A Hybrid Solution For The Cold Start Problem In Recommendation

Abstract

Recommender systems are becoming more and more significant in today’s digital world and in the modern economy. They make a substantial contribution to company operations by offering tailored advice and decreasing overwhelm. Collaborative filtering, being popular in the domain of recommendation, is used to offer recommendations to attract the target audience based on the feedback of people with comparable interests. This method has some limitations, such as a cold-start issue, which makes the system less effective in anticipating unknown objects. We provide a hybrid deep-learning-based strategy centered on a method to enrich user and item profiles to address the cold-start issue in the recommendation process using a collaborative filtering approach. We employ pretrained deep learning models to produce rich user and item feature vectors that aid in the creation of useful suggestions and handling of user and item cold-start issues. The creation of more precise and tailored similarity matrices is made possible by adding metadata to the extracted features of the user and item. The results of the experiment demonstrate that in terms of precision and rate coverage, the proposed method performs better than the baseline techniques.

Research and Application of Edge Computing and Deep Learning in a Recommender System

“…Building upon this, they introduced the concept of the deep cooperative neural network (DeepCoNN). Wang et al [11], relying on deep crossing, proposed a deep and cross network (DCN) model for predicting travelers' advertisement click-through rates. The DCN model utilizes both deep and cross networks for input features, generating pertinent information for prediction.…”
