Проверив работу у меня получилась оценка в 95 балов. Но потом я глянул бал в Score таблице и там оказался 0 (ноль). Видется мне, что товарищ не проверял чужие работы. За что и получил свой 0. В изменении оценки смысла не вижу.
Средний бал вместе с моей из выставленных составляет (98 + 130 + 95 + 118) / 4 = 110.25 Такую оценку он мог бы получить.
score: 8
Task 5 (up to 5 points)
Extract float number from Value field in DataFrame (0.5 points) BAD 60K => 60 000 000 неверная конвертация тысяч. (60K == 60 000) || 0
Сhoose more features that you expect to influence on player Value (at least 10) Plot feature correlation matrix. (0.5 points) OK || 0.5
_Drop features that are highly correlated with each other (abs(corr) > 0.9) one by one until no correlated pairs left. Hint: you may reuse code from Task_9 in HW1 for automatic correlated pairs selection. (1.5 points) Penalties: -0.5 points if did not remove linearly dependent features before training the model. || -0.5
Split data into train/test with some proportion (0.5 points) OK || 0.5
Train a model on train dataset, make predictions both for train and test. (0.5 points) OK || 0.5
Measure the model quality in terms of MSE in train and test samples, (0.5 points) OK || 0.5
Write a short report about the work done. Why did you take these particular features? Can you find a logical explanation for high correlation of some of your features? Are you satisfied with the quality of predictions? etc. (1 point) NOT OK Report is out. || 0
I was a bit lost with the rule I did not know that we have a specific time apart from the date, however I have check all other work on the same date. Maybe you will give a mark for this time, as a lesson learned. Now I am checking other tasks before the specific time. @JackNightsky Please.
I would put 0. After consulting with other activists, given that this is the first homework assignment, we decided to put the mark on which I checked the work - 95. I hope now you check the work on the very first day after they appear for review. @Kaktuscha
Also, your post-deadline review of other work did not affect the other students' scores. Because grades given after the deadline are not counted. So you framed these students.
@JackNightsky Thank you, I will check the remaining cross-checks on time.
Issue is verified and score is updated
