show promising performance in certain domains of the data.

Cross-Technique Mediation of User Models
Nowadays, personalization is considered a powerful approach for designing more precise and easy to use information search and recommendation tools. Since the quality of the personalization provided depends on the accuracy of the user models (UMs) managed by the system, it would be beneficial enriching these models through mediating partial UMs, built by other services. This paper proposes a cro...

Cross-domain recommender systems aim to generate or enhance personalized recommendations in a target domain by exploiting knowledge (mainly user preferences) from other source domains. Due to the heterogeneity of item characteristics across domains, content-based recommendation methods are difficult to apply, and collaborative filtering has become the most popular approach to cross-domain recom...

Newborn EEG Seizure Detection Based on Interspike Space Distribution in the Time-Frequency Domain
This paper presents a new time-frequency based EEG seizure detection method. This method uses the distribution of interspike intervals as a criterion for discriminating between seizure and nonseizure activities. To detect spikes in the EEG, the signal is mapped into the time-frequency domain. The high instantaneous energy of spikes is reflected as a localized energy in time-frequency domain. Hi...
