Which can help to prevent exploding gradients?

• Standardization

• Batch normalization

• Lowering the learning rate

• Standardization

___________ can help keep ReLU units from dying.

• Backpropagation

• Lowering the learning rate

• Batch normalization

• Standardization

• Updating the weights

Check the standard components of neural network.

• A set of nodes, analogous to neurons, organized in layers.

• A set of weights representing the connections between each neural network layer and the layer beneath it. The layer beneath may be another neural network layer, or some other kind of layer.

• A set of biases, one for each node.

• An activation function that transforms the output of each node in a layer. Different layers may have different activation functions.

• True

• False

An enormous data set with randomly sampled examples probably :

• does not contain redundant data

• tends not to carry much more predictive value than large batches

• has more predictive value than a medium size data set
