Supervised learning: A paradigm in machine learning in which algorithms learn the relationships between input data and outcomes we aim to model, where the algorithm is able to predict outcomes based on new input data. A good example here would be a credit scoring model algorithm, which, when ...

plt.subplots()creates an empty plotpxin the system, whilefigsize=(7.5, 7.5)decides the x and y length of the output window. An equal x and y value will display your plot on a perfectly squared window. px.matshowis used to fill our confusion matrix in the empty plot, whereas thecmap=...
In TensorFlow it can be computed as simple as,# An energy spectrogram is the magnitude of the complex-valued STFT. # A float32 Tensor of shape [batch_size, ?, 513]. magnitude_spectrograms = tf.abs(stfts) We can plot the energy spectrogram, and we can spot some pattern shown at the...
