Abstract: Classification of cell data includes obtaining a target dataset and an artificial intelligence (AI) model trained to identify relationship(s) between cells of a row and classify whether a focus cell of the row is erroneous based on the identified relationship(s), and applying the AI model to the target dataset to identify erroneous cell(s) thereof. The applying includes selecting a row of cells of the target dataset, inputting the selected row of cells to the AI model with an identification of a focus cell, the focus cell to be classified by the AI model, classifying the focus cell to obtain a classification of the focus cell, the classifying identifying whether the focus cell is erroneous, and outputting an indication of the classification of the focus cell.
