It is required to distinguish between the characters E, H and O each represented on a 5 x 3 grid in the following diagrams

X X X X X X X X

The crosses above might not turn out right in the actual bid posting but they represent letters E,H and [url removed, login to view] perfect representation of each character would be a vector of length 15 with entries either 0 or 1. Thus the representation for E would be (1,1,1, 1,0,0, 1,1,1, 1,0,0, 1,1,1), for H would be (1,0,1, 1,0,1, 1,1,1, 1,0,1, 1,0,1) and for O would be (1,1,1, 1,0,1, 1,0,1, 1,0,1, 1,1,1). In practice there is noise and the scanner that provides these numbers typically provides a number x for a pixel with 0 £x £1. Thus the vextor corresponding to E might be

**(1.0,0.9,0.8, 0.9,0.3,0.0, 1.0,1.0,0.8, 0.7,0.2,0.5, 1.0,0.4,0.9)

**[url removed, login to view] a program, Java, which simulates a feedforward neural network with hidden layers and which is capable of being trained using the ideas ob backpropagation. Neurons should have the sigmoidal activation function. Thus if a neuron has m inputs y1,…., ymthen the neuron is determined by the value of the *m* weights w1,…., wmand the bias *b*; the summation block is s = y1w1 +…+ymwm+b And the output of the sigmoidal neuron *z* is given by z = 1/(1 + e-s) Weights and Bias should be initially random numbers between 0 and 1. The training rate coefficient, ŋ, should be able to vary.**

## Deliverables

1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.

2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables):

a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment.

b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request.

3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased.
