 What is Machine Learning ?

• Machines learn from their past experiences and machines follow instructions given by humans but what if humans can train the machines to learn from the past data and do what humans can do and much faster well that's called machine learning but it's a lot more than just learning it's also about understanding and reasoning so today we will learn about the basics of machine learning. 

• supervised learning uses labeled data to train the machine and then there is reinforcement learning which is a reward based learning or we can say that it works on the principle of feedback to generalize machine learning model. The learning with unlabeled data is unsupervised learning so we saw supervised learning where the data was labeled. Siri asks how is machine learning possible in today's era well that's because today we have humongous data available everybody is online either making a transaction or just surfing the internet. 

• There are a lot of applications of machine learning out there to name a few machine learning is used in healthcare where diagnostics are predicted for doctor's review and fraud detection in the finance sector.
