Perplexity: A Key Metric for Evaluating Language Models

Perplexity is a key metric for evaluating the performance of Language Models (LMs), especially Large Language Models (LLMs), by measuring how well they predict text. A lower perplexity score indicates a model's greater accuracy and reduced uncertainty. This metric is vital for comparing different model architectures and training methods, and it is closely related to concepts like entropy, playing a significant role in Natural Language Processing and Machine Learning applications such as translation, text generation, and conversational AI. AI
