Feature-Level Attentive ICF for Recommendation
نویسندگان
چکیده
Item-based collaborative filtering (ICF) enjoys the advantages of high recommendation accuracy and ease in online penalization thus is favored by industrial recommender systems. ICF recommends items to a target user based on their similarities previously interacted user. Great progresses have been achieved for recent years applying advanced machine learning techniques (e.g., deep neural networks) learn item similarity from data. The early methods simply treat all historical equally recently proposed attempt distinguish different importance when recommending item. Despite progress, we argue that those models neglect diverse intents users adopting watching movie because director, leading actors, or visual effects). As result, they fail estimate finer-grained level predict user’s preference an item, resulting sub-optimal recommendation. In this work, propose general feature-level attention method models. key our factors computing prediction. To demonstrate effectiveness method, design light network integrate both item-level It model-agnostic easy-to-implement. We apply it two baseline evaluate its six public datasets. Extensive experiments show enhanced consistently outperform counterparts, demonstrating potential differentiating

Self-Attentive Feature-level Fusion for Multimodal Emotion Detection
Multimodal emotion recognition is the task of detecting emotions present in user-generated multimedia content. Such resources contain complementary information in multiple modalities. A stiff challenge often faced is the complexity associated with feature-level fusion of these heterogeneous modes. In this paper, we propose a new feature-level fusion method based on self-attention mechanism. We ...
متن کاملNAIS: Neural Attentive Item Similarity Model for Recommendation
Item-to-item collaborative filtering (aka. item-based CF) has been long used for building recommender systems in industrial settings, owing to its interpretability and efficiency in real-time personalization. It builds a user’s profile as her historically interacted items, recommending new items that are similar to the user’s profile. As such, the key to an item-based CF method is in the estima...
متن کاملConnotative Feature Extraction For Movie Recommendation
It is difficult to assess the emotions subject to the emotional responses to the content of the film by exploring the film connotative properties. Connotation is used to represent the emotions described by the audiovisual descriptors so that it predicts the emotional reaction of user. The connotative features can be used for the recommendation of movies. There are various methodologies for the ...
متن کاملRecurrent Coevolutionary Feature Embedding Processes for Recommendation
Recommender systems often use latent features to explain the behaviors of users and capture the properties of items. As users interact with different items over time, user and item features can influence each other, evolve and co-evolve over time. To accurately capture the fine grained nonlinear coevolution of these features, we propose a recurrent coevolutionary feature embedding process model...
متن کاملInterpretable Feature Recommendation for Signal Analytics
This paper presents an automated approach for interpretable feature recommendation for solving signal data analytics problems. Themethodhas been tested by performing experiments on datasets in the domain of prognostics where interpretation of features is considered very important. The proposed approach is based on Wide Learning architecture and provides means for interpretation of the recommend...
