Application of Contrastive Learning Based on ResNet34 in Unsupervised Image Classification

2025

In response to the problems of insufficient labeled data and feature complexity in industrial scenarios, this paper proposes an unsupervised contrastive learning model framework based on ResNet34. This method combines the powerful feature extraction capability …

TELEVAL: A Dynamic Benchmark Designed for Spoken Language Models in Chinese Interactive Scenarios

2025 · arXiv (Cornell University)

Spoken language models (SLMs) have advanced rapidly in recent years, accompanied by a growing number of evaluation benchmarks. However, most existing benchmarks emphasize task completion and capability scaling, while remaining poorly aligned with how users …

A pareto-efficient algorithm for multiple objective optimization in e-commerce recommendation

2019

Recommendation with multiple objectives is an important but difficult problem, where the coherent difficulty lies in the possible conflicts between objectives. In this case, multi-objective optimization is expected to be Pareto efficient, where no single …
