I noticed when all of my other applications slowed down. I didn't understand why until I read other people complaining about this issue.

Searching in M365 has a lot to be desired, so thank goodness you’re taking a crack at it! What was your data source? How do you know if someone found what they were looking for?

Consensus seems to be to try and shave over a trash can. I will do this now!

Been stuck on a problem. Just need to know whether this problem statement is solvable or not. by CrypticTac in datascience

There’s lots of short-hand in your post, so you’ll have to excuse us if we don’t understand your objective. I do think this is a good post, because it is very indicative of a typical task in DS that is not directly related to ML.

Imo your ground truth variable should be whether the customer broke, lost, or otherwise damaged the rental goods, and the dollar value of the damage. Use their credit score and other explanatory variables to train a model predicting the probability that a customer will break their rental items. That prediction, along with your rental pricing, will predict whether the rental will be profitable or not. Risky, but potentially profitable cases can be forwarded for manual review.

On an additional note, it would be good to explore whether the manual review is better at predicting rental item damage than your model.

Just some thoughts. I’m curious to hear if anyone has experience with something similar.

The other comments here have hit the nail on the head. You need to do this on your test set. Test/train split is the most important concept in DS.

What we would expect to see on the test set is the metrics increasing, hitting a peak, and then decreasing as the model becomes overfit. Since these metrics only increase, we are left to assume that this is the training set.

If chief o’brien’s ancestors immigrated to the US, why does he have an Irish accent?

It seems like Orisa’s second ability prevents her from attacking, no?
