#Pretraining

This project leverages the Mixtral-8x7B model, enhanced with an expanded Chinese vocabulary to improve NLP capabilities. It offers open-source access to both the expanded model and incremental pre-training code, which notably boosts encoding and decoding efficiency in Chinese, ensuring strong comprehension and generation potentials. Users should remain attentive to potential biases or inaccuracies in outputs. The model is compatible with various acceleration techniques within the Mixtral-8x7B ecosystem and can be downloaded including options for integrating LoRA weights.

Discover an informative guide for developers interested in understanding the core elements of large language models (LLMs). This tutorial covers the creation of a GPT-like model from scratch using PyTorch, with focus on data input pipelines, main architecture components, and pretraining techniques. It also includes instructions for loading and finetuning with pretrained weights via open-source libraries such as LitGPT. A convenient cloud setup is available for practical experimentation and smooth code execution.

Examine how human preferences are incorporated into language model pretraining via Hugging Face Transformers. This method uses annotations and feedback to align models with human values, enhancing their ability to reduce toxicity and meet compliance standards. Learn about methods, configurations, and available pretrained models for tasks including toxicity management, PII detection, and PEP8 adherence, documented using wandb. Leverage this codebase to refine models for better processing of language aligned with human expectations.

Life2vec explores the predictive nature of life-event sequences, applying advanced algorithms for modeling human behaviors. The project features essential implementations and scripts for data management, model training, and statistical analysis. Various components like class distance-weighted cross-entropy loss are available in separate repositories. Utilizing Hydra for configuration, life2vec ensures methodical experiment planning. The project's resources, compliant with Statistics Denmark's Research Scheme, support prediction tasks from mortality to emigration, optimized for PyTorch and PyTorch Lightning environments.
