Machine Learning is a new trending field these days and is an application of artificial intelligence. It uses certain statistical algorithms to make computers work in a certain way without being explicitly programmed. The algorithms receive an input value and predict an output for this by the use of certain statistical methods. The main aim of machine learning is to create intelligent machines which can think and work like human beings.
Requirements of creating good machine learning systems
So what is required for creating such intelligent systems? Following are the things required in creating such machine learning systems:
Data – Input data is required for predicting the output.
Algorithms – Machine Learning is dependent on certain statistical algorithms to determine data patterns.
Automation – It is the ability to make systems operate automatically.
Iteration – The complete process is an iterative i.e. repetition of the process.
Scalability – The capacity of the machine can be increased or decreased in size and scale.
Modeling – The models are created according to the demand by the process of modeling.
Methods of Machine Learning
The methods are classified into certain categories. These are:
Supervised Learning – In this method, input and output is provided to the computer along with feedback during the training. The accuracy of predictions by the computer during training is also analyzed. The main goal of this training is to make computers learn how to map input to the output.
Unsupervised Learning – In this case, no such training is provided leaving computers to find the output on its own. Unsupervised learning is mostly applied on transactional data. It is used in more complex tasks. It uses another approach of iteration known as deep learning to arrive at some conclusions.
Reinforcement Learning – This type of learning uses three components namely – agent, environment, action. An agent is the one that perceives its surroundings, an environment is the one with which an agent interacts and acts in that environment. The main goal in reinforcement learning is to find the best possible policy.
