The learning rate is a hyperparameter that scales an update made by an iterative optimization algorithm. In machine learning, it is commonly written as η or α. For ordinary gradient descent, the update at iteration t is

KV cache offloading is the practice of moving part or all of a Transformer model's KV cache out of accelerator memory (GPU HBM) into a larger, slower tier such as CPU DRAM, local NVMe storage, or remote storage, and then bringing back, or recomputing

Calibration in machine learning is the property that the probability scores produced by a probabilistic classifier match the empirical frequency of the predicted event: a model that assigns a confidence of 0.8 to a set of inputs should be correct on about 80…
