I'm trying FullBatchLBFGS with wolfe line search on a fitting task of a small dataset.
1. Levenbert-Marquardt is giving me fairly accuracy. Can I expect LBFGS provide similar accuracy as LM? Say,…

Given A approximately equal to XY where A is the original matrix (say customers as rows and attributes of customers as columns).
If the GRLM function is used for dimensionality reduction and the rows…

Consider the following SOCP (per @wkschwartz)
```
import cvxpy as cv
u = cv.Variable(2)
constr = [u[1] - u[0] = 0]
prob1 = cv.Problem(cv.Minimize(cv.norm(u)), constr)
```
Clearly, we could equ…

_statsmodels.mixedlm_ generates different results under Python 2.7 and Python 3.4. Moreover, in Python 3.4, the model does not converge when _re_formula_ is used with variable slope.
Here is a simp…

Hello,
1. What package do you use to read RSSI measurements?
2. Where are the locations of WIFI APs (used in path loss model) and trained Gaussian Processes model stored?
3. How can I map and train…

I'm making a game where obstacles can be placed during run time. Right now I've added a very simple grid generator that saves tile removals and regenerates the NavMesh from a new array, but it definit…
