How do dense neural networks connect input pixels to neurons in the hidden layer?
How do dense neural networks connect input pixels to neurons in the hidden layer?
- By connecting only regions of the input image to a single neuron
- By connecting every input pixel to a single neuron (correct)
- By connecting patches of the input to a single neuron
- By connecting every single pixel to every single neuron
Why is it not feasible to connect every single pixel in the input to every single neuron in the hidden layer?
Why is it not feasible to connect every single pixel in the input to every single neuron in the hidden layer?
- Because it leads to overfitting
- Because it lacks spatial structure
- Due to the lack of computational power
- Due to the large dataset size (correct)
