2 projects found that use cython as the programming language.
A collection of python code to perform research in optimization. The
aim is to provide reusable components that can be quickly applied to
machine learning problems.
- Ellipsoidal multiple instance learning
- difference of convex functions algorithms for sparse classfication
- Contextual bandits upper confidence bound algorithm (using GP)
- learning output kernels, that is kernels between the labels of a classifier.
HDDM is a python toolbox for hierarchical Bayesian parameter
estimation of the Drift Diffusion Model (via PyMC).
Drift Diffusion Models are used widely in psychology and cognitive
neuroscience to study decision making.
New and improved HDDM model with the following changes:
Priors: by default model will use informative priors
If you want uninformative priors, set
Sampling: This model uses slice sampling which leads to faster
convergence while being slower to generate an individual
sample. In our experiments, burnin of 20 is often good enough.
Inter-trial variablity parameters are only estimated at the
group level, not for individual subjects.
The old model has been renamed to
HDDMRegression and HDDMStimCoding are also using this model.
HDDMRegression takes patsy model specification strings. See
Improved online documentation at
A new HDDM demo at http://ski.clps.brown.edu/hddm_docs/demo.html
Ratcliff's quantile optimization method for single subjects and
groups using the
Maximum likelihood optimization.
Many bugfixes and better test coverage.
hddm_fit.py command line utility is depracated.
