NASA PHM数据集相关

做数据挖掘的朋友们都知道，数据是研究的基本，获得一份有权威的原始数据是科学实验成功的前提。而NASA作为世界顶端的机构，他们的数据用来做PHM的研究所得出的结果肯定是具有非凡的说服力度的，在这里有想跟大家交流一下下喽！这里的15个数据集：

1、Algae Raceway Data Set（滚道数据集）

数据描述：

Experiments were conducted on 3 small raceways in which spirulina was inoculated. The growth and, ultimately, decline of the algae biomass was recorded along with a number of environmental parameters. Experiments were conducted by the Exobiology group at NASA Ames.

2、CFRP Composites Data Set（碳纤维复合材料数据集）

数据描述：

Run-to-failure experiments were run on CFRP panels with periodic measurements to capture internal damage growth under tension-tension fatigue. Monitoring data consist of lamb wave signals from a network of 16 piezoelectric (PZT) sensors and multiple triaxial strain gages. Additionally, periodic x-rays were taken to characterize internal damage as ground truth information. Three different layups were tested. Experiments were conducted at Stanford Structures and Composites Laboratory (SACL) in collaboration with the Prognostic Center of Excellence (PCoE) of NASA Ames Research Center.

数据格式：

Dataset is organized into three zipped folders each containing data from coupons of single layup type and includes a readme file, and a folder with reports and papers published from this dataset.

7、PHM08 Challenge Data Set（PHM08 挑战赛数据集）

数据描述

Data from the data challenge competition held at the 1st international conference on Prognostics and Health Management (PHM08) is being made publicly available. The dataset is similar to the one posted above (see Turbofan engine degradation simulation data set) except the true RUL values are not revealed. Users are expected to develop their algorithms using training and test sets provided in the package. The data set was provided by the Prognostics CoE at NASA Ames.

Note:
- Results should be formatted as a column vector of RULs in a text file.
- Evaluation of the test data is limited to only one trial per day.
- Best test score result still stands at 436.84 (but note that good performance in the test score does not guarantee good performance on the validation set - the person with the best test score ranked 22nd on the validation set).
- Best score on the validation set stands at 5636.06 (as stated in the readme file, you need to submit your RUL vector to the email indicated in the document)
- See Ramasso et al. for a comparison of approaches and leader scores.
