What is Machine Learning?

With the help of machine learning systems, we can examine data, learn from that data and make decisions. Machine learning involves algorithms and Machine learning library is a bundle of algorithms.

Where do we use machine learning in our day to day life? Let’s explore some examples to see the answer to this question.

Machine Learning Real Examples

Given below are some real examples of ML:

Example 1:

If you have used Netflix, then you must know that it recommends you some movies or shows for watching based on what you have watched earlier. Machine Learning is used for this recommendation and to select the data which matches your choice. It uses the earlier data.

Example 2:

The second example would be Facebook.

When you upload a photo on Facebook, it can recognize a person in that photo and suggest you, mutual friends. ML is used for these predictions. It uses data like your friend-list, photos available etc. and it makes predictions based on that.

Example 3:

The third example is Software, which shows how you will look when you get older. This image processing also uses machine learning.

All these are some examples, that help us to understand, how machine learning is used. ML is similar to AI up to some extent, however, there is a difference between the two. It is related to data mining.

How does Machine Learning Help us?

It helps through powerful processing.

With the help of machine learning, systems make better decisions, at a high speed and most of the times they are accurate. Using this technique is inexpensive and it can analyze large and complex data sets.

Types of Machine Learning

Enlisted below are the various types:

  • Supervised
  • Unsupervised
  • Reinforcement

Let’s see each type in detail along with an example.

#1) Supervised Machine Learning

Past data is used to make predictions in supervised machine learning.

Example of supervised machine learning is the spam filtering of emails. We all use Gmail, Yahoo, or Outlook. Machine learning algorithms are used for deciding which email is spam and which is not.

Based on the previous data like received emails, data that we use etc., the system makes predictions about an email as for whether it is a spam or not. These predictions may not be perfect, but they are accurate most of the times.

Classification and Regression are the ML algorithms that come under Supervised ML.

#2) Unsupervised Machine Learning

Unsupervised machine learning finds hidden patterns.

Earlier we saw the example of Facebook (Example 2). This is an example of unsupervised machine learning. Clustering and Association algorithms come under this type of machine learning.

#3) Reinforcement Machine Learning

Reinforcement machine learning is used for improving or increasing efficiency.

Let’s explore some examples of the above-mentioned algorithms.

  • Classification: Spam filtering of emails.
  • Regression: These algorithms also learn from the previous data like classification algorithms but it gives us the value as an output. Example: Weather forecast – as how much rain will be there?
  • Clustering: These algorithms use data and give output in the form of clusters of data. Example: Deciding the prices of house/land in a particular area (geographical location).
  • Association: When you buy products from shopping sites, the system recommends another set of products. Association algorithms are used for this recommendation

This is all about machine learning. Now let’s take a look at the top machine learning software.
