What is Machine Learning?

Machine learning is a subset of the field of artificial intelligence. Machine learning algorithms process large amounts of data in order to reveal patterns and make predictions about future events or outcomes.

The goal of machine learning is for computers to learn from existing information, without having been explicitly programmed what’s important. This allows AI programs to analyze new datasets as they come up.

Benefits of Machine Learning?

Data scientists can use machine learning to find hidden insights in data, which they may not have otherwise noticed. While humans are still better than machines at many tasks, computers don’t get tired or bored of looking for patterns and drawing conclusions from large amounts of information.

Different Types of Machine Learning

There are many different types of machine learning. These include supervised, unsupervised, and reinforcement algorithms.

Supervised Learning

Supervised machine learning is when computers learn from input data that has both expected outputs and the correct answer. For example, a computer might use supervised learning to tell if an email is spam or not based on its content

Unsupervised Learning

In this case, computers analyze unlabeled input data without instruction about what they should find within the information – often using clustering techniques such as KMeans algorithm

Reinforcement Machine Learning

Used by robots when deciding how best to navigate their environment based on trial and error feedback from sensors that measure variables like

Machine learning Model Building

An image is worth a thousand words.

Here is an image that explains the machine learning model-building process.

Machine Learning Real World Projects For Beginners

One way to get started with Machine learning is to do sample projects which are available online.

let’s look at some of the beginner’s level machine learning projects to get started with.

1. Object Recognition
2. Social Media Monitoring
3. Sentiment Analysis of Tweets

Object Recognition

Basically, this project is about extracting features from an input image and then making a classification of the type of object it represents. The algorithm used in this application is Support Vector Machines (SVM) which is one of the most popular machine learning algorithms for pattern recognition tasks such as Object Detection.

Sentiment Analysis of Tweets

This project deals with analyzing sentiment through tweets by applying human-readable rules that define what constitutes positive vs negative sentiments. To start off we need to select pre-trained word embeddings – WordNet lexical

Social Media Monitoring

This project is about extracting features from social media and then making a classification on the type of post-it represents.
