Criar modelos de ML com o BigQuery ML: laboratório com desafio avaliações

Very disappointing. 1) The dataset is not clearly specified, the features neither (is the goal to check per unique visitor or per session?) 2) in the assignment, two contradicting instructions are given: "Also you have to specify the model type as binary logistic regression" and 2 lines below "Use the model type as linear regression model" - the second doesn't make sense for binary classification (will or won't buy). 3) No specification on how to deal with train-validation split; some labs have the split, some don't, it's ambiguous 4) even after trying all combinations (even with the linear regression, i.e. fitting the number of transactions as if it were float) the result gets NOT verified by the module. I got the data and trained a model myself separated from GCP and got THE SAME results as here, so obviously the model is well trained. Sad work out there, sorry.

It is important to make the instruction clearer stating that the student is to use already trained models and not to train another subscriber_type model. It can be confusing

ラボの成功判定が問題文だけでは再現できないレベルに複雑すぎて、チャットサポートなしではクリア不可能

The instruction in the last task is not clear, so it is impossible to understand what is being returned wrongly.
