Abstract: Highlights•Demonstrating the usage of model's outputs for overfitting or noise detection.•Retrieving a near-optimal co-training model without using a validation set.•Mostly co-training results cannot be improved further after a number of iterations.•Co-training has greater effect in transfer learning (TL) than in non-TL scenarios.
