Neural3.1 Neural Networks: Neural networks are loosely modelled on the networks of neurons in biological systems. They can learn to perform complex tasks. They are especially effective at recognizing patterns, classifying data, and processing noisy signals. They possess a distributed associative memory which gives it the ability to learn and generalize, i.e., adapt with experience. Electroencephalography (EEG) is a device which records each and every single activity of the brain through electrical signals which is sent by the nerve cells of brain. They record each and every pattern and image of all neural connections and sends back to the computer via the chip.
