PREPROCESSING DATA FOR NEURAL NETWORKS By: Lou Mendelsohn Today's global markets demand new analytical tools for survival and profit as prevailing methods of analysis lose their luster. Here, STOCKS & COMMODITIES contributor Lou Mendelsohn explains how an emerging method of analysis -- synergistic market analysis -- can be applied to neural networks for financial forecasting and

It really depends on your neural network and what format your input data is in. Since neural networks take in numeric vectors as input (or a batch of vectors, i.e. a matrix), we normally need to convert the data into a numeric form. For the most g...

Therefore, among the others, normalization is one of the most important preprocessing tool for neural networks. So how to normalize the data? Min-Max Scaling. One of the commonly used techniques is using min-max scaling. It is very straightforward: \[\begin{equation} X_{i} ^{S} = \dfrac{X_i - X_{min}}{X_{max} - X_{min}} \end{equation}\]

Data Augmentation is one of the most widely used preprocessing strategy in Computer Vision Techniques. Deep Learning models need lot of data to make sure they are properly trained without overfitting or underfitting the train data. In the current data driven era, there is lot of raw data, but very small amount of data is really useful.

There are often considerations to reduce other dimensions, when the neural network performance is allowed to be invariant to that dimension, or to make the training problem more tractable. Data augmentation: Another common pre-processing technique involves augmenting the existing data-set with perturbed versions of the existing images.

the first open conference on neural networks was held and the International Neu-ral Network Society was formed [15]. Further more it was during the 1980’s that convolutional neural networks were developed. Today neural networks are widely used both by famous companies, such as Google and Facebook, and start up projects, such as SmartPlate.

I've come across an issue with my ANN when attempting to port my offline analysis to an online, real-time, application. I currently train my algorithm using an array of input data, number of channels (columns) against number of samples (rows), and I preprocess the data by subtracting the samples mean and dividing through the standard deviation.

To see this, suppose for example that y = 0 and a ≈ 0 for some input x. This is a case when the neuron is doing a good job on that input. We see that the first term in the expression (57) C = − 1 n ∑ x [ y ln a + ( 1 − y) ln ( 1 − a)] for the cost vanishes, since y = 0, while the second term is just − ln(1 − a) ≈ 0.
