+ | ====What do you mean ‘Learning by itself’ ?==== | ||
+ | We educate computers by providing them with numerous instances of queries and solutions. | ||
+ | We offer computers samples of questions and answers without instructing them on how to get the proper answers. The machine tries to find out a way to estimate the correct answer using the samples. Even if it hasn't encountered this exact question in the examples we've shown it, it learns to make an accurate estimate. The machine looks for similar questions it's seen before and makes a prediction based on the right answer it's seen before. That's all the computer is doing: guessing based on prior experience. | ||

+ | ===“Guessing you say, that's it? “Yes and No.==== | ||
+ | All the machine is doing is guessing based on previous experiences with similar queries. (Prediction is a fancy way of meaning guessing.) It's not like you're guessing at random. It tries to learn to make the best prediction possible based on some interesting arithmetic (which we won't go into right now). To summarize, Machine Learning is all about figuring out how to make the best estimate possible. The closest approach to the correct answer is the best potential guess. | ||
+ | ===“So how does it guess correctly? | ||
+ | At first, the machine makes some extremely bad estimates (starting with random guesses). The program then compares its own guess to the right answer given in the example. We instruct the computer to make fewer predictions and make them more accurate. It then travels on a merry-go-round in an attempt to cut down on errors. It self-corrects as it strives to lessen its errors, bringing it closer to the correct guess. | ||
+ | Experts refer to the process through which the computer corrects its own errors as gradient descent. There' | ||
