The human brain is especially good at solving problems… So good, in fact, that in the 1940s various computer scientists began to build computation models in an attempt to replicate it. The Artificial Neural Networks (ANNs) that they created are responsible for major advancements in machine learning. By using nodes to imitate biological neurons, ANNs mimic the process of information exchange within our brains and provide the framework for algorithms to function. ANNs are used to find patterns in input data that humans might not detect due to complexity or volume. As data grows at an unprecedented rate, this has become all the more important.
