Key Machine Learning Models:
Some of the commonly used ML models for supply chain forecasting are;
1. Time series model:
Time series forecasting models use historical data to build patterns and trends over time. Examples include:
- ARIMA (Autoregressive Integrated Moving Average): A statistical model that combines autoregression, differencing, and moving average.
- Prophet: This Facebook model has been mainly built to handle seasonality and holidays.
2. Regression Models:
In such models, a continuous output variable is predicted depending on one or more input variables. Examples include:
- Linear regression: A simple model that suggests a linear relationship between the input and output variables.
- Multiple Linear Regression: An extended linear regression that acknowledges various inputs.
3. Neural Networks:
As the human brain inspires these models, they can learn complex patterns from big data. For example:
- Recurrent Neural Networks (RNNs): Generally relevant for time series data and have “memories” to retain an earlier point in time.
- Long-Short-Term Memory (LSTM): This is a type of RNN that can handle a long-term dependency inside the data.
4. Tree-Based Models:
These models formulate predictions by creating a tree-like structure. Some examples are:
- Decision Trees: They are simple models where decisions are made based on a chain of if-then rules.
- Random Random Forest: An ensemble method that combines different decision trees for better accuracy and overfitting reduction.
