Solution Overview

Problem

Existing AI models can be compromised by poisoned training data, leading to untrustworthy inferences and the need for computationally expensive re-training, which disrupts inference consumption and other services.

Innovation Solution

Analyze candidate training data sets by comparing causal relationships with historical data to identify potential poisoning, using a threshold to determine if the data is poisoned, thereby reducing the need for re-training and conserving computational resources.

Solution Approach 1:

The patent applies preliminary action by detecting poisoned training data before re-training the AI model. The system analyzes training data sets to identify poisoned samples in advance, allowing the model to be re-trained only when necessary and using cleaned data, thus avoiding unnecessary re-training time while maintaining model reliability

Inventive Principle:

AI summary

Methods and systems for managing artificial intelligence (AI) models are disclosed. To manage AI models, an instance of an AI model may not be re-trained using training data determined to be potentially poisoned. By doing so, malicious attacks intending to influence the AI model using poisoned training data may be prevented. To do so, a first level of strength of a first causal relationship present in historical training data may be compared to a second level of strength of a second causal relationship present in a candidate training data set. The first level of strength and the second level of strength may be expected to be similar within a threshold. If a difference between the first level of strength and the second level of strength is not within the threshold, the candidate training data may be treated as including poisoned training data.
