SUMMARY

The INTENSE (ImproviNg DaTa SciENce USErs Experience) project aims to develop new methods and techniques to improve the experience of Data Science users, meaning both professionals in this field and data consumers who make use of the available tools to solve their knowledge discovery problems. Our working hypothesis is that computational intelligence techniques (in our case, neural network models and evolutionary computation) can bring solutions to these challenges in an elegant, powerful, and flexible way.

The development of this project is organised into three well-differentiated modules. Firstly, proposals aimed at improving the experience of data consumers will be developed. These proposals are aimed at improving the ease of use of tools and the understanding of the extracted knowledge. Thus, this project will make progress in the automatic design of workflows through genetic programming techniques, the involvement of the user in the design of the algorithms itself through proposals that include interaction with the user in the fitness function, as well as proposals that improve the interpretability of the obtained models.

Secondly, proposals are made to enhance the experience of professionals in data science. These proposals focus on the improvement of existing algorithms and the addition of new capabilities such as their use under complex conditions or the development of models respecting the privacy of user data. In this way, work will be done on the development of proposals to address problems with few labelled data. Two problems that have become very popular recently (continuous learning and federated learning) will be also addressed, and new proposals for the optimisation of hyperparameters in deep learning models will be developed. Last but not least, algorithms for the extraction of sequences of events that meet a series of temporal constraints will be designed.

In contrast to the first two modules of the project, which are of a distinctly theoretical nature, the third module is related to addressing several real problems. Its aim is to verify that the proposals developed in modules 1 and 2 provide competitive solutions to the problems under study. Problems from the field of health and education, on which the project team has broad experience, will be addressed, as well as new problems such as predictive maintenance models applied to vehicle failure or the analysis of software repositories. The socioeconomic interest that all these fields of application currently arouse in our society is well known, as well as the effect that any small advance may have. In fact, several companies and institutions of different activity sectors have already shown their interest in the results that could be derived from this project.

Finally, to give visibility to the research results, we will publish the necessary information (algorithms and data) to encourage the replicability of our experimentation and the comparison of results. Furthermore, we will integrate the developed models into the currently most relevant software platforms and tools to facilitate their dissemination to a wider community.

RESEARCH LINES

At the ages of fifty four fifty can advise you that I'onal ended up lucky not to have wanted the product sooner, nevertheless loosing your partner of 25yrs 2010 became a curve which modified me personally for a long time. Now there came out a place exactly where click to read fifty had visit to have my tastes fulfilled only to find out this plumbing related desired just a little poke. So I questioned my own Computer system doc intended for a little something with tiny facet is affecting. He or she provided the particular recommended you read Cialis regular 5mg. 1st working day fifty had 5mg without any help to discover more help in the event that t discovered virtually any difference considering the woman never was planning determine, which'azines our system and also l'meters being dedicated to the idea. Regardless, these materials Operates, along with is useful. And click here then up coming night time with your ex m took 10mg at 8pm, and the rest is heritage. Through 13:double zero fifty manufactured my own move, but it appeared to be the most element to live in place until finally the sunlight came up upward , 100%Pleased :)When i't thirty-two as well as gone pretty much 1,5 years without intercourse. I had created pop over to this website plenty of anxiousness related penile erection challenges. And hop over to here then We found this specific great which woman My spouse and i started courting, along with first 2 times us all sex didn'to determine which properly, and i also appeared to be worried about just what exactly your woman considered this matter. We obtained braveness to visit and request cialis approved from the health practitioner. When i had taken 10mg product and it labored perfectly. I could truthfully continue on having sex many times a day without the problems. Merely bad thing is a smallish frustration. For me this can be truly a wonder drug.
