Adjusted R square is a statistical measure that represents the proportion of variance in the dependent variable accounted for by the independent variables.
Adjusted R square is an extension of R square, which measures the goodness of fit of a regression model.
It takes into account the number of predictors in the model and adjusts for the degrees of freedom.
Adjusted R square ranges from 0 to 1, where a higher value indic...
Both Random Forest and XG Boost are powerful machine learning algorithms, but their performance depends on the specific problem and data.
Random Forest is an ensemble learning method that combines multiple decision trees to make predictions.
It is known for its ability to handle high-dimensional data and maintain good performance even with noisy or missing data.
XG Boost, on the other hand, is a gradient boosting algorith...
Max pooling is a pooling operation that selects the maximum value from a region of the input data.
Max pooling is commonly used in convolutional neural networks (CNNs) for feature extraction.
It reduces the spatial dimensions of the input data while retaining the most important features.
Max pooling helps in achieving translation invariance, making the model more robust to variations in input position.
For example, in a 2x...
