Logo KeLP 2.0.1

by kelpadmin - January 13, 2016, 12:47:31 CET [ Project Homepage BibTeX BibTeX for corresponding Paper Download ] 5745 views, 1430 downloads, 3 subscriptions

About: Kernel-based Learning Platform (KeLP) is Java framework that supports the implementation of kernel-based learning algorithms, as well as an agile definition of kernel functions over generic data representation, e.g. vectorial data or discrete structures. The framework has been designed to decouple kernel functions and learning algorithms, through the definition of specific interfaces. Once a new kernel function has been implemented, it can be automatically adopted in all the available kernel-machine algorithms. KeLP includes different Online and Batch Learning algorithms for Classification, Regression and Clustering, as well as several Kernel functions, ranging from vector-based to structural kernels. It allows to build complex kernel machine based systems, leveraging on JSON/XML interfaces to instantiate prediction models without writing a single line of code.

Changes:

In addition to minor bug fixes, this release includes:

  • Soft Confidence Weighted Classification algorithm: a brand new online learning algorithm from Wang, J., Zhao, P., Hoi, S.C.: Exact soft confidence-weighted learning. In Proceedings of the ICML 2012. ACM, New York, NY, USA (2012)

  • Optimization of the kernel caching mechanism

  • The Smooth Partial Tree Kernel and the Partial Tree Kernel now have the possibility to specify a maximum branching factor (parameter: maxSubseqLeng) in the tree fragments considered by the kernel operation.

Check out this new version from our repositories. API Javadoc is already available. Your suggestions will be very precious for us, so download and try KeLP 2.0.1!

(based on 1 vote)

About: A scalable, fast C++ machine learning library, with emphasis on usability.

Changes:
  • Removed overclustering support from k-means because it is not well-tested, may be buggy, and is (I think) unused. If this was support you were using, open a bug or get in touch with us; it would not be hard for us to reimplement it.
  • Refactored KMeans to allow different types of Lloyd iterations.
  • Added implementations of k-means: Elkan's algorithm, Hamerly's algorithm, Pelleg-Moore's algorithm, and the DTNN (dual-tree nearest neighbor) algorithm.
  • Significant acceleration of LRSDP via the use of accu(a % b) instead of trace(a * b).
  • Added MatrixCompletion class (matrix_completion), which performs nuclear norm minimization to fill unknown values of an input matrix.
  • No more dependence on Boost.Random; now we use C++11 STL random support.
  • Add softmax regression, contributed by Siddharth Agrawal and QiaoAn Chen.
  • Changed NeighborSearch, RangeSearch, FastMKS, LSH, and RASearch API; these classes now take the query sets in the Search() method, instead of in the constructor.
  • Use OpenMP, if available. For now OpenMP support is only available in the DET training code.
  • Add support for predicting new test point values to LARS and the command-line 'lars' program.
  • Add serialization support for Perceptron and LogisticRegression.
  • Refactor SoftmaxRegression to predict into an arma::Row object, and add a softmax_regression program.
  • Refactor LSH to allow loading and saving of models.
  • ToString() is removed entirely (#487).
  • Add --input_model_file and --output_model_file options to appropriate machine learning algorithms.
  • Rename all executables to start with an "mlpack" prefix (#229).

Logo ELKI 0.7.0

by erich - November 27, 2015, 18:23:16 CET [ Project Homepage BibTeX BibTeX for corresponding Paper Download ] 17418 views, 3192 downloads, 4 subscriptions

About: ELKI is a framework for implementing data-mining algorithms with support for index structures, that includes a wide variety of clustering and outlier detection methods.

Changes:

Additions and Improvements from ELKI 0.6.0:

ELKI is now available on Maven: https://search.maven.org/#artifactdetails|de.lmu.ifi.dbs.elki|elki|0.7.0|jar

Uncertain data types, and clustering algorithms for uncertain data.

