Alteryx predictive tools flowchart
https://community.alteryx.com/t5/Data-Science/Alteryx-Predictive-Tools-Flowchart/ba-p/602881
- Investigate and prepare data for analysis • Identify suitable variables for predicting a target variable • Select predictor variables that fit given criteria • Create training and validation datasets • Select appropriate algorithms to model datasets • Train models • Compare models • Interpret model reports • Score new data with trained models • Classification • Regression • Time series • Optimization
Note:
- Arima/ETS can specify the starting period
- logistic regression tool must have only 2 values for target variables
- Optimization tool:
- Manual input:
- objective: function to minimize/ optimize
- constraint: constraint of the function of variable
- Bound: range of possible value of the variable
- O anchor (listed vertically), [”variable”] [”coefficient”]
- • The order of variables for input O and input A must be the same.
- Display field mapping for input anchor to map the field
- variable for the objective function (no inequality because we always want to optimize the coefficient)
- A anchor (constraint matrix using the combination of variables from O anchor)
- Constraints in rows (preferred): one row one constraint, [var1] [var..] [”dir”] [”rhs”]
- Variables in rows: one row one var (need dir & rhs as input B) [’variable’] [factor]
- maximize Onjective?: default to be minimize if this option is not ticked
- Manual input:
