I think your question might deserve more credit than the response by @dkaila. If everyone "makes that bit up" - trivial or otherwise, how are they going to declare a winner? I'm assuming they will in some way validate the results on the test set?

Different people are bound to make different adjustments to the data in order to purify it. Without a target your whole data to information pipeline is backward should you validate the answer assuming a target (because your target is in this case a function of the data?).

Now I haven't attempted this challenge myself, but it seems to me if 5 people calculated the response differently they could all backpropogate high accuracies but recieve ambigious scores on your test results - all due to the response itself being "trivial"?

Now I understand this should be trivial. Just remarking on the fact that the answer to this question may not be so simple as to provoke a retort -> ` If you cant make that bit up........ 🤷🏿‍♂️ `.

The Data doesnt explicitly have a target value,you create it. Use the groupby function of the ride_id column and aggegate by count,you will get the number of tickets that were sold per id. or just follow the notebook that was shared by one of us https://github.com/pawelmorawiecki/traffic_jam_Nairobi/blob/master/RandomForest.ipynb
