What is Machine Learning and its types?

We always wonder how Alexa plays our favorite music or album whenever we ask her to do so. This is because of the advancement in machine learning and artificial intelligence. Alexa just stores the most played songs in its database. It guesses the most loved songs through user inputs in the form of “skip a song,” “increase volume,” and others.

Machine learning is being used worldwide by giants like Facebook that suggests posts in our feed to the software in driverless cars. Machine learning enables computers to improve their experience from their past mistakes. Gaining a machine learning certification can help you in becoming an expert in the field.

Now let’s understand what exactly machine learning is.

Machine Learning

Machine learning is the field in which computers are programmed to act and think like humans. It involves building computer algorithms that have the ability to improve automatically from its past experience and mistakes. When new data are fed to these machines, they can learn, grow and develop by themselves.  To conclude, machine learning models can find useful information without even guiding them. They are built on mathematical algorithms that help them to learn from their past.

Machine learning has the ability to adapt new data through various iterations. ML application learns from previous transactions and uses a pattern recognition approach to give informed results. You should earn a machine learning certification to understand these concepts better.

Now, as we have a fair idea about machine learning, let us understand how it works.

How does Machine Learning work?

The first process is to feed the training data into specific algorithms. This anonymous data helps in making the machine learning algorithm more precise and efficient.

The algorithm is affected by this training data. However, to test the algorithm, new input data is fed and both the results are then checked. If the results are not expected, the algorithm is then re-trained until the correct output is obtained. This helps the algorithms to learn and improve their efficiency over time.

Types of Machine Learning

Machine learning is a very complicated term; that’s why it is divided into two main areas. These are supervised and unsupervised learning. Each one has a certain purpose and produces specific results and predictions by utilizing numerous forms of data.

Let’s know more about the two categories:

  • Supervised Learning

In this type of learning, known or labelled data is fed as training data. Since the data is known, the earning is supervised. This results in successful execution. Once the algorithm is trained based on this labelled data, unknown data can be def to get various responses.

  • Unsupervised Learning

The training is data is unknown or unlabeled in unsupervised learning. It means that the data has not been used anywhere and is totally a fresh one.  The data is unknown; hence, the input cannot be used to guide the algorithm. Such data is just used to train the algorithm to search for patterns that can give the desired result. It is the case in which algorithms try to break code like the enigma machine but without using the human mind.
