The network that involves backward links from output to the input and hidden layers is called as ____.
a) Self organizing maps
b) Perceptrons
c) Recurrent neural network
d) Multi layered perceptron

Having multiple perceptrons can actually solve the XOR problem satisfactorily: this is because each perceptron can partition off a linear part of the space itself, and they can then combine their results.
a) True â€“ this works always, and these multiple perceptrons learn to classify even complex problems.
b) False â€“ perceptrons are mathematically incapable of solving linearly inseparable functions, no matter what you do
c) True â€“ perceptrons can do this but are unable to learn to do it â€“ they have to be explicitly hand-coded
d) False â€“ just having a single perceptron is enough

A perceptron adds up all the weighted inputs it receives, and if it exceeds a certain value, it outputs a 1, otherwise it just outputs a 0.
a) True
b) False
c) Sometimes â€“ it can also output intermediate values as well
d) Canâ€™t say

Neural Networks are complex ______________ with many parameters.
a) Linear Functions

. Why are linearly separable problems of interest of neural network researchers?
a) Because they are the only class of problem that network can solve successfully
b) Because they are the only class of problem that Perceptron can solve successfully
c) Because they are the only mathematical functions that are continue
d) Because they are the only mathematical functions you can draw

Â What is back propagation?
a) It is another name given to the curvy function in the perceptron
b) It is the transmission of error back through the network to adjust the inputs
c) It is the transmission of error back through the network to allow weights to be adjusted so that the network can learn.
d) None of the mentioned

Why is the XOR problem exceptionally interesting to neural network researchers?
a) Because it can be expressed in a way that allows you to use a neural network
b) Because it is complex binary operation that cannot be solved using neural networks
c) Because it can be solved by a single layer perceptron
d) Because it is the simplest linearly inseparable problem that exists.

I need a MATLAB source code to recognize different regular
geometric shapes
such as: squares,rectangles,triangles,circles and ellipses
in different sizes using neural network.
All of the images containing these shapes should be in
binary format with the size of 300*400 pixels.
would you please give me a MATLAB code to detect these
geometric shapes?
