Global Forest Change dataset covers 2000-2024
The dataset's creation relied on the opening of the Landsat archive and cloud-based computation, allowing it to evolve from a one-time publication into a maintained data series. This evolution signifies the dataset's ongoing relevance and adaptability to new research needs.
Example
A researcher studying deforestation trends can use the Global Forest Change dataset to analyze tree-cover loss and gain from 2000 to 2024, leveraging its detailed and consistent annual records.
Understanding when to use cross-validation is crucial for obtaining reliable estimates, especially when dealing with small datasets. Cross-validation helps mitigate overfitting and provides a more accurate assessment of model performance.
to use random forests: when you want a strong baseline with minimal hyperparameter tuning
Random forests are ideal for robust baseline models with minimal hyperparameter tuning
Boosting (machine learning)
Boosting reduces bias in ML models
cross-entropy equals negative log-likelihood for classification
Cross-entropy measures the difference between predicted probabilities and true labels, thus it equals negative log-likelihood, reflecting the cost of incorrect predictions
log-loss / cross-entropy loss penalizes: confident wrong predictions more heavily
Log-loss penalizes confident incorrect predictions more heavily
