Try it now for free! In the world where risk-free assets like banking deposits have close to zero or even negative returns, investors are seeking for ways to save and grow their assets. We constantly improve them, try new models and new scientific approaches. We believe our model are more accurate than competitors have and our service is much easier to use by either novice or experienced traders.
By Devang Singh Introduction Machine learning has proved to improve efficiencies significantly, and there are many jobs which have been replaced by smarter and faster machines using artificial intelligence or machine learning.
The stock markets are no exceptions to this.
These algorithms often provide greater returns than other alternate algorithms or sometimes even higher than experienced traders. In this article, I will talk about the concepts involved in a neural network and how it can be applied to predict stock prices in the live markets.
Let us start by understanding what a neuron is. There are three components to a neuron, the dendrites, the axon and the main body of the neuron. The dendrites are the receivers of the signal and the axon is the transmitter.
Alone, a neuron is not of much use, but when it is connected to other neurons, it does several complicated computations and helps operate the most complicated machine on our planet, the human body.
A computer neuron is built in a similar manner, as shown in the diagram.
There are inputs to the neuron marked with yellow circles, and the neuron emits an output signal after some computation. The input layer resembles the dendrites of the neuron and the output signal is the axon.
Each input signal is assigned a weight, wi. This weight is multiplied by the input value and the neuron stores the weighted sum of all the input variables.
These weights are computed in the training phase of the neural network through concepts called gradient descent and back propagation, we will cover these topics in our subsequent blog posts on Neural Networks.
An activation function is then applied to the weighted sum, which results in the output signal of the neuron. The input signals are generated by other neurons, i. This is the basic idea of a neural network.
We will look at each of these concepts in more detail in this article. Working of Neural Networks We will look at an example to understand the working of neural networks. The input layer consists of the parameters that will help us arrive at an output value or make a prediction.

|Working Of Neural Networks For Stock Price Prediction||It has been shown that under certain circumstances, when hypotheses are drawn in this manner and averaged according to Bayes' law, this technique has an expected error that is bounded to be at most twice the expected error of the Bayes optimal classifier. Recent rigorous proofs demonstrate the accuracy of BMA in variable selection and estimation in high-dimensional settings,  and provide empirical evidence highlighting the role of sparsity-enforcing priors within the BMA in alleviating overfitting.|
Our brains essentially have five basic input parameters, which are our senses to touch, hear, see, smell and taste. The neurons in our brain create more complicated parameters such as emotions and feelings, from these basic input parameters. And our emotions and feelings, make us act or take decisions which is basically the output of the neural network of our brains.
Therefore, there are two layers of computations in this case before making a decision. The first layer takes in the five senses as inputs and results in emotions and feelings, which are the inputs to the next layer of computations, where the output is a decision or an action.

Though mathematical ideas underpin the study of neural networks, the author presents the fundamentals without the full mathematical apparatus. All aspects of the field are tackled.
Hence, in this extremely simplistic model of the working of the human brain, we have one input layer, two hidden layers, and one output layer. Of course from our experiences, we all know that the brain is much more complicated than this, but essentially this is how the computations are done in our brain.
To understand the working of a neural network, let us consider a simple stock price prediction example, where the OHLCV Open-High-Low-Close-Volume values are the input parameters, there is one hidden layer and the output consists of the prediction of the stock price.

There are five input parameters as shown in the diagram, the hidden layer consists of 3 neurons and the resultant in the output layer is the prediction for the stock price. The 3 neurons in the hidden layer will have different weights for each of the five input parameters and might have different activation functions, which will activate the input parameters according to various combinations of the inputs.
For example, the first neuron might be looking at the volume and the difference between the Close and the Open price and might be ignoring the High and Low prices.vetconnexx.com offers stock analysis with 5-days forecast, 1 and live comment powered by our proprietary Neural Network and Artificial Intelligence technologies.

I have implemented a narxnet neural network to predict the next day closing price of stocks. I have been conducting this experiment for Offshore Stocks on the Singapore Exchange.
The problem I am having is that Neural Network is giving extremely accurate results for prediction with Mean Absolute. The system also finds correlations between the pattern recognition methods and technical and fundamental methods results in order to find the direction of the market trend, to predict the next day price of a stock and to trigger a useful buy/sell signal.
