Chapter 7 typo

[rickiepark]

(p225) In the middle of page,
"argmax_i [0.2 \times i_0 + 0.2 \times i_0 + 0.6 \times i_1]" should be "argmax_i [0.2 \times i_0 + 0.2 \times i_0, 0.6 \times i_1]"

Sorry I misunderstood it.
"argmax_i [0.2 \times i_0 + 0.2 \times i_0 + 0.6 \times i_1]" is right. :)

(p234) In 3rd line of the first code block, print("Accuracy: ...") should be print("ROC AUC: ..."), because output text is ROC AUC: ....

[rickiepark]

(p237) In 3rd line, "inside a GridSearch object" should be "inside a GridSearchCV object".

[rickiepark]

(p221) In 2nd eq. in the page,
"1 if \sum_{i} C_{j}(x) \ge 0" should be "1 if \sum_{j} C_{j}(x) \ge 0"

[rickiepark]

(p248) In step 3, \hat{y} eq. is ambiguous. I suggest \hat{y} = sign[\sum_{j=1}^{m} (\alpha_j \times predict(C_j, X))].

(p250) End of the 1st paragraph, "(step 4)" should be "(step 3)".

Oh yes, definitely. Thanks!

(p237) In 3rd line, "inside a GridSearch object" should be "inside a GridSearchCV object".

Yes!

(p221) In 2nd eq. in the page,
"1 if \sum_{i} C_{j}(x) \ge 0" should be "1 if \sum_{j} C_{j}(x) \ge 0"

Thanks!

Yes, that's better

(p250) End of the 1st paragraph, "(step 4)" should be "(step 3)".

Yes
