Efficient machine learning training on spreadsheet data

A method comprising:

• displaying an interactive spreadsheet on a display of a user device, wherein the interactive spreadsheet displays values in cells arranged by row and column;
• receiving an input from the user that identifies cells with existing values in the spreadsheet to be validated;
• in response to the input:
• dividing the cells into two or more subsets comprising input features and corresponding target outputs to the cells to be validated;
• for each subset, training a machine learning model on the values in the cells in the other subsets to predict values for the cells to be validated;
• for each subset, generating a predicted value for each cell to be validated using the machine learning model that was trained for the subset;
• and
• displaying an indication of which cells to be validated have existing values which are likely to be abnormal on the user device.

A system comprising one or more computers and one or more storage devices storing instructions that when executed by the one or more computers cause the one or more computers to perform operations comprising:

• displaying an interactive spreadsheet on a display of a user device, wherein the interactive spreadsheet displays values in cells arranged by row and column;
• receiving an input from a user that identifies one or more cells to be filled in with respective predicted values;
• in response to receiving the input:
• training a machine learning model on the values in the cells of the interactive spreadsheet to predict respective values for the one or more identified cells;
• generating a respective predicted value for each of the identified cells using the trained machine learning model;
• and
• displaying the respective predicted values on the user device.

One or more non-transitory computer-readable storage media storing instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

• displaying an interactive spreadsheet on a display of a user device, wherein the interactive spreadsheet displays values in cells arranged by row and column;
• receiving an input from a user that identifies one or more cells to be filled in with respective predicted values;
• in response to receiving the input:
• training a machine learning model on the values in the cells of the interactive spreadsheet to predict respective values for the one or more identified cells;
• generating a respective predicted value for each of the identified cells using the trained machine learning model;
• and
• displaying the respective predicted values on the user device.
