Abstract: According to an aspect of an embodiment, a method may include obtaining first interactions with a website associated with a first product listed for sale on the website. The method may also include grouping, into a first data set and a second data set, the first interactions according to when the first product enters a second state of a multi-state progression of being sold. The method may also include training a machine-learning model using the first data set and the second data set. The method may also include obtaining second interactions associated with a second product. The method may also include obtaining a confidence of an expected state of the second product in the multi-state progression by using the second interactions with the machine-learning model. The method may also include predicting a likelihood that the second product enters the expected state within a particular period of time.
