Artificial Intelligence (A.I) is a field of study which involves in making the computers think and take actions like humans. These actions include recognizing a familiar face, understanding the natural style of speaking, understanding a bad handwriting and many such cognitive tasks. The field is becoming more and more relevant right now. I highly recommend my readers to invest their time to learn about this field.
If you are planning to know more, please start with Machine Learning, Machine Learning involves various statistical methods to understand the data, get insights and make predictions from it. There are basically three categories of machine learning algorithms. Which are : Supervised Learning, Unsupervised Learning and Reinforcement Learning. Please check out the Machine Learning Tutorial form my website. You can access it from below links.
Once you have basic understanding of Machine Learning, you can take up Deep Learning tutorial which is more popular right now because it involves neural networks (a mathematical model of human brain) in solving some of the tough problems. Deep Learning right now is giving best results in Speech Recognition, Fraud Detection, Facial Recognition, Sentiment Analysis, Self Driving Cars and many such cool things.