Major refactoring of distances - removal of Distance values and removed support for non-double-valued distance functions (in particular DoubleDistance was removed). While this reduces the generality of ELKI, we could remove about 2.5% of the codebase by not having to have optimized codepaths for double-distance anymore. Generics for distances were present in almost any distance-based algorithm, and we were also happy to reduce the use of generics this way. Support for non-double-valued distances can trivially be added again, e.g. by adding the specialization one level higher: at the query instead of the distance level, for example. In this process, we also removed the Generics from NumberVector. The object-based get was deprecated for a good reason long ago, and e.g. doubleValue are more efficient (even for non-DoubleVectors).

Dropped some long-deprecated classes.

K-means:

  • speedups for some initialization heuristics.

  • K-means++ initialization no longer squares distances (again).

  • farthest-point heuristics now uses minimum instead of sum (renamed).

  • additional evaluation criteria.

  • Elkan's and Hamerly's faster k-means variants.

CLARA clustering.

X-means.

Hierarchical clustering:

  • Renamed naive algorithm to AGNES.

  • Anderbergs algorithm (faster than AGNES, slower than SLINK).

  • CLINK for complete linkage clustering in O(n²) time, O(n) memory.

  • Simple extraction from HDBSCAN.

  • "Optimal" extraction from HDBSCAN.

  • HDBSCAN, in two variants.

LSDBC clustering.

EM clustering was refactored and moved into its own package. The new version is much more extensible.

OPTICS clustering:

  • Added a list-based variant of OPTICS to our heap-based.

  • FastOPTICS (contributed by Johannes Schneider).

  • Improved OPTICS Xi cluster extraction.

Outlier detection:

  • KDEOS outlier detection (SDM14).

  • k-means based outlier detection (distance to centroid) and Silhouette coefficient based approach (which does not work too well on the toy data sets - the lowest silhouette are usually where two clusters touch).

  • bug fix in kNN weight, when distances are tied and kNN yields more than k results.

  • kNN and kNN weight outlier have their k parameter changed: old 2NN outlier is now 1NN outlier, as commonly understood in classification literature (1 nearest neighbor other than the query object; whereas in database literature the 1NN is usually the query object itself). You can get the old result back by decreasing k by one easily.

  • LOCI implementation is now only O(n^3 log n) instead of O(n^4).

  • Local Isolation Coefficient (LIC).

  • IDOS outlier detection with intrinsic dimensionality.

  • Baseline intrinsic dimensionality outlier detection.

  • Variance-of-Volumes outlier detection (VOV).

Parallel computation framework, and some parallelized algorithms

  • Parallel k-means.

  • Parallel LOF and variants.

LibSVM format parser.

kNN classification (with index acceleration).

Internal cluster evaluation:

  • Silhouette index.

  • Simplified Silhouette index (faster).

  • Davis-Bouldin index.

  • PBM index.

  • Variance-Ratio-Criteria.

  • Sum of squared errors.

  • C-Index.

  • Concordant pair indexes (Gamma, Tau).

  • Different noise handling strategies for internal indexes.

Statistical dependence measures:

  • Distance correlation dCor.

  • Hoeffings D.

  • Some divergence / mutual information measures.

Distance functions:

  • Big refactoring.

  • Time series distances refactored, allow variable length series now.

  • Hellinger distance and kernel function.

Preprocessing:

  • Faster MDS implementation using power iterations.

Indexing improvements:

  • Precomputed distance matrix "index".

  • iDistance index (static only).

  • Inverted-list index for sparse data and cosine/arccosine distance.

  • Cover tree index (static only).

  • Additional LSH hash functions.

Frequent Itemset Mining:

  • Improved APRIORI implementation.

  • FP-Growth added.

  • Eclat (basic version only) added.

Uncertain clustering:

  • Discrete and continuous data models.

  • FDBSCAN clustering.

  • UKMeans clustering.

  • CKMeans clustering.

  • Representative Uncertain Clustering (Meta-algorithm).

  • Center-of-mass meta Clustering (allows using other clustering algorithms on uncertain objects).

Mathematics:

  • Several estimators for intrinsic dimensionality.

MiniGUI has two "secret" new options: -minigui.last -minigui.autorun to load the last saved configuration and run it, for convenience.

Logging API has been extended, to make logging more convenient in a number of places (saving some lines for progress logging and timing).
