The Segmented and Annotated IAPR TC-12 Benchmark


Sample image from the SAIAPR TC12 collection

An image collection composed of 20,000 images that have been manually segmented and annotated. This benchmark is intended for the evaluation of region labeling methods and for studying the impact of automatic image annotation in the task of multimedia image retrieval.

The resource comprises ~100,000 labeled regions, visual features extracted from the regions, spatial relationships between regions, segmentation masks and regions labeled with a conceptual hierarchy. The SAIAPR TC12 collection is publicly available for research purposes from this link.

Important: Because of its size, the benchmark has been divided and compressed into 3 files (using winrar®), please follow the following instructions:
1.- download the following three files:

We are very grateful with Thomas Deselaers for his support on the storage and management of the data.

2.- copy these *.rar files into a directory
3.- unpack the first part-file saiaprtc12ok.part1.rar using winrar® or your preferred software.

Particle Swarm Model Selection


Particle Swarm Model Selection (PSMS) is a tool for the automatic selection of full classification models; where a full model is that composed of methods for data preprocessing, feature selection and classification. PSMS searches the space of full models that can be generated with a machine learning toolbox with the goal of minimizing the (cross-validation) missclassification error rate. PSMS uses particle swarm optimization for exploring such a search space.

PSMS is currently implemented in the CLOP toolbox (an outdated version of PSMS is distributed with CLOP). It has been successfully applied in several domains, including the data sets considered in the ALvsPK machine learning challenge.

Download

  • The implementation of PSMS described in the JMLR paper can be downloaded from this link.
  • The latest PSMS implementation can be downloaded from this link.
  • See the resource EPSMS above (under construction!) for the PSMS implementation that can be used for generating ensembles.

GRASP with Path Relinking for the Commercial Territory Design Problem


We (Roger Ríos and myself) provide the Matlab code we developed for the commercial territory design (CTD) problem. We proposed a GRASP heuristic augmented with Path Relinking for the CTD problem. The data and code are from this link.

This work was done while I was a assistant professor at PISIS - UANL, in close collaboration with Roger Ríos Mercado.
