Multi-task image classifier for classifying inherently ordered values

In an approach for classifying an image containing a continuous characteristic using an image classifier, an image tagged with a single value is received, wherein the single value is from a set of ordered value. A processor sets at least two thresholds based on the set of ordered values. A processor derives at least two labels according to the single value tagged in the image and the at least two thresholds. A processor runs image through an image classifier. A processor receives at least two predictions from the image classifier based on the at least two labels. A processor adjusts the image classifier based on differences between the at least two predictions and the at least two labels.
