Natural language processing is becoming one of the most widely adopted machine learning technologies in the enterprise, used in everything from customer support chatbots to automated document processing systems. But organisations often struggle to find the right tools to monitor these models—until now. Arthur, the machine learning model monitoring company, is releasing a suite of new tools and features for monitoring natural language processing models.
The Arthur platform now offers advanced performance monitoring for NLP models, including tracking data drift—one of the most pernicious issues when it comes to maintaining model performance—bias detection, and prediction-level model explainability. Monitoring NLP models for data drift involves comparing the statistical similarity of new input documents to the documents used to train the model. The Arthur platform monitors NLP models for data drift and automatically alerts you when your input documents or output text starts drifting beyond pre-configured thresholds.
Arthur now also offers bias detection capabilities for NLP models, allowing data science teams to uncover differences in accuracy and other performance measures across different subgroups to identify—and fix—unfair model bias. The Arthur platform offers performance-bias analysis for natural language and tabular models, as well as the ability to partition by multiple attributes at a time to provide you more granular insights into potential biases.
The Arthur team has also released a new set of explainability tools for NLP models, providing token-level insights for language models. Organisations can now understand which specific words within a document contributed most to a given prediction, even for black-box models.
Arthur’s customers, including Fortune 100 companies like Humana and AI-driven startups like Expel and Truebill, are using the platform to ensure that they can catch and fix any issues with their production AI systems before they become billion-dollar problems. With Arthur’s new NLP monitoring capabilities, the platform can now offer advanced support for an entirely new class of models that are rapidly becoming fixtures in the enterprise.
