Sample Keras Assessments question Test your knowledge!

Which Keras function can be used to save the architecture of a model as a JSON file?

  • model.to_json()
  • model.save_json()
  • model.export_json()
  • model.jsonify()
  • model.architecture_to_json()

Which Keras callback allows you to automatically adjust the learning rate during training?

  • ModelCheckpoint
  • EarlyStopping
  • ReduceLROnPlateau
  • CustomCallback
  • LearningRateScheduler

In Keras, what is the typical purpose of the `Sequential` model?

  • To execute non-linear graph of layers
  • To compile and train a neural network
  • To stack layers in a linear pipeline
  • To train models sequentially one after another
  • To initialize the weights of a neural network

When leveraging Keras's `ImageDataGenerator`, which transformation can be applied to augment training images?

  • Normalization only
  • Random rotations and flipping
  • Conversion to grayscale only
  • Sub-pixel shifting
  • Image distortion for creating new classes

Which component is NOT part of the Keras functional API?

  • Input
  • Layers
  • Model
  • Sequential
  • Tensor

In a Keras model, how is the `evaluate()` function different from the `predict()` function?

  • `evaluate()` trains the model, while `predict()` does not
  • `evaluate()` computes the loss and metrics, `predict()` generates output predictions
  • `predict()` can be used during training, `evaluate()` cannot
  • There is no difference; they are interchangeable
  • `evaluate()` is only used for regression tasks, while `predict()` is only for classification
