Usage demonstration :
Defination of the network :
>>> [num_layers, psizes, y, biases, weights ] = init([7,5,1])

This will create a 3 layer network with 7 nodes in the input layer, 5 nodes in the hidden layer and 1 node in the output layer.Also returned are the various variables related to the network created including random biases, weights etc. How to unlock honda radio code free calculator generator online free radio code kostenlos.
Import your data using any of the many methods and store in the
training_data
and test_data
.Do something like >>> [training_data, test_data] = xlsread(data.xls)
Finally, for training use this :
>>> SGD(training_data,test_data, epochs=100, eta_SGD=0.5)

Techniques Used with Neural Networks
Common machine learning techniques for designing neural network applications include supervised and unsupervised learning, classification, regression, pattern recognition, and clustering.
Supervised Learning
Supervised neural networks are trained to produce desired outputs in response to sample inputs, making them particularly well suited for modeling and controlling dynamic systems, classifying noisy data, and predicting future events. Deep Learning Toolbox™ includes four types of supervised networks: feedforward, radial basis, dynamic, and learning vector quantization.
Classification
Classification is a type of supervised machine learning in which an algorithm “learns” to classify new observations from examples of labeled data.
Regression
Regression models describe the relationship between a response (output) variable and one or more predictor (input) variables.
Pattern Recognition

Pattern recognition is an important component of neural network applications in computer vision, radar processing, speech recognition, and text classification. It works by classifying input data into objects or classes based on key features, using either supervised or unsupervised classification.
For example, in computer vision, supervised pattern recognition techniques are used for optical character recognition (OCR), face detection, face recognition, object detection, and object classification. In image processing and computer vision, unsupervised pattern recognition techniques are used for object detection and image segmentation.
Unsupervised Learning
Unsupervised neural networks are trained by letting the neural network continually adjust itself to new inputs. They are used to draw inferences from data sets consisting of input data without labeled responses. You can use them to discover natural distributions, categories, and category relationships within data.
Deep Learning Toolbox includes two types unsupervised networks: competitive layers and self-organizing maps.
Clustering

Clustering is an unsupervised learning approach in which neural networks can be used for exploratory data analysis to find hidden patterns or groupings in data. This process involves grouping data by similarity. Applications for cluster analysis include gene sequence analysis, market research, and object recognition.
