confusion matrix
how does the histogram2d functions here?
Hey Niranjan,
Thank you for reaching out!
The histogram2d function works as follows. Imagine a 2D coordinate system. The first parameter (actual_values) is plotted along the y-axis, while the second parameter (pred_values) is plotted along the x-axis. Then, imagine that tick marks are placed at 0.0, 0.5, and 1.0 on each of the axes. These tick marks mark the edges of the two bins, namely
- a bin between the values 0.0 and 0.5
- a bin between the values 0.5 and 1.0
This splits the screen into four sectors. Just as in a conventional 1-dimensional histogram, in this 2-dimensional version we count the number of occurances in each sector. The resulting histogram has become our confusion matrix.
For further information, please refer to the function's official documentation:
