Recently, DeepSeek-R1 has challenged the traditional view tha…
The scaling law of Large Language Models (LLMs) reveals a power-law relationship, showing diminishing return on performance as model scale increases. While training LLMs from scratch is resource-intensive, fine-tuning a pre-trained model for specific tasks has become a practical alternative. Full fi…
Large Language Models (LLMs) have demonstrated strong performance in open-ended generation tasks.
