tiny-N-CMAPSS
收藏资源简介:
tiny-N-CMAPSS是2021年PHM数据挑战赛数据集的一个小型版本,它是N-CMAPSS数据集的一个子集。数据集中的传感器读数从双精度浮点数转换为半精度浮点数,时间序列数据采样率降低了100倍(从1Hz降至0.01Hz)。训练集包含多个文件,测试集则是比赛用的测试/验证集。
tiny-N-CMAPSS is a compact subset of the original N-CMAPSS dataset, serving as a miniaturized variant of the dataset used in the 2021 PHM Data Challenge. All sensor readings in the dataset have been converted from double-precision floating-point numbers to half-precision floating-point numbers, and the sampling rate of the time-series data has been downsampled by a factor of 100, dropping from 1Hz to 0.01Hz. The training set consists of multiple data files, while the test set is the official test/validation set provided for the competition.
