tiny-N-CMAPSS

tiny-N-CMAPSS is a small‑scale version of the 2021 PHM Data Challenge dataset, a subset of the N-CMAPSS dataset. Sensor readings in the dataset have been converted from double‑precision to half‑precision floating‑point numbers, and the time‑series sampling rate has been reduced by a factor of 100 (from 1 Hz to 0.01 Hz). The training set consists of multiple files, while the test set is the competition’s test/validation set.
