 we tested various heterogeneous learnware reuse methods (without using user's labeled data) and compared them to the user's self-trained model based on a small amount of training data.
 The average MSE performance across 41 users are as follows:

 From the results, it is noticeable that the learnware market still perform quite well even when users lack labeled data, 
 provided it includes learnwares addressing tasks that are similar but not identical to the user's.
