Study Notes
- Predictions involving AI often use mathematical formulas, especially regression.
- Regression is about using mathematics to make predictions based on known data.
- Cross tabs and Scatter Plots are key topics covered in making predictions using mathematics.
- Supervised learning in AI includes classification and regression models.
- Regression is based on finding the most accurate prediction using known data inputs.
- Correlation is often used in conjunction with regression to understand the relationship between variables.
- Regression lines can point upwards, downwards, or show no correlation at all.
- Positive correlation means variables increase together, negative correlation means they move in opposite directions.
- Cross tabs help analyze the relationship between different variables in a structured manner.
- Pearson's R coefficient is used to measure the strength and direction of the correlation between variables.
- The formula for Pearson's R involves calculating mean values and deviations for each variable.
