Data Science

Data science, also known as data-driven science, is an interdisciplinary field about scientific methods, processes, and systems to extract knowledge or insights from data in various forms, either structured or unstructured, similar to data mining.

9. Machine Learning

1. Linear Regression with one and multiple variables.

Linear regression predicts a real-valued output based on an input value. We discuss the application

of linear regression to housing price prediction, present the notion of a cost function, and introduce

the gradient descent method for learning. 

1. Cost function

2. Gradient descent

3. Normal Equations

1. Logistic regression. What if your input has more than one value? In this module, we show how

linear regression can be extended to accommodate multiple input features.

1. Cost Function

2. Gradient descent solution.

1. Neural Networks. Neural networks is a model inspired by how the brain works. It is widely used

today in many applications: when your phone interprets and understand your voice commands, it is

likely that a neural network is helping to understand your speech;

1. Back propagation

2. Application of Neural Network

1. Support Vector Machines (SVM). Support vector machines, or SVMs, is a machine learning

algorithm for classification. We introduce the idea and intuitions behind SVMs and discuss how to

use it in practice.
