One step of gradient descent · Part 3 of 4
A logistic model predicts , where , with one weight and no bias. It starts at and trains on a single example with and label , using the cross-entropy loss .
You take one gradient-descent step with learning rate 0.5. What is the new loss, to three decimal places?
Answer with a number. Fractions, powers and expressions like 23/6 or C(52,5) are read correctly in practice.
