Solution Overview

Problem

Conventional digital assistant platforms lack visibility into the performance of deployed models, failing to provide insights when the digital assistant performs poorly or degrades over time, and do not monitor data characteristics such as bias, drift, and outliers.

Innovation Solution

A performance controller with microservices for model explainability and data characteristic detection is integrated into the digital assistant platform, providing model interpretability and monitoring data bias, data drift, and outliers through explanation models and ensembling techniques.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If conventional digital assistant platforms are used, then the digital assistant can perform natural language processing tasks, but the platform lacks visibility into model performance and cannot detect data characteristics such as bias, drift, and outliers

Engineering Contradiction:
Improvemodel performance visibilityVSAvoidplatform architecture
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent introduces a performance controller as an intermediary component that sits between the machine learning model and the production environment. This controller includes explanation models and data characteristic detection capabilities that monitor and analyze model performance without requiring fundamental changes to the existing digital assistant platform architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements self-monitoring capabilities where the performance controller automatically generates performance metrics, detects data characteristics, and provides explanations for model behavior. This allows the platform to monitor its own performance without requiring external manual analysis, thereby maintaining operational simplicity while gaining performance visibility.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If multiple explanation models are applied to generate performance metrics, then model interpretability is improved, but the processing time and computational resources increase

Engineering Contradiction:
Improvemodel interpretabilityVSAvoidperformance metric generation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent combines multiple explanation models into a unified performance controller that processes model outputs simultaneously. By merging the functionality of different explanation models (such as LIME, SHAP, and counterfactual explanations) into a single integrated system, the patent achieves comprehensive model interpretability while optimizing resource utilization and reducing redundant computations.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If continuous performance monitoring is implemented, then the effectiveness of the digital assistant is maintained, but the system complexity and computational overhead increase

Engineering Contradiction:
Improvedigital assistant effectivenessVSAvoidsystem architecture
Core Design Contradiction:

Solution Approach 1:

The performance controller implements continuous feedback loops that monitor model performance metrics and data characteristics in real-time. The system generates performance metrics from production data and feeds this information back to stakeholders, enabling continuous verification of model effectiveness without requiring complex manual intervention systems.

Inventive Principle:
Principle #23Feedback

AI summary

A method may include training, based at least on a first data, a machine learning model to perform one or more natural language processing tasks. The trained machine learning model may be deployed to a production environment to support natural language based interactions with a digital assistant. A plurality of performance metrics may be generated to include explanation data associated with the deployed machine learning model operating on a second data as well as one or more data characteristics of the second data such as data drift, data bias, and outliers. A user interface may be generated to display, at a client device, a visual representation of at least a portion of the plurality of performance metrics associated with the deployed machine learning model.
