Deep learning is recently one of the most developing methods in AI. It enables machine processing power to acquire, analyse, and learn in frames of the used model. The latest development is in the direction of stability and suitability of models, speeding up the recognition process and operating on portable devices. The real power of deep learning is the capability of algorithms to find patterns and logic in a vast amount of data. The more data we import, the better the results. Another benefit of using an artificial neural network is that it takes the input as an array of integers – a format so versatile that anything digital can be converted to it.
