ARIMA (AutoRegressive Integrated Moving Average) is a popular algorithm for time series forecasting.
A learning curve plots training and validation performance to diagnose issues like overfitting or underfitting.
Principal Component Analysis (PCA) reduces multicollinearity by transforming correlated features into uncorrelated components.
Isolation Forest is an algorithm designed to detect anomalies by isolating outliers in the data.
The sigmoid function maps any real-valued number into a probability between 0 and 1, often used in binary classification.
Data Augmentation creates modified versions of training data to increase dataset size and diversity.
Ensemble methods combine predictions from multiple models to improve overall performance and robustness.
Recurrent Neural Networks (RNNs) can suffer from the vanishing gradient problem during backpropagation.
Batch normalization normalizes the inputs to a layer, stabilizing and accelerating training.
The bias term shifts the activation function, allowing better fitting of the data by the model.
