LLM分词器的构建方式有两种:一种是自己构造词表并训练一个分词器custom tokenizers,自己训练一个分词器的代码在generate_tokenizer 另一种是选择开源模型训练好的分词器,例如ChatGLM2-6B,Llama2等。本次使用ChatGLM2-6B的tokenizer预训练准备训练数据预训练数据推荐 MNBVC 地址:https://github.com/esbatmop/MNBVC ...

LLM などの最近の ML モデルはサイズが大きく、複雑なので、包括的なテストスイートでも十分に検証できない場合があります。モデルが想定どおりに動作しているかを確認する唯一の方法は、本番環境からメトリクスを収集、集約して、実際のパフォーマンスを観察することです。 CircleCI プラッ...
After deploying an ML model, you must set up production monitoring and performance analysis software. Due to the size and complexity of modern ML models such as LLMs, even a comprehensive test suite may fail to ensure their validity. The only way to determine that a model is performing as ...

Training a machine learning (ML) model is a process in which a machine learning algorithm is fed with data to learn from it to perform a specific task (e.g. classification) and finally have the…
An N-gram model predicts the most likely word to follow a sequence of N-1 words given a set of N-1 words. It's a probabilistic model that has been trained on a text corpus. Many NLP applications, such as speech recognition, machine translation, and predi
