Memorization
In machine learning theory, the behavior whereby a learner remembers samples from the training set, that is, a sample incorporated into training can still be correctly predicted at test time or can influence the model's output.

A team successfully reduced the CPU cost of eBPF by approximately 90% by introducing memoization technology
Memoization is a strategy of caching the results of expensive function calls and returning the cached value directly when the same input appears again, trading space for time
In eBPF, a caching layer is typically introduced by using an eBPF map as a key-value store to implement memoization and avoid repeated processing of identical inputs
For highly random, nearly non-repeating inputs, memoization caching instead introduces additional overhead
If cached data can change (such as when a process exits or a connection closes), there must be a corresponding invalidation mechanism; otherwise stale results will be returned
Research shows that under certain conditions (such as a particular piece of text appearing at very high frequency in training data), models may reproduce verbatim content from training data, and in 2023 researchers from Google DeepMind and the University of California, Berkeley successfully extracted original fragments of training data from ChatGPT.
