DPO: Direct Preference Optimization New: in addition to the original DPO algorithm, this repo now supports 'conservative' DPO and IPO. For conservative DPO, you just need to additionally pass the parameter loss.label_smoothing=X for some X between 0 and 0.5 when performing DPO training (0 giv...

代码:github.com/eric-mitchel 太长不看版 本文提出直接偏好优化(Direct Preference Optimization, DPO)策略,绕过显式建模奖励模型和强化学习,直接通过偏好数据来对齐语言模型。 一、引言 大语言模型展现了强大的学习和推理能力。但由于预训练的过程是无监督的,实现对大语言模型输出的精确控制是很难的。精确控制大语言...

RQ2: Is the diversity optimization driven by the post-processing method equally effective for different types of recommender systems? How would these recommender systems perform, in terms of diversity and accuracy, if they were combined with the same diversification post-processing? • RQ3: What ...

(95.9%) human alignment). PDX SAMOSA-Tag had similar technical characteristics to mouse ESCs and the experiments involving OS152 cells (Supplementary Fig.16). Future optimization of cell enrichment, DNA damage repair and nuclei purification will probably permit higher per-sample coverage using lower ...
2). The suppression of DMN subregions seems to be a mechanism through which the brain moderates some internal activity so that the externally-oriented cognitive function can reach optimization (Anticevic et al., 2012). In contrast, the ACC is typically associated with monitoring action and ...
