Neural Network Applications

From what I understand neural network applications are an artificial way for technology to predict, simulate, perform functions such as playing chess, recognizing patterns as seen in facial recognition, or something as practical as email spam filtering in which people use everyday without even realizing it. One real word example would be sales forecasting, this lets a company know what to expect about a product or their whole line of products future sales. This is a very popular application that has shown to be very useful for companies. Another example would be risk management which will show the risks that a company might have when investing in another company, product, or just from a change day-to-day operations.
