clmtrackr
Javascript library for precise tracking of facial features
clmtrackr is a javascript library for fitting facial models to faces in videos or images. It currently is an implementation of constrained local models fitted by regularized landmark mean-shift, as described in Jason M. Saragih's paper. clmtrackr tracks a face and outputs the coordinate positions of the face model as an array. The library provides some generic face models that were trained on the MUCT database and some additional self-annotated images. -

INFOS
NMR spectrum fitting software
NOW COMPILED FOR USERS WITHOUT A MATLAB LICENSE! Download INFOS_comp_***.zip. INFOS is a set of programs for fitting NMR spectra in MATLAB. INFOS improves on existing methods by calculating peak shapes using acquisition and processing parameters, therefore leading to better fits. Additionally, INFOS can determine the peak list for fitting, by using iterative refinement of the list in order to improve the fit without overfitting. INFOS also can be used to analyze error of fit parameters, can fit series of NMR spectra to user-defined functions, and can be used interactively for 2D spectra. ... -

BasisFit
Quantum chemistry utility program
BasisFit extracts molecular orbitals from a GAMESS data file and constructs near-identical orbitals from an alternative basis set using least-squares fitting of the new basis functions to the old. This is particularly useful for generating physically sensible starting orbitals for CASSCF calculations from atomic minimal basis Hartree-Fock orbitals, but can be used to convert any converged set of orbitals from one basis to another. -

Kinetic Model Builder
GUI for building, simulating and optimizing kinetic models.
...Models can be represented as either states and connecting transitions or interacting allosteric elements (see http://dx.doi.org/10.1085/jgp.201411183). Model parameters can be optimized by fitting model responses to user data. Optional user defined constraint equations for model parameters are parsed with EigenLab (https://github.com/marcel-goldschen-ohm/EigenLab). Convenient simulation and summarization across 2-dimensional sets of stimulus conditions makes constructing stimulus-response curves incredibly simple. For ion channels, this is useful for simulating dose-response or current-voltage curves both with and without a secondary stimulus (e.g. some drug). ... -

CurvatureFilter
Curvature Filters are efficient solvers for Variational Models
...Traditional solvers, such as gradient descent or Euler Lagrange Euqation, start at the total energy and use diffusion scheme to carry out the minimization. When the initial condition is the original image, the data fitting energy always increases while the regularization energy always reduces during the optimization. Thus, regularization energy must be the dominant part since the total energy has to decrease. Therefore, Curvature filters focus on minimizing the regularization term, whose minimizers are already known. For example, if the regularization is Gaussian curvature, the developable surfaces minimize this energy. -

BPL
Bayesian Program Learning model for one-shot learning
...The approach treats each concept (e.g. a character) as being generated by a probabilistic program (motor primitives, strokes, spatial relationships), and inference proceeds by fitting those generative programs to a single example, generalizing to new examples, and generating new exemplars. The repository contains code for parsing stroke sequences, fitting motor programs, exemplar generation, classification, re-fitting, and demonstration scripts. -

EDM Calibration Baseline Fitting
EDMFit is an adjustment tool to estimate EDM calibration parameters.
An EDM calibration baseline is used to derive specific instrument errors of the electronic distance measurement (EDM) unit of a total station. EDMFit is a simple adjustment tool to estimate the EDM calibration parameters (addition constant and/or scale parameter). The adjustment process is according to ISO 17123-4. The parameters are checked for significance, to avoid an overestimation. Based on two classical hypothesis testing, EDMFit provides a reliable outlier detection. For... -

fitGCP
Fitting genome coverage distributions with mixture models
...Thus, biases such as fragmented or erroneous reference genomes often remain unaccounted for. Making this information accessible can improve the quality of sequencing experiments and quantitative analyses. fitGCP is a framework for fitting mixtures of probability distributions to genome coverage profiles. Besides commonly used distributions, fitGCP uses distributions tailored to account for common artifacts. The mixture models are iteratively fitted based on the Expectation-Maximization algorithm. Please find the accompanying paper here: http://dx.doi.org/10.1093/bioinformatics/btt147 -
