Do Large Language Models have a "Reasoning Gap"?

The Irregular Voice • 2 HN points • 01 Apr 24
🕹 Technology AI Data Machine Learning Experiments Mathematics
  1. Large Language Models (LLMs) may not always exhibit true reasoning abilities, with a potential reliance on memorization instead of learning general techniques.
  2. Synthetic data generation systems like MATH() can be used to explore the reasoning capabilities of LLMs, but may introduce biases if not carefully analyzed and corrected for errors.
  3. Fine-tuning LLMs on specific problem areas can reveal insights into their reasoning abilities, but challenges with longer solutions and complex problem sets may impact performance.
