For a proper test of the trained neural network, we splitted our samples by users (instead of using the 0.7 / 0.3 approach). Training data: User 0 = 498 samples User 1 = 510 samples User 2 = 504 samples User 3 = 524 samples Total of 2035 samples (1425 for training + 610 for validation)   Test data: User 4 = 261 samples User 5 = 261 samples   Total of 522 samples  This way, we can ensure that all test samples were collected at a different time (with new force/torque sensor calibration) and by different users than the training samples.
