GUIDED WORKFLOW FOR DEEP LEARNING ERROR ANALYSIS
A model management system performs error analysis on results predicted by a machine learning model. The model management system identifies an incorrectly classified image outputted from a machine learning model and identifies using the Neural Template Matching (NTM) algorithm, an additional image correlated to the selected image. The system outputs correlated images based on a given image and a selection by a user through a user interface of a region of interest (ROI) of the given image. The region is defined by a bounding polygon input and the correlated images include features correlated to the features within the ROI. The system prompts a task associated with the additional image. The system receives a response that includes an indication that the additional image is incorrectly labeled and including a replacement label and instruct that the machine learning model be retrained using an updated training dataset that includes the replacement label.
1 . A method comprising:
identifying an incorrectly classified image outputted from a machine learning model;
receiving, through a user interface, an input of a replacement label for the incorrectly classified image from the user;
prompting the user, through the user interface to select an error type for further investigation from a presented group of error types, wherein the group of error types to present is selected based on a ranking of loss associated with each error type, the error type associated with a category of incorrectly classified images; and
instructing that the machine learning model be retrained using an updated training dataset that includes the replacement label.

instructing that the machine learning model be retrained with the training dataset.
5 . The method of claim 1 , further comprising:
determining a score, for each incorrectly classified image in a group of incorrectly classified images of a same category; and
determining a ranking of the incorrectly classified images in the group based on the score.
6 . The method of claim 5 , wherein the score is determined based on a loss function used in the machine learning model.
7 . The method of claim 1 , further comprising:
responsive to detecting a selection of the error type, prompting, through the user interface, a plurality of additional tasks associated with the category of incorrectly classified images, each additional task being a concrete action for a user to perform for fixing the error type.
8 . The method of claim 7 , wherein the plurality of additional tasks includes one or more of: presenting an image for the user to examine, presenting images to the user for relabeling, presenting a plurality of images for the user to choose from, or presenting two or more images for the user to compare.
9 . The method of claim 7 , further comprising:
determining a root cause based on responses received to the plurality of additional tasks for the type of error; and
providing, through the user interface, an action that addresses the root cause of the type or error.
10 . The method of claim 9 , wherein the action is one or more of: fixing image labels, updating a labeling convention, adding additional data for training, changing model hyperparameters, modifying data augmentation.
