Overview
Data evolves over time, causing a change in the distributions and interpretation of data and a corresponding degradation in model performance. The Drift Detector uses an incremental learning method, in which each incoming instance retrains the model. The solution detects drifts in the model output, providing useful insights with respect to the data and model behavior. This helps businesses identify degradation in model performance and need for retraining.
Highlights
- This solution takes in a time-series dataset as input, applies an incremental learning approach and performs drift detection. The result generated is the instances at which drift occur over time, as well as the output of the prediction model.
- A prediction model is incrementally retrained with incoming instances.
- 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.

Inputs
- Summary
Input:
Following are the mandatory inputs guidelines: • The algorithm works with a time-series dataset with a row limit of not less than 100 instances and not more than 14000 instances. • Supported content types: 'text/csv'. • Input must contain the columns ‘date’, ‘day’, ‘period’, and ‘class’: i. date: date range normalized between 0 and 1 ii. day: day of the week (1-7) iii. period: time in half hour intervals over 24 hours, normalized between 0 and 1 iv. class: binary classification
Output:
Instructions for output interpretation: • Output will be the instances at which drift has occurred and prediction results. • Output content type: A “.csv” file with the instances. • Supported content types: 'text/csv'.
Invoking endpoint:
