Machine Learning (ML) model monitoring is an important step in the deployment and management of machine learning models. ML monitoring tools allow data scientists to monitor the performance of their models in production. ML model monitoring tools help organizations:

Track the accuracy and performance of the models in a production environment.
Detect input data issues and report any anomalies.
Gather data about model accuracy and data issues, and store captured data for visualization and analysis.

To be categorized as a ML model monitoring tool, a product must provide:

Detect and troubleshoot ML issues Should integrate with existing ML workflow.
Track model performance in real-time.
Send timely alerts and notifications for any performance degradation.

How relevant, verifiable metrics drive AIMultiple’s rankings

AIMultiple uses relevant & verifiable metrics to evaluate vendors.

Metrics are selected based on typical enterprise procurement processes ensuring that market leaders, fast-growing challengers, feature-complete solutions and cost-effective solutions are ranked highly so they can be shortlisted.
Data regarding these metrics are collected from public sources as outlined in the “What are AIMultiple’s data sources?” section of this page.

There are 2 ways in which vendor metrics are processed to help prioritization:
1- Vendors are grouped within 4 metrics (customer satisfaction, market presence, growth and features) according to their performance in that metric.
2- Vendors that perform high in these metrics are ranked higher in the list.

The data used in each vendor’s ranking can be accessed by expanding the vendor’s row in the below list.
This page includes links to AIMultiple’s sponsors. Sponsored links are included in “Visit Website” buttons and ranked at the top of the list when results are sorted by “Sponsored”. Sponsors have no say over the ranking which is based on market data. Organic ranking can be seen by sorting by “AIMultiple” or other sorting approaches.
