inputSize = 36;
numClasses = 10;
hiddenSizeL1 = 30; % Fist Hidden Layer Size
hiddenSizeL2 = 30; % Second Hidden Layer Size 
sparsityParam = 0.1; %Avarage activation of the hidden units
lambda = 3e-3;         % weight decay parameter for Regularization
beta = 3;              % weight of sparsity penalty term 
% Load the vibration data file. 
load('fea1.mat')
trainData =fea1';
trainLabels = [ones(25,1)];
% trainLabels(trainLabels == 0) = 10; % Remap 0 to 10 since our labels need to start from 1
% Training the First Sparse Autoencoder
%  Randomly initialize the parameters
sae1Theta = initializeParameters(hiddenSizeL1, inputSize);
