来自谷歌的工作,利用大规模的Ranking模型提升文本生成的表现。 1. Introduction 当前的文本生成模型存在“likelihood trap”的问题,具体而言,模型在使用贪心解码或者beam search时会以较大的概率生成枯燥或重复的文本。而其他truncated采样的方法如top-k, nucleus以及typical sampling,虽然可以缓解上述问题,但是会导致inconsist...
trained on the extensive PubMed dataset, and the Cohere (https://cohere.com) re-ranking model, designed for broader domain applications. As shown in Tab. 2, we find that MedCPT steadily outperforms the Cohere re-rank model on all datasets, highlighting the ...
We have conducted the experimentations for confirming the predictions and studying the features of the ranks. The results show that the proposed ranks are very impressive for the given problem since they consider the query/topic, the content of publication and the citations in the ranking model....
Along this line of research, this work aims to investigate the capacity of LLMs that act as the ranking model for recommender systems. We first formalize the recommendation problem as a conditional ranking task, considering sequential interaction histories as conditions and the items retrieved by ...
The implementation and application of large models have ushered in a critical milestone. The first batch of domestically produced large model products were approved yesterday to be open to the public, with 3 in Shanghai and 5 in Beijing taking the lead in launching them. This means that domesti...
Moonshot AI's flagship product, Kimi, has seen a surge in popularity since its launch. In January 2024, Kimi's intelligent assistant recorded over 1.42 million visits, ranking first among AI ChatBots products in large model startups, with a month-on-month increase of 94.1%. ...

This phenomenon is known as Position Bias, which can be mitigated through the use of bootstrapping. This involves randomly assigning candidate items to different positions and repeating the ranking task several times. Popularity Bias Another form of bias that affects LLM ranking...
为了提升大模型在text ranking任务上的效果,该论文提出多阶段的训练策略(multi-stage training strategy),主要包含预训练(pre-trainning)和微调(supervised fine-tuning)两个阶段,实验证明RankingGPT在多个公开数据集上都取得了较明显的效果提升。 实现细节:
