Optimizing the Autoencoder Strategy

What is the best value to use for threshold ? In the last section, we adopted based on our experience. However, is this the best value for ? Threshold , in this case, is not automatically optimized via the training procedure. It is just a static parameter external to the training algorithm. In KNIME Analytics Platform, it is also possible to optimize static parameters outside of the Learner nodes.

Optimizing Threshold

Threshold is defined on a separate subset of data, called the optimization set. There are two options here:

If an optimization set with labeled fraudulent transactions is available, the value of threshold is optimized against any accuracy measure for fraud detection.
If no labeled fraudulent transactions are available in the dataset, the value of threshold is defined as a high percentile of the reconstruction errors on the optimization set.

During the data preparation phase, we generated three data subsets...
