SciPy - Advanced Optimization
Which argument in
scipy.optimize.least_squares specifies the function that computes residuals?Which argument in scipy.optimize.least_squares specifies the function that computes residuals?
easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Identify the role of each argument
funis the function that returns residuals;jacis the Jacobian;x0is the initial guess;boundsrestricts parameter values.Step 2: Confirm which argument computes residuals
The residual function is passed asfuntoleast_squares.Final Answer:
fun -> Option CQuick Check:
Residual function argument = fun = B [OK]
Quick Trick: Residual function is always passed as 'fun' in least_squares [OK]
Common Mistakes:
- Confusing 'jac' with residual function
- Using 'x0' as function argument
- Mistaking 'bounds' for residual function
