Confusion Matrix for Feedback: Suppose that for the following three-class confusion matrix we have a very accurate binary classifier for distinguishing classes B and C. Find the four elements in the reduced confusion matrix (lower).
![The image contains a matrix and an exercise related to it. The matrix is composed of three rows labeled "From A," "From B," and "From C," and three columns also labeled "A," "B," and "C." The matrix entries are as follows:
- Row "From A": 0.86, 0.06, 0.08
- Row "From B": 0.12, 0.55, 0.33
- Row "From C": 0.13, 0.29, 0.58
Below the matrix, there's an exercise prompt:
"Fill in:
From \[
\begin{bmatrix}
A \\
B + C
\end{bmatrix}
\right]
\begin{bmatrix}
\ \, \, \\
\ \, \,
\end{bmatrix}
\]"
This suggests that students need to fill in the indicated section with numbers or expressions, likely derived from interpreting or calculating with the given matrix.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F83102d4e-2b77-4deb-80f2-5435307f6c89%2F90548ac5-1acd-4171-af5b-093920f909a1%2Fre9vrb_processed.jpeg&w=3840&q=75)
