Testimonial Laurent Favre, CEO


"We have been working with [ITC Software] for more than 2 years now. We started with contract basis work and finally came to ODC which is completely dedicated for our tasks. High team stability, good proficiency and efficient administration support are the factors which bring high value to our collaboration."  ..../more

We solve the "bottleneck" problems for people in the data analysis arena.

 


   UCI Benchmark Study

Databases with millions of records and thousands of fields are now common in business, medicine, engineering, and the sciences. The problem of extracting useful information from such data sets is an important practical problem. Research on this topic focuses on key questions such as how can one build useful descriptive models that are both accurate and understandable? Probabilistic and statistical techniques in particular, play a key role in both analyzing the inference process from a theoretical viewpoint and providing a principled basis for algorithm development. [http://www.ics.uci.edu/~mlearn/Machine-Learning.html]

Our main focus is to help people understand data  (multidimensional and spatial) when they have no idea about the  data structure and dependency -  an area of data mining and  exploratory data analysis.

We are a small unclear-problem-oriented team, using the same  means in various domains, trying to solve problems having  inefficient solutions or not having known solutions at all:

- Multidimensional data exploratory analysis and visualization:

 

Remote-sensed data (RS), multi-source images, scientific, sociological, medical, ...  The task usually is not to test known hypothesis, but to generate new ones from huge amounts of very noisy unstructured data in order to discover data dependencies using statistical and "exoteric" means (like Kohonen neural nets SOM - they produce pretty pictures representing data and are useful for interpretation by domain specialists.)

 

- Multidimensional (including spatio-temporal and economic) data analysis, modeling and prediction using "black-box" models (where no information about the object's internal structure is available):

 

Various regressions, Artificial Neural Networks (ANN), fuzzy logic, expert systems, etc. For example, the EUNITE Website (European Network of Excellence on Intelligent Technologies for Smart Adaptive Systems) >  has a short description of the Competition Team (we were participants) on glass manufacturing melting tank modeling>

In spatial data processing we combine (GIS) technics; geostatistics: variography, kriging, splines(contextual) Kohonen neural networks (SOM) and stochastic spatial models (Gaussian and Markov Random Field - MRF) providing a means of estimating and mapping of various spatial gradients and ecotones using multidimensional sets of features.

The main reason for using SOM and other topographic mapping techniques in data analysis (not only spatial) is that it combines data classification and ordination, and could be used in data mining and exploratory data analysis to discover data structures, especially if the data is of a continuous nature and can not be separated into discrete classes - almost all natural data is of this kind.

  • For example, NeRIS software, utilizing SOM and MRF, was used for the creation of the Atlas of Russia’s Intact Forest using RS data, and allowed to process the full RS coverage for Russia and represent all results using the same legend (Aksenov et al., Atlas of Russia’s Intact Forest Landscapes, Moscow: 2002, 186p.).

  • Another example is the application of ANN (Artificial Neural Networks) in water quality assessments based on a set of indirect tests, where ANN models were compared with traditional statistical approaches (see references).

In these areas we develop proper "technology chains" from available modules for the task at hand, rather than "end-user" software.


Project Examples:

  • Benchmark Study for the University of California Irvine (UCI) Machine Learning Repository: Prediction of persons with more then $50K income based on U.S. Census Bureau data >
     

  • We worked for geologists and issued 2-3 Technical Reports per year (unpublished) concerning subterranean water (geological horizon geometry modeling; estimation of spatial distribution of water quality and contamination).
     

  • Another big project we were involved in for 5 years was the estimation of the anthropogenic load on the environment in the surrounding area of a big oil company's activity.  A few hundred component-wise estimations (air, soil, ...) were combined by various means, including neural nets, producing integrated estimations of the environment state and stress.
     

  • We have also developed efficient image processing and 3D visualization software (the last one was a real-time flight simulator based on remote sensed data).
     

  • Our largest project was the development of RS (Remote Sensed) image processing software for the R&D Center of ScanEx. The project is described on Scanex' Website >> We are involved in Scanex Image Processor and Scanex NeRIS (Neural Raster Image Processor) development.
