Blocking time series split
WebJun 9, 2024 · While time blocking reduces the opportunity for context switching, task batching takes it a step further. With task batching, you group similar tasks and get them … WebFeb 15, 2024 · However, in time series there is a dependency between observations and it could lead to target leak in the estimation when k-fold CV is used. For Time Series data I explored the following cross-validation techniques: 1) Scikit-learn's Time Series Split. Here we use expanding window for the train set and a fixed-size window for the test data.
