Machine learning is a form of AI that enables a system to learn from data rather than through explicit programming. However, machine learning is not a simple process. As the algorithms ingest training data, it is then possible to produce more precise models based on that data. A machine-learning model is the output generated when you train your machine-learning algorithm with data. After training, when you provide a model with an input, you will be given an output.
Machine-learning algorithms use statistics to find patterns in large volumes of data. And data, here, encompasses a lot of things — numbers, words, images, clicks, what have you. If it can be digitally stored, it can be fed into a machine-learning algorithm.
Machine learning enables models to train on data sets before being deployed. Some machine- learning models are online and continuous. This iterative process of online models leads to an improvement in the types of associations made between data elements. Due to their complexity and size, these patterns and associations could have easily been overlooked by human observation. After a model has been trained, it can be used in real time to learn from data. The improvements in accuracy are a result of the training process and automation that are part of machine learning.
Machine learning is the process that powers many of the services we use today. Recommendation systems like those on Netflix, YouTube, and Spotify. search engines like Google and Baidu; social-media feeds like Facebook and Twitter. Voice assistants like Siri and Alexa.
Categories of machine learning
In supervised learning, the most prevalent, the data is labeled to tell the machine exactly what patterns it should look for. Supervised learning is intended to find patterns in data that can be applied to an analytics process. This data has labeled features that define the meaning of data.
In unsupervised learning, the data has no labels. The machine just looks for whatever patterns it can find. Unsupervised techniques aren’t as popular because they have less obvious applications.
A reinforcement algorithm learns by trial and error to achieve a clear objective. Reinforcement learning is a behavioral learning model. The algorithm receives feedback from the data analysis, guiding the user to the best outcome.
Deep learning is especially useful when you’re trying to learn patterns from unstructured data. Deep learning complex neural networks are designed to emulate how the human brain works, so computers can be trained to deal with poorly defined abstractions and problems.
Applications of Machine Leaning
Netflix Movie Recommendation: The algorithm that Netflix uses to recommend movies is nothing but Machine Learning. More than 80 percent of the shows and movies are discovered through the recommendation section.To recommend movies, it goes through threads within the content rather than relying on the genre board in order to make predictions.
Amazon Alexa: Alexa is the voice-controlled Amazon ‘personal assistant’ in Amazon Echo devices. Alexa can play music, provide information, deliver news and sports scores, tell you the weather, control your smart home, and even allow prime members to order products that they’ve ordered before.
Amazon Product Recommendation: I am sure that you might have noticed, while buying something online from Amazon, it recommends a set of items that are bought together or items that are often bought together, along with your ordered item.Have you ever wondered how does Amazon recommend you that? Well again, Amazon uses Machine Learning algorithm to do so
Google Maps: Google Maps anonymously sends real-time data from the Google Maps users on the same route back to Google. Google uses Machine Learning algorithm on these data to predict accurately the traffic on that route.
