Abstract: The disclosure herein describes providing action item information for a current activity based on similarity with past activities. Activity attributes indicative of an activity outcome are identified, and a random forest classifier based on the identified activity attributes is generated. The random forest classifier classifies an activity based on the activity attributes. Similarity factors associated with the current activity and past activities are calculated based on the random forest classifier. Based on the similarity factors, data value ranges of performance indicators of past activities associated with the activity outcome are determined. Based on comparing the determined data value ranges to performance indicator data values of the current activity, action item information associated with the performance indicator data values of the current activity is provided.
