Publication number: 20260099763Abstract: Mechanisms are provided for performing an artificial intelligence (AI) model explainer for an AI computer model. The mechanisms receive input data comprising non-numeric feature data, which may be results generated by the AI computer model. The mechanisms process the non-numeric feature data via a first computer model trained to convert non-numeric feature data into a numeric representation of the non-numeric feature data. The mechanisms input the numeric representation of the non-numeric feature data into the AI model explainer to generate an AI model explanation output having a portion corresponding to the numeric representation of the non-numeric feature data. The mechanisms process the AI model explanation output via a second computer model that is trained to convert the portion from the numeric representation to an output non-numeric representation consistent with the non-numeric feature data and the converted output may then be output.Type: ApplicationFiled: October 8, 2024Publication date: April 9, 2026Inventors: Meng Wan, Xiang Yu Xue, Sheng Yan Sun, Mai Zeng
