00:00.000 --> 00:11.000
In this video, we will understand how machines can learn from data.

00:11.000 --> 00:20.000
Learn how to train a model and make predictions using Python.

00:20.000 --> 00:29.000
Have you ever wondered how your mobile phone can take a picture and recognize objects, guide you with maps or even suggest the next video to watch?

00:29.000 --> 00:36.000
The answer is machine learning, a way for devices to learn from data and make smart decisions.

00:36.000 --> 00:41.000
In machine learning, building models, we use special libraries.

00:41.000 --> 00:44.000
The most popular in Python is sick at learn.

00:44.000 --> 00:50.000
It helps us train models with just a few lines of code and the workflow has clear steps.

00:50.000 --> 00:57.000
Collect data, preprocess it, choose an algorithm, train the model and finally test it.

00:57.000 --> 00:59.000
Let's say we want to predict student marks.

00:59.000 --> 01:06.000
We load a data set, choose a regression algorithm and use psychic learns fit method to train the model.

01:06.000 --> 01:10.000
Once trained, the model can make predictions using the predict method.

01:10.000 --> 01:15.000
For example, a 16 year old student might score 68 marks.
