Keras perplexity
Web25 jul. 2024 · This way, we can dynamically adjust the k based on the probability distribution. By setting p=0.9, if 90% of the probability mass is concentrated on the top 2 tokens, we can filter out the top 2 tokens to sample from. If instead the 90% is distributed over 10 tokens, it will similarly filter out the top 10 tokens to sample from. Web14 apr. 2024 · The main results are that larger models: 1 are more sample-efficient: they obtain better results (lower perplexity on the language modelling task, and higher BLEU score on the translation task) after fewer gradient steps; and 2 even after adjusting for wall-clock time, larger models train faster.

Web13 apr. 2024 · t-SNE(t-分布随机邻域嵌入)是一种基于流形学习的非线性降维算法,非常适用于将高维数据降维到2维或者3维,进行可视化观察。t-SNE被认为是效果最好的数据降维算法之一,缺点是计算复杂度高、占用内存大、降维速度比较慢。本任务的实践内容包括:1、 基于t-SNE算法实现Digits手写数字数据集的降维 ... WebAs per #304, add perplexity via forced-decoding of target tokens as a text-to-text metric for JSON tasks, which can be enabled or disabled at will in task.json.. It's quite a shocker that a basic decoding-strategy agnostic metric like perplexity is unsupported, while metrics that depend on the adopted decoding strategy (like BLEU, ROUGE, etc.) are supported.
