Supervised Machine Learning

 

Supervised learning is something in which there is input and output variables are provided. They are labelled for organisation to provide a learning basis for future data processing. Supervised learning system provides the learning algorithms along with certain quantities to support future judgements. For this execution, mapping of function is done from input variable to output variable. So if in future a new input variable is entered, it can map the output variable. The given image shows the process of supervised machine learning.

In this, different input attributes are present. It can be any kind of any type. It can be a value, a picture, a histogram or a discrete numbers.  For each and every input variable, there is an expected output. Same the output can also be discrete or a real number. Because of all these, the algorithms  works on the input and execute the output.

In this, once the algorithm gets upskilled, it can give the accurate output of the never observed input. Here, we have a supervisor who keeps on correcting the machine with the help of given output. It helps the machine in differentiating between two or more different types of input data and it keeps on replicating till we get the final and accurate output. Let’s take an example of a mobile. Once the mobile is deployed, it is ready to recognize any image.  

It is called as supervised learning because the decision is made from the process of algorithm from input dataset same as the teacher supervising the learning process and the learning terminates only when it reaches the level of the acceptable results.

 

 

Some of the popular  cases of Supervised Learning are -

1-      ‘Cortana’ which is a speech automation  instructs using a voice of a customer. It gets trained once and then works according to that instructions only. And then it performs every tasks according to their customer’s wish.

2-      Weather applications work on the basis of Supervised learning.  It requires some important knowledge like when the weather will be cloudy, the humidity level will be high and many more. This envisions the conditions for the given period of time.

3-      Biometric attendance is also an example of Supervise Machine Learning.  In this, a couple of inputs are given to machine and then in future the machine can identify the person.
