Abstract

Recommending cold items is a long-standing challenge for collaborative filtering models because these cold items lack historical user interactions to model their collaborative features. The gap between the content of cold items and their behavior patterns makes it difficult to generate accurate behavioral embeddings for cold items. Existing cold-start models use mapping functions to generate fake behavioral embeddings based on the content feature of cold items. However, these generated embeddings have significant differences from the real behavioral embeddings, leading to a negative impact on cold recommendation performance. To address this challenge, we propose an LLM Interaction Simulator (LLM-InS) to model users' behavior patterns based on the content aspect. This simulator allows recommender systems to simulate vivid interactions for each cold item and transform them from cold to warm items directly. Specifically, we outline the designing and training process of a tailored LLM-simulator that can simulate the behavioral patterns of users and items. Additionally, we introduce an efficient "filtering-and-refining" approach to take full advantage of the simulation power of the LLMs. Finally, we propose an updating method to update the embeddings of the items. we unified trains for both cold and warm items within a recommender model based on the simulated and real interactions. Extensive experiments using real behavioral embeddings demonstrate that our proposed model, LLM-InS, outperforms nine state-of-the-art cold-start methods and three LLM models in cold-start item recommendations., Comment: Under review

Abstract

Yes-associated protein (YAP) and a transcriptional co-activator with PDZ-binding motif (TAZ) genes are crucial for regulating the size of mammalian tissues and organs as well as for many biological processes such as bone formation, cell lineage determination, tissue regeneration, and cell proliferation. The purpose of this study was to characterize the YAP and TAZ gene polymorphisms in 266 Guanzhong Dairy Goats and 299 Shanbei White Cashmere Goats and to explore their potential relationship with growth characteristics such as body weight and body length. After genotyping and using PCR amplification and Sanger sequencing to find polymorphisms in the YAP and TAZ genes, five InDels loci were found in the goat YAP gene and three InDels loci in the TAZ gene. The findings of the association analysis demonstrated that the goats' body weight, height, cannon circumference, chest depth, chest breadth, and chest circumference were all substantially influenced by five InDels loci in the YAP gene (p<0.05). Goat body height, trunk breadth, trunk length, body length, and body weight were all substantially impacted by three InDels loci in the TAZ gene (p<0.05). In conclusion, eight InDels loci of goat YAP and TAZ were found in this study, and their impacts on goat phenotype were disclosed. These results might offer fresh avenues for boosting goat molecular breeding. [ABSTRACT FROM AUTHOR]
