14. Discrete vs Continuous

Discrete vs Continuous Predictions

In the last few videos, we learned that continuous error functions are better than discrete error functions, when it comes to optimizing. For this, we need to switch from discrete to continuous predictions. The next two videos will guide us for doing that.

12 Discrete

Discrete vs. Continuous

The sigmoid function is defined as sigmoid(x) = 1/(1+e-x), If the score is defined by 4x1 + 5x2 - 9 = score, then which of the following points has exactly a 50% probability of being blue or red?

SOLUTION:
  • (1, 1)
  • (-4, 5)
