QUESTION
I am trying to add tf.data pipeline to a regression task. The code starts with reading in the continues values using the csv file and inputting the images with cv2.imread. I split the data to train, test and validation using sklearn preprocessing.

QUESTION
I have to write an algorithm in C and Python to know if a point belongs to a polygon or not (all entered by the user). My algorithm works in python but the C one doesn't work and I can't find my errors since my debugger code blocks refuse to work. So if someone could tell me where my error is, I would be very grateful...
The user is asked for the number of vertices of the polygon n≥3 (while). We ask for their coordinates (For) which we store in 2 arrays (CoordX/CoordY). The coordinates of the point to be tested are requested (TestX/TestY). We find the equations of lines connecting the points that follow each other (For). General case: we look for a and b of y = ax + b. a= (y(i+1) - y(i))/(x(i+1) -x(i)); b=y-ax
Special case: if the point at x, (i+1) - i = 0 then we have a line of equation y = x = k (constant) with b = 0; Line = True. if the point at y, (i+1) - i = 0 then we have a line with equation y = b with a = 0.
We determine if the point is between the bounds y(i) and y(i+1) (For) in order to know which line will cross the point to be tested: Bound = True/False, which we store in an array of Booleans, TabBorne.
We count the number of lines that the point to be tested will cross if we tend x towards infinity (For); we increment k (we take care to use only the lines that we will cross (If)).
y=ax+b<=>x= (y-b)/a,a≠0
Special case: if a point lies on a vertex, Vertex = True and the point lies in the figure.
We count the number of lines touched % 2 : If = 1, it is inside the polygon; Otherwise, it is outside.

QUESTION
I would like to use the AUC for the Precision and Recall curve as a metric to train my model. Do I need to make a specific scorer for this when using cross validation?
Consider the below reproducible example. Note the imbalanced target variable.
...ANSWER
Answered 2021-May-25 at 02:10"Average precision" is what you probably want, measuring a non-interpolated area under the PR curve. See the last few paragraphs of this example and this section of the User Guide.
For the scorer, use "average_precision"
; the metric function is average_precision_score
.

and I got results metrics:
ANSWER
Answered 2021-May-09 at 22:16When you apply one-hot-encoding for binary classification these metrics mess up. Here is an example:
Your labels looks like this after one hot encoding: [ ... [1,0], [0,1], [1,0] ... ]
If you pay attention your TP
equals TN
. When it is correctly predicted as class 0, it is TP
for class 0, also TN
for class 1. That's why they are equal.
Don't apply one hot encoding and change:

I'm trying to limit the time subscriptions are cached in rxjs. Previously the caching was done with pipe(publishReplay(1), refCount())
. After finding this nice answer and reading the docs, I found out that this cache time can be limited by passing a second parameter to publishReplay
.
Example: publishReplay(1, 60 * 1000)
