Image re-ranking is effective in improving performance of text-based image searches. However, improvements from existing algorithms are limited by two factors: one that the associated textual information images often mismatches their actual visual contents; other a visual's features cannot accurately describe semantic similarities between images.

Factorization Machine (FM) is an effective solution for context-aware recommender systems (CARS) which models second-order feature interactions by inner product. However, it insufficient to capture high-order and nonlinear interaction signals. While several recent efforts have enhanced FM with neural networks, they assume the embedding dimensions are independent from each other model in a rather implicit manner. In this paper, we propose Convolutional (CFM) address above limitations....

Click-through rate (CTR) prediction has become increasingly indispensable for various Internet applications. Traditional CTR models convert the multi-field categorical data into ID features via one-hot encoding, and extract collaborative signals among features. Such a paradigm suffers from problem of semantic information loss. Another line research explores potential pretrained language (PLMs) by converting input textual sentences through hard prompt templates. Although are preserved, they...

With the explosive growth of commercial applications recommender systems, multi-scenario recommendation (MSR) has attracted considerable attention, which utilizes data from multiple domains to improve their performance simultaneously. However, training a unified deep system (DRS) may not explicitly comprehend commonality and difference among domains, whereas an individual model for each domain neglects global information incurs high computation costs. Likewise, fine-tuning on is inefficient,...
