Summary

This lecture, part of a course on mathematical methods for text analysis, focuses on efficient inference techniques for large language models. The instructor begins by defining key metrics for measuring computational and memory efficiency, such as FLOPs, model FLOPs utilization, memory bandwidth utilization, and latency metrics like time-to-first-token and inter-token latency. He distinguishes between the prefill and decode phases, highlighting that prefill is compute-bound while decode is memory-bound. The lecture then covers three main optimization methods: knowledge distillation, quantization, and speculative decoding. Knowledge distillation is explained in detail, including hard vs. soft labels, offline vs. online, and on-policy vs. off-policy variants. Quantization is introduced with symmetric and asymmetric methods, and the challenges of calibrating activation ranges are discussed. The lecture also touches on post-training quantization and quantization-aware training. The instructor emphasizes the importance of balancing compute and memory utilization for optimal performance.
