Autoencoders exhibit encoder-decoder structure:
Autoencoders are used in supervised as well as unsupervised learning tasks. They can consist of convolution, dense or even recurrent layers. As the name suggests, they tend to encode their inputs in smaller dimensional space.
They are primarily used for dimensionality reduction and other tasks like image generation, segmentation, neural implanting etc.
LMS; perceptron converges to a solution to correctly categorize patterns, but its result is prone to noise since patterns are often close to decision boundaries. LMS tries to move the boundaries far from training patterns.
By approximating the p.i., we are limiting the expansion finitely because its derivatives exist.
The weights in the weight matrix that differentiate between the target outputs will change, such as if [1 -1 -1] is orange and [1 1 -1] is apple, the weight matrix will be [0 1 0]
