Hey everyone I have started studying about machine learning and decided to share my journey with you guys.
So today as it was my first day I got to know about the term Machine Learning and some of its fundamentals which I am sharing in this post.
What is Machine Learning?
Machine Learning is a branch of Artificial Intelligence that gives computers the ability to learn without explicitly being programmed.
It was defined in the 1950s by AI pioneer Arthur Samuel as “the field of study that gives computers the ability to learn without explicitly being programmed.”
Types of Machine Learning
Machine Learning is broadly categorized in 4 types ->
Supervised Machine Learning -> In supervised machine learning the data is labeled ,meaning each example comes with a correct answer ,and the machine is trained on this data and a model is generated which gives accurate prediction for similar kind of data. For example training the machine for a given set of pictures of trees, flowers, leaves etc. labeled properly and after getting perfectly trained when a new similar input is given machine makes a prediction.
Unsupervised Learning -> In unsupervised learning the data is not labeled the machine learns by identifying pattern in data. In an unsupervised learning process, the machine learning algorithm is left to interpret large data sets and address that data accordingly. The algorithm tries to organize that data in some way to describe its structure.
Reinforcement Learning -> Reinforcement machine learning trains machines through trial and error to take the best action by establishing a reward system. For example a robot is given some instructions ,whenever it takes a wrong decision it learns from it and for every right decision it is rewarded.
Semi Supervised Machine Learning -> Semi-supervised learning is similar to supervised learning, but instead uses both labelled and unlabeled data. In semi-supervised learning, the algorithm learns from a dataset that contains a small amount of labeled data and a much larger amount of unlabeled data.
Apart from theoretical part I learnt little about math’s part also which I’ll share in my next post till then stay connected 🙂
