2. Air Compressor Health State Dataset Features Repository
This dataset is a collection of feature matrices formed by analysisng aforementioned dataset in two domains i.e. frequency and time-frequency. Features represent the signal at a much lower dimension. In total there are 7 such matrices. More details please refer paper mentioned below.

3. AirCompressor Healthy and LIV State Cyclic Dataset
We took 8 different training datasets, i.e total 256 acoustic recordings for each state namely Healthy, LIV were taken over a long period of time. Collected dataset was analysed and features were extracted in two domains i.e. frequency and time-frequency. Features represent the signal at a much lower dimension. In total there are 7 such matrices. More details please refer paper mentioned below.

4. Drill Bit Dataset Repository
The entire experimentation was performed with 3-AxisCNC EMCO Concept Mill 105. HSS twist drill bit of diameter 9 mm was used for drilling holes in the work piece made of Mild steel. For extensive experimentation, given a drill bit state, for each pair of varying feed rates and cutting speed combinations, a single vibration recording of 8 seconds was taken. Feed rate was varied as 4 mm/min, 8 mm/min and 12 mm/min, and Cutting speed was varied as 160rpm, 170rpm, 180rpm, 190rpm and 200rpm; giving a total of 15 combination pairs.
