    Study Notes

    Flattening Input for Fully Connected Layer

    • Given an input with size 8×8×64, when flattened, the output size will be 4096.
    • This is because the input dimensions are multiplied together to get the total number of elements.

    CNN Filter Characteristics

    • A CNN filter with a size of 5×5×3×10 produces 10 activation maps.
    • The filter size is broken down into height (5), width (5), channels (3), and number of filters (10).
    • Each filter generates a separate activation map, resulting in 10 maps.
