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. In z = wTx+b the displacement b...
Depends on each entrance as an activation
Added to sum independently of x
Is a gradient
2. At w=0 the normal separation of hyperplane...
Always vertical.
Emerging: score is constant
It matches sigmoid.
3. When soaking the sigmoid local derivative...
Approaching 0
Always equals 1.
Changes the size of the entrance
4. In the laboratory of GELU...
Computed exact Gaussian CDF
Uses a signed tanh-approximation
It matches ReLU.
5. z at x=[1.2],w=[1 - 1],b=5?
Your numerical response
6. σ(0)?
Your numerical response
7. σ′(0)?
Your numerical response
8. The exit of the structural XOR at [1.1]?
Your numerical response
The result will appear after all the answers have been sent.
Research and explain
Change separately x,weights,b and action. Show that the same class does not mean equal probability. Disable ReLU constructive XOR and compute all four answers.
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.
