Overview
Machine Learning model performance degrades over time and the drift associated with data is one of the main reasons for the gradual drop in model accuracy. Drift Detection in Categorical variables aids in finding the extent of drift observed in data with respect to a reference dataset. The solution helps in identifying the features causing model’s accuracy loss and choosing a suitable interval to retrain the models.
Highlights
- This solution enables users to pinpoint the categorical features causing degradation in model performance. This can be leveraged to find out the features with drift between the training data and the production data.
- This solution uses multiple statistical metrics to measure the distance between reference data and evaluation data.
- PACE - ML is Mphasis Framework and Methodology for end-to-end machine learning development and deployment. PACE-ML enables organizations to improve the quality & reliability of the machine learning solutions in production and helps automate, scale, and monitor them.
