Local minima in training of neural networks

Witryna6. Conclusion In this paper, we propose a novel method for training neural networks for the specific task of classifying medical images as normal or abnormal. Our proposed method shows great promise for this task, but also has an ease of implementation that allows for quick training of neural networks for general classification problem.
