A lot of people want to learn Machine learning these days, but what are the best resources for learning it? There are thousands of online courses to choose from but many of them do not explain the crucial concepts and still charge high fees. 

Therefore, here is the list of the best free Machine Learning courses that cover the principles of Machine Learning from the scratch and goes up to an advanced level.

Key Takeaways

  • Machine Learning is a process in which machines are capable of detecting patterns and making decisions with minimal human intervention.
  • Explore various free Machine Learning courses online that cover core concepts from the ground up.
  • Machine Learning is used in technologies such as image recognition, speech recognition, self-driving cars, stock market trading and many more. 

What is Machine Learning?

Machine Learning is a branch of Artificial Intelligence (AI) and Computer Science which focuses on the use of data and algorithms to imitate the way that humans learn, gradually improving its accuracy.

Systems use the data to recognize patterns and make decisions with minimal human intervention. 

One popular example of Machine Learning is image detection. When the systems are given a lot of information about a certain image, it starts to identify the details and patterns.

It can distinguish between a human and a car. It can identify facial expressions and a lot more. This technology enables many Apps like Snapchat filters, Phone’s Face ID. Self-driving cars like Tesla use this technology to identify things on the road.

Image detection is a great feature of Machine Learning

Benefits of Machine Learning

The benefits of Machine Learning are countless. There are always some new innovations in the world around Machine learning. Following are few examples :

  • Google’s Deep Learning Machine Learning program is accurate 89% of the time in detecting breast cancer. That’s much more effective compared to pathologists at 74%. (Google)
  • The accuracy of the Azure Machine Learning framework in predicting stock market highs and lows is 62%. (Microsoft)
  • The accuracy of Google AI’s Machine Learning algorithm in predicting a patients’ death is 95%. (Bloomberg)

These are just the tip of the iceberg. Machine Learning has way more implications and therefore the demand for the stream is on the rise. 

Let’s talk about the growth of this industry lately and what we should expect.

The growth of the Machine learning Industry

Let us talk about numbers here. The Machine Learning market is expected to grow from USD 1.03 Billion in 2016 to USD 8.81 Billion by 2022, at a Compound Annual Growth Rate (CAGR) of 44.1% during the forecast period.

According to Google Trends, the search interest in the world of Machine learning has gone from 25 to 100 in 2020.  

The demand for Machine Learning engineers is increasing exponentially. Many new and old companies are changing the way they operate, and hence Machine learning experts are in high demand. Choosing this career can be both interesting and lucrative.
