Enhancing Character-Level Understanding in LLMs through Token Internal Structure Learning

1 code implementation26 Nov 2024 Zhu Xu, Zhiqiang Zhao, Zihan Zhang, Yuchi Liu, Quanwei Shen, Fei Liu, Yu Kuang

Tokenization techniques such as Byte-Pair Encoding (BPE) and Byte-Level BPE (BBPE) have significantly improved the computational efficiency and vocabulary representation stability of large language models (LLMs) by segmenting text into tokens.

We introduce Imagen 3, a latent diffusion model that generates high quality images from text prompts.

Assessing Model Generalization in Vicinity

1 code implementation13 Jun 2024 Yuchi Liu, Yifan Sun, Jingdong Wang, Liang Zheng

This paper evaluates the generalization ability of classification models on out-of-distribution test sets without depending on ground truth labels.

Towards Hierarchical Multi-Agent Workflows for Zero-Shot Prompt Optimization

1 code implementation30 May 2024 Yuchi Liu, Jaskirat Singh, Gaowen Liu, Ali Payani, Liang Zheng

Specifically, we include a hierarchy of LLMs, first constructing a prompt with precise instructions and accurate wording in a hierarchical manner, and then using this prompt to generate the final answer to the user query.

Optimizing Calibration by Gaining Aware of Prediction Correctness

1 code implementation19 Apr 2024 Yuchi Liu, Lei Wang, Yuli Zou, James Zou, Liang Zheng

For example, for a narrow misclassification, a calibrator trained by the CE loss often produces high confidence on the wrongly predicted class (e. g., a test sample is wrongly classified and its softmax score on the ground truth class is around 0. 4), which is undesirable.

Harm Amplification in Text-to-Image Models
