What Is Machine Learning And How Does IT Work?
Machine learning is a data analytics process that trains computers to do what comes naturally to humans and animals: learn from experience. Machine learning algorithms use computational methods to “learn” information directly from data without depending on a predetermined equation as a model.
WHY MACHINE LEARNING MATTERS
With the increase in big data, machine learning has become the chief technique for solving problems in various areas, such as:
- Computational finance, for credit scoring and algorithmic trading
- Image processing and computer vision, for motion detection, face recognition, and object detection
- Computational biology, drug discovery, for tumor detection and DNA sequencing
- Energy production, for load forecasting and price.
- Automotive, manufacturing and aerospace for predictive maintenance
- Natural language processing for voice recognition applications

HOW DOES MACHINE LEARNING WORKS:
This machine learning can be broken up into three different steps:
- Clean the data
- Pre-processing
- Testing
The initial step is you require to clean the data and format data that’s your pre-processing which mean computers now aren’t too smart when it comes to thinking out the difference between a text or picture when you send it in so the initial thing you do is generally clean the data so that all your pictures are in one file and your text is being processed individually and that’s all part of the pre-processing if you try to do process text like you do a picture you’re not going to get the correct answer and vice-versa.
Once you have processed the data and you have it nicely cleaned then learning to take that data and learn from it and there’s what they call unsupervised and supervised data. The third field is testing, once you have gone through all these processes now you have to train your learning so it works perfectly you need to test it making sure you get the right answers out of it once you have gone through all that then move to phase two which is really using it or putting it into commercial use and that is to do a prediction and on there here you have to train the model.
MACHINE LEARNING METHODS
Machine learning algorithms are often categorized as supervised or unsupervised.
- Supervised machine learning algorithms can implement what has been learned in the past to current data using labeled examples to predict future results.
- In distinction, unsupervised machine learning algorithms are applied when the information used to train is neither classified nor labeled. Unsupervised learning studies how systems can indicate a function to describe a hidden structure from unlabeled data.
- Semi-supervised machine learning algorithms fall somewhere in between the above two learning because they use both labeled and unlabeled data for training – typically a small amount of labeled data and a massive amount of unlabeled data.
- Reinforcement machine learning algorithms are a learning process that interacts with its environment by creating actions and discovers errors or rewards. Trial and error search and delayed reward are the most important characteristics of reinforcement learning.
Machine learning allows the analysis of massive quantities of data. While it usually delivers faster, more reliable results in order to identify beneficial opportunities or dangerous risks, it may also need additional time and resources to train it properly.
