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. Parents ask the node...
Operation Dependence
Order of words in reply
Ready Gradient
2. Does the correct forward prove the backward correct?
Yes
None
Only for large graphs
3. For c=a*b the derivative is a equals...
a
b
1
4. The initial derivative dL/dL is equal to...
0
1
Value L
5. L=(xw+b)2 at x2,w3,b1?

8. d(u+u)/dx at u=x2,x2?
Your numerical response
The result will appear after all the answers have been sent.
Research and explain
Gather the JSON DAG with a common node and repertoire operands. Go through the steps and reverse the steps, explain the contributions before/after each node. Check one gradient central difference and name the reLU limit in 0.
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.
