What type of neural networks were discussed in lecture one?
Fully connected
What happens when a two-dimensional image is fed into a fully connected network for image classification?
The spatial structure of the image is lost
Why is it mentioned that densely connected networks lose the spatial structure of images?
To emphasize the importance of spatial structure
What is a drawback of using densely connected neural networks for image processing?
Loss of spatial structure
In densely connected networks, what does it mean that every input is connected to every output in a layer?
High connectivity within the network
How does collapsing a two-dimensional image into a one-dimensional vector affect the subsequent processing?
Spatial information is lost
Learn about how images are represented as three-dimensional arrays of brightness values and the challenges that come with variations in occlusions, illumination, and intra-class differences. Discover how to build a classification pipeline that is invariant to these variations.
