SciPy - Advanced Optimization
What parameter does a callback function receive when used with
scipy.optimize.minimize?What parameter does a callback function receive when used with scipy.optimize.minimize?
easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Check callback signature
Inscipy.optimize.minimize, the callback receives the current parameter vector.Step 2: Parameter type
This vector is typically a NumPy array or list representing current variables.Final Answer:
The current parameter vector as a NumPy array or list -> Option CQuick Check:
Callback does not receive function value or iteration count directly. [OK]
Quick Trick: Callback gets current parameters vector only [OK]
Common Mistakes:
- Expecting callback to receive function value
- Assuming iteration count is passed to callback
- Thinking callback receives full optimization result
