Homepage of Hannes Nickisch

Hannes Nickisch After doing a PhD at the Max Planck Institute for Biological Cybernetics and a PostDoc at the Max Planck Institue for Intelligent Systems, I'm using machine learning and AI methods for medical image analysis tasks e.g. for cardiovascular1,2 and oncology applications as a Senior Scientist at Philips, Hamburg, Germany.

During my study times at the Technical University Berlin and the Université de Nantes I did internships with Microsoft Research in Cambridge, Siemens Corporate Research in Princeton and Siemens Medical Systems in Erlangen.

My research interests lie in probabilistic machine learning, computer vision and pattern recognition, medical image processing and predictive patient-specific biophysical models based on Gaussian processes and neural networks

Code and Data

gpml

GP The Gaussian Process for Machine Learning toolbox.

gpml A library for Gaussian process regression and classification for Octave/Matlab containing a variety of approximate inference schemes ranging from Laplace's method over expectation propagation to variational Bayes. We furthermore support large scale approximate inference via the FITC approximation and MCMC sampling.
See the mloss.org project (rank #19), the gitlab repository, the JMLR paper and the gpml page.


    cov = {@covSEiso}; sf = 1; ell = 0.4; hyp.cov = log([ell;sf]);
    lik = 'likLaplace'; sn = 0.2; hyp.lik = log(sn);
    mean = @meanZero;                   % set up GP (cov,lik,mean)
    nlZ = gp(hyp, 'infEP', mean, cov, lik, X, y);      % inference
    

AwA - Animals with Attributes

CV A dataset for Attribute-Based Classification.

AwA A dataset for benchmarking transfer-learning or zero-shot learning algorithms. The dataset contains 30475 images in 50 animal classes aligned with Osherson's well-known class/attribute matrix with 85 numerical attributes per class.
See the download website, the download website of the free successor dataset, the CVPR paper and the IEEE-TPAMI pdf.


OATH - Oslo Aurora THEMIS dateset

CV A dataset for aurora classification.

OATH A dataset containing manually labeled aurora images from the THEMIS all-sky imagers. The dataset contains a total of 5824 images in 6 different classes "arc", "diffuse", "discrete", "cloudy", "moon" and "clear". It can be used to train classifiers and benchmark algorithms.
See the download website and the NIRD archive for the images and a baseline and the related JGR paper.


glm-ie

ML The Generalised Linear Models Inference and Estimation Toolbox.

glm-ie A library for large scale matrix vector multiplication (MVM) based computations in generalised linear models for Octave/Matlab. We support variational Bayes, factorial mean field and expectation propagation as well as MAP estimation using a wide range of penalised least squares solvers for sparse estimation. A dedicated matrix class provides computational primitives and a wide range of regularisers are supported.
See the mloss.org project (rank #35), the JMLR paper and the glm-ie page.


    X = matConv2(f, su, 'circ');        % convolution matrix
    B = matFD2(su, 'circ');       % finite difference matrix
    pot = @potLaplace; s2 = 1e-4; tau = 15;
    [m,ga,b,z,nlZ] = dli(X,y,s2,B,pot,tau,opts); % inference
    pen = @(s) penAbs(s);                       % l1-penalty
    [u,phi]  = plsTN(u0,X,y,B,opt,s2,pen);      % estimation
    

gmm

GP Gaussian mixture modeling with Gaussian process latent variable models and others.

dgplvm The toolbox contains code for density estimation using mixtures of Gaussians. Starting from simple kernel density estimation using spherical and diagonal Gaussian kernels over manifold Parzen window until mixtures of penalised full Gaussians with only a few components, the toolbox covers many Gaussian mixture model parametrisation from the recent literature. Most prominently, the package contains code to use the Gaussian process latent variable model for density estimation.
See the mloss.org project and the corresponding DAGM paper or get the code here.


    [lp,lpte] = dkde(z,zte);      % diagonal kernel density estimation
    [lp,lpte] = mpar(z,zte,d,k);  % manifold Parzen windows
    [lp,lpte] = pgau(z,zte);      % penalised Gaussian
    

fwtn

The fast wavelet transformation for tensor data.

fwtn The code contains a standalone light-weight implementation of the orthonormal wavelet transform using quadrature mirror filters in C including a Matlab/MEX wrapper. We fully support D-dimensional data in L levels. The algorithm has a computational complexity linear in the size of the input.
See the mloss.org project or get the code here.


    qmf = [1,1]/sqrt(2); % Haar wavelet
    L   = 3;             % # levels in the pyramid
    W   = fwtn(X,L,qmf); % apply FWT, inverse: X = fwtn(W,L,qmf,1);
    

approxXX

GP A variety of approximate inference methods for Gaussian process prediction.

approxXX The code comprises expectation propagation, Laplace's method, the informative vector machine, Gaussian variational mean field, factorial mean field, on-line expectation propagation, TAP and variational bounding. Note that is numerically much less robust than the code in gpml. The implementations are meant to illustrate the algorithms as such and not for use as a black box system in an applied setting. The functions use the gpml v2.0 Octave/Matlab interface.
See the corresponding JMLR paper or get the code here.


    hyp = [1; 1];       % ell,sig - GP parameters
    cov = {'covSEiso'}; % covariance function
    lik = 'cumGauss';   % logistic or cumGauss likelihood
    apx = 'LA';         % EP,FV,IVM,KL,LA,LR,OLEP,SO,TAP,TAPnaive or VB
    p = binaryGP(hyp, ['approx',apx], cov, lik, x, y, xt); % prediction
