Eight reviews of the mechanism
Threshold: 7 out of 8. without a timer. Balls are given for answers, not for visits. This is a local self-check; the decisions will be shown after dispatch.
1. Column j of matrix A is equal to ...
Image e_j
Image of the whole plane
To the Gradient of each loss
2. In ABx, what conversion applies to x first?
A
B
They're always simultaneous.
3. The ring of the matrix is...
Number of non-zero cells
Column Space Size
Number of lines always
4. Is there a non-zero real eigenvector at 90° on the material plane?
Yeah, whatever.
None
Only [0.0]
5. det([[2,1],[0,1]])?
Your numerical response
6. Rang[1.2], [0.0]]?
Your numerical response
7. Frobenius error rank1 dice of diag(3.1)?
Your numerical response
8. How many scalars in the factors for m=n=4,r=1?
Your numerical response
The result will appear after all the answers have been sent.
Research and explain
Compare AB and BA on the two matrices of the lab. Then compare the rank1 SVD bend and diag(3.1): explain the role of equal sinular values and the lack of guarantee of utility for the task.
First, shape the hypothesis, then change one parameter. Compare the numbers to the formula; state the extreme case and the limit of applicability. The free conclusion is not evaluated by a dummy automatic score.
