Joint space calibration data for dVRK Si

# Data for dVRK Si tool calibration Four joints (Joint 3, 4, 5 and 6) are calibrated. All data is .csv files. Each joint has 15 groups of data used for training and validating during training, stored in the folder "Si_Joint?". Testing set is stored in the folder "Test_dataset", with Joint index in their file names. For both training dataset and testing set, each file has two columns. (If it contains 3 columns, ignore the first column.) The first one is the commands given to the robot, which is the output of the network. The second one is the real joint angle measured corrosponding to the commands, which is the input of the network. All data in this data set is collected with the same permanent cautery spatula. Note: This is the raw dataset. Data cleanning is probably needed based on the usage.
