The blog post explores advanced techniques for training state-of-the-art transformer-based NLP models, emphasizing the importance of overcoming challenges such as high computational demands, training instability, and data scarcity. It highlights the role of transfer learning, allowing models to leverage pre-trained parameters from related tasks to improve performance on data-scarce tasks. The article discusses strategies to mitigate training instability, such as layerwise learning rate decay and reinitialization of model layers. Additionally, it covers the benefits of pretraining with both unlabeled and labeled data to bridge the gap between pretraining and fine-tuning. The concept of pseudo-labeling is introduced as a method to enhance model robustness by incorporating unlabeled data. The piece underscores the necessity of experiment tracking using tools like Neptune to effectively monitor, compare, and validate model training processes, thus aiding in the management of complex models with millions of parameters. Overall, the blog provides a comprehensive guide to optimizing NLP model training by integrating these techniques with robust tracking and analysis tools.
