Abstract: A machine learning apparatus includes a memory storing instructions and a processor that implements the stored instructions to execute a plurality of tasks. The tasks include an obtaining task that obtains a mixture signal containing a first component and a second component, a first generating task that generates a first signal that emphasize the first component inputting a mixture signal to a neural network, a second generating task that generates a second signal by modifying the first signal, a calculating task that calculates an evaluation index from the second signal, and a training task that trains the neural network with the evaluation index.
