UnverifiedANN solutions trade a slight loss in accuracy for orders-of-magnitude improvements in retrieval speed, returning the most similar results in milliseconds even at scales of millions to billions of vectors.70% similarUnverifiedRecall is defined as the proportion of the returned Top-K results that truly belong to the set of true nearest neighbors.65% similarUnverifiedEvaluating backtested returns requires attention to risk-adjusted metrics such as the Sharpe ratio and maximum drawdown; a strategy with 30% annualized returns but a 60% maximum drawdown is inferior to one with 15% annualized returns but only a 10% drawdown.63% similarUnverifiedCache Hit Rate refers to the proportion of requests in which an AI model is able to reuse already-cached context (prompt prefixes) when processing requests; the higher the hit rate, the lower the API cost for the same workload.62% similar
