Your ML Model Does Not Understand Dates: Cheap Timestamp Transforms That Boost Accuracy
dima806_dima · x · 2026-11-10
Dima Iakubovskyi's Medium article "Your ML Model Does Not Understand Dates" argues that most tabular models fail to properly exploit datetime features.
He shows how a sine-cosine pair, decomposed timestamps, and a couple of other cheap transforms can move accuracy as much as far more expensive approaches — practical feature engineering for anyone working with tabular or time-series data.
