What are the different types of machine learning?
Machine learning has brought a huge revolution in
today’s world. By using this amazing technology, ordinary computers are being
trained to become artificially intelligent. To make the machines acquire a myriad
of skills, they are programmed with certain types of machine learning.
SUPERVISED LEARNING-
This type of learning is mainly task-oriented and
improves the machine’s ability to give accurate responses. The computer is made
to solve certain problems and is supposed to give answers. Those answers are
compared to real answers and the computers are given feedback. The computers understand
the algorithm and recognize the pattern of analyzing questions and their
decision-making improves significantly. The ads we see while browsing through the
internet are achieved by supervised learning. The learning algorithm enables
the machine to place the ads that are popular and have more chances of being
clicked. The inappropriate mail automatically goes to the spam folder as a
result of supervised learning of certain algorithms. Whenever we post a picture
with our friends on Facebook, it recognizes the faces of our friends and
suggests tagging them in the photo. This ability of face recognition is
developed through supervised learning.
UNSUPERVISED LEARNING-
In this kind of learning, the machine is fed with huge
amounts of unlabeled data. The machine is supposed to organize and label the
humongous data in groups and clusters so that essential inference can be made from
it. The industries can understand the shopping habits of people by analyzing
the data through machines and can increase their productivity. YouTube recommendations of videos are based on
data of the people who share the same interests as us while watching a video
and unsupervised learning makes machines find a relationship in data patterns
and provides video suggestions according to it. Amazon shows us the products bought
by people having the same choices as us and increases its sale. The companies
use unsupervised learning to segregate customers and do targeted marketing. It
is also used to detect fraud in banking sectors. Nowadays, it is also being
used to predict the weather and climate of an area.
REINFORCEMENT LEARNING-
The machine is given rewards or a positive signal for working
according to the order given and is punished or given negative signals for disobeying
it. The algorithm is modified to accept the rewards and minimize mistakes. The machine
tries to find out different actions, performs them, compares the results and
learns to do the actions with the most reward points. The machine is made to
acquire certain skills like playing a video game. Robotics also uses this
learning to make robots efficient at doing tasks better. It is also being used
in the field of e-commerce and medicine. Reinforced learning is being used by
large companies to execute their trading and maximize their profit. It can be
used to make training systems that would provide study materials according to
the needs of the students.
