Difference between regression and classification model?

The difference between regression and classification models lies in the type of output they predict. Lang

Regression

• Goal: Predict a continuous numeric value

• Example Outputs: Price, temperature, age, salary

• Algorithms Used:

  • Linear Regression

  • Decision Tree Regression

  • Random Forest Regressor

  • XGBoost Regressor

Example Question:

What will be the house price given the size and location?

Classification

• Goal: Predict a category or class label

• Example Outputs: Yes/No, Spam/Not Spam, Disease/No Disease

• Algorithms Used:

  • Logistic Regression

  • Decision Trees

  • Random Forest Classifier

  • SVM

  • XGBoost Classifier

Example Question:

Will this email be classified as spam or not?

European Union Digital Services Act (EU DSA) 2022

The Digital Services Act (DSA) is a regulation adopted by the European Union in 2022. It aims to create a safer and more accountable online environment by addressing issues such as illegal content, transparent advertising, and disinformation. Here are some key points:

• Consumer Protection: The DSA sets clear rules to protect consumers and their fundamental rights online. This includes measures to prevent the spread of illegal content and disinformation.
• Platform Accountability: Online platforms, including social networks, marketplaces, and content-sharing platforms, are required to take more responsibility for the content they host. This includes removing illegal content and being transparent about their content moderation decisions.
• Innovation and Growth: The DSA aims to foster innovation and competitiveness by providing a single set of rules across the EU, making it easier for smaller platforms, SMEs, and start-ups to scale up.
• User Control: Users will have more control over the content they see and will find it easier to report illegal content. There are also stronger protections for children, such as prohibiting targeted advertising to minors.

Overall, the DSA seeks to balance the roles of users, platforms, and public authorities, ensuring a fair and open online platform environment.
