O1 LIGO Gravitational Wave Dataset

该数据集包含了来自高级LIGO第一次观测运行（O1）的标注时间序列数据，这些数据是从2015年9月至12月期间汉福德和利文斯顿探测器收集的。数据集共有6667条记录，标注了22种不同瞬态噪声类别。值得注意的是，该数据集极度不平衡，包含8个特征和1个标签，用于训练和预测。这些特征包括GPStime（全球定位时间）、peakFreq（峰值频率）、snr（信噪比）、centralFreq（中心频率）、duration（持续时间）、bandwidth（带宽）、id（标识）以及ifo（干涉仪数据）。规模上，数据集包含6667条记录，分为22个类别。该数据集的任务是进行异常检测。

This dataset contains annotated time-series data from the first observing run (O1) of Advanced LIGO, collected by the Hanford and Livingston detectors between September and December 2015. It consists of 6667 records annotated with 22 distinct transient noise categories, and the dataset is extremely imbalanced. It includes 8 features and 1 label for training and prediction purposes. The specific features are as follows: GPStime (Global Positioning System time), peakFreq (peak frequency), snr (signal-to-noise ratio), centralFreq (central frequency), duration, bandwidth, id (identifier), and ifo (interferometer data). The core task of this dataset is anomaly detection.
