Regression

Regression is a powerful statistical technique used to identify the relationship between variables—typically between an independent variable (predictor) and a dependent variable (outcome).

In the realm of machine learning, regression algorithms are applied to datasets to understand how the independent variables influence the dependent variable. This understanding allows us to predict unknown values based on the learned correlations.

Example: Imagine you have a dataset with employee salaries and their years of experience. By applying a regression model, you can establish a relationship between experience and salary, enabling you to predict the salary of employees based on their experience.

How Regression Works

Let’s explore a regression example with a dataset that records house prices (in dollars) against the area (in square meters) in the town of Branalle.

X-axis: Area (Independent Variable)
Y-axis: Price (Dependent Variable)

A regression model built on this data will determine the relationship between the area and price. The model's output will be a line on the graph (linear or nonlinear, depending on the algorithm used) that represents the predicted house prices based on their area.

This "prediction line" becomes the basis for forecasting unknown values, such as the price of a house with a given area.

Understanding Regression Tasks

Regression models generate continuous outputs, making them ideal for tasks where the outcome is a continuous variable. For example, if you need to predict house prices from a dataset, this is a regression task, as prices are continuous.

Types of Regression Models

There are several types of regression models used in machine learning, including:

  • Simple Linear Regression
  • Multiple Linear Regression
  • Polynomial Regression
  • Support Vector Regression
  • Decision Tree Regression
  • Random Forest Regression

In future posts, we'll dive deeper into these models and explore how to implement them using Python.

What is General adversarial networks?

Image
  Understanding General Adversarial Networks The world of artificial intelligence (AI) has seen a lot of amazing advancements in recent years. One of the most exciting developments in this field is the introduction of  Generative Adversarial Networks (GANs).  Invented by Ian Goodfellow and his team in 2014, GANs have quickly become one of the most popular techniques in machine learning. At its core, a GAN is a type of  neural network  that is made up of two separate and competing networks: a generator and a discriminator. The generator is responsible for creating artificial data that is similar to the real data it has been trained on. The discriminator, on the other hand, is tasked with distinguishing between the real data and the artificial data created by the generator. The two networks engage in a continuous feedback loop, with the generator trying to improve its ability to create more realistic data while the discriminator tries to improve its ability to id...
