Practice: Convolutional Neural Networks
Q1. Given the syntax below, select the option that will best improve a CNN model that you are trying to fit. model.fit(x_train, y_train, batch_size=batch_size, epochs=100, validation_data=(x_test, y_test)) Remove the validation_data option. Increase the number of epochs to 100. Decrease the number of epochs to 50. Add shuffling, by adding “, shuffle=True” at the end.
Answer: Add shuffling, by adding “, shuffle=True” at the end.
Q2. Which of the following statements is TRUE about a kernel in a Convolutional Layer applied to an image? Kernels allow the convolutional layers to perform nonlinear transformations. Kernels detect local features in an image such as lines, corners, and edges. Kernels identify which channel in the input data contains the most information. Kernels ease computation by reducing the number of dimensions in an image that must be processed.
Answer: Kernels detect local features in an image such as lines, corners, and edges.
