Fundamental concepts in Machine Learning!!

Just like normal conversation , we can start here!

There are two ladies conversing with each other on machine learning concepts, one lady name is Sharada and another is Swetha.

so conversation starts like this ,

swetha: hey sharada, Good morning, hope you had tight sleep yesterday.

sharada: yeah I did! but before that was reading the concepts of Machine Learning.

swetha: oh that’s great, What’s the main Idea ? can you summarize all of machine learning in a single sentences!?

sharada: Sure,Machine Learning is the collection of tools and technique that transforms the data into hopefully good decisions by making classifications like whether or not someone will love a movie or quantitative prediction, like how tall some is!

swetha: are you saying that machine learning is all about two things 1.)we can use it classify things and 2.) we can use it to make quantitative predictions?

sharada: that’s right swetha! , we can use machine learning to classify the things , we can call it classification. and when we do quantitative prediction we can call it as Regression.

sharada: so let’s talk about how machine learning is used for classification.

1. The Problem here is we have a big pile of data, we have to use it to make classifications.
2. for example , we meet this person and want to classify them as some someone who will like Swetha or not.!
3. We can use our data to built a classification Tree to classify a person as someone who will like Swetha or not.

• Ones the classification Tree is built, we can use it to make classifications by starting at top and asking the question, “Are you interested in machine Learning”
• if you are not interested in machine learning then go towards right (No)
• and now, Do you like “silly songs ?”
• if no , if you are not interested in machine learning and don’t like Silly Songs , then bummer!!
• on the other hand , if you like “silly songs “, then classification tree predicts that you are like Swetha!!
• and if you are interested in machine learning, then the classification Tree predicts that you will like Swetha!!
