--Overview--
Dataset containing all Volatile Organic Compound sensor data and ripeness stage labels for tests 3 & 4 only.

###############################################
--Contents--

/VOC_x_test.csv:
CSV file containing cleaned data from the Figaro TGS2620 & TGS2602, and Sensiron SGP40 sensors for tests 3 & 4 for ML testing purposes.
This file contains 30% of all recorded data and is class balanced.
A header row is included. The first column is the index column and does not have a header.
Each row represents an instantaneous reading of the Figaro TGS2620 & TGS2602, and Sensiron SGP40 sensors at a point in time and is given
a unique index number in the index column. The index number corresponds to the labels in VOC_y_test.csv.
The header row titles are defined at the bottom of this ReadMe.

/VOC_x_train.csv:
CSV file containing cleaned data from the Figaro TGS2620 & TGS2602, and Sensiron SGP40 sensors for tests 3 & 4 for ML training purposes.
This file contains the 70% of all recorded data NOT present in VOC_x_test.csv, and is class balanced.
A header row is included. The first column is the index column and does not have a header.

/VOC_y_test.csv:
CSV file containing the labels for data from tests 3 & 4 for ML testing purposes.
The labels in this file correspond to the data in VOC_x_test.csv and are class balanced.
Two columns are included. An unlabelled index column and the label column, where the labels are integer values from 1 to 5
corresponding to ripeness stages for each instantaneous sensor reading.
Please refer to the associated publication for explanations of the ripeness stages and how they are derived.
