 Here are some important parameters that we need to pass to the `fit` method:
 * `epochs`: Number of iterations over the data you want the training process to perform. Epoch = iteration. 
 * `batchSize`: How many examples will be used for updating model's parameters (aka weights and biases) at a time
-*  You can set `verbose` to `true` you want to monitor the training process for every batch, and `false` if you only want 
-to see updates per epoch.

-Here's what you can expect to see as the output during the training process:

 Once the model has been trained, it's important to evaluate its performance on the validation dataset, so that we can 
 check how it generalizes to the new data.
