  • Automatically identifying sufficient object builders from Module APIs 

    Ponzio, Pablo; Bengolea, Valeria; Politano, Mariano; Aguirre, Nazareno; Frías, Marcelo (2019)
    "Various approaches to software analysis (e.g. test input generation, software model checking) require engineers to (manually) identify a subset of a module’s methods in order to drive the analysis. Given a module to be ...
  • SAR Image segmentation based on multifractal features 

    Pacheco, Cristian; Gambini, Juliana; Delrieux, Claudio (2019-09)
    "Synthetic Aperture Radar (SAR) imaging is based on airborne or satellite active microwave sensors that can capture the earth surface by emitting a signal and receiving the backscattered signal that forms the resulting ...
  • Training binary classifiers as data structure invariants 

    Molina, Facundo; Degiovanni, Renzo; Ponzio, Pablo; Regis, Germán; Aguirre, Nazareno; Frías, Marcelo (2019-05)
    "We present a technique to distinguish valid from invalid data structure objects. The technique is based on building an artificial neural network, more precisely a binary classifier, and training it to identify valid and ...
  • Topotecan penetration assessment in retinoblastoma cells using Shannon entropy and coefficient of variation 

    Howlin, Marcelo; Chan, Debora; Ramele, Rodrigo; Gambini, Juliana (2019-09)
    "Retinoblastoma is a common intraocular tumor of childhood. One of the medications used as an antineoplastic agent for retinoblastoma treatment is topotecan. Its penetration into living tumorspheres is quantified using ...
  • DynAlloy analyzer: a tool for the specification and analysis of Alloy models with dynamic behaviour

    "We describe DynAlloy Analyzer, a tool that extends Alloy Analyzer with support for dynamic elements in Alloy models. The tool builds upon Alloy Analyzer in a way that makes it fully compatible with Alloy models, and extends ...
  • An analysis of the suitability of test-based patch acceptance criteria 

    Zemín, Luciano; Gutiérrez Brida, Simón; Godio, Ariel; Cornejo, César; Degiovanni, Renzo; Regis, Germán; Aguirre, Nazareno; Frías, Marcelo (2017-07)
    "Program repair techniques attempt to fix programs by looking for patches within a search space of fix candidates. These techniques require a specification of the program to be repaired, used as an acceptance criterion for ...
  • Performing OLAP over graph data: query language, implementation, and a case study 

    Gómez, Leticia Irene; Kuijpers, Bart; Vaisman, Alejandro Ariel (2017-08)
    "In current Big Data scenarios, traditional data warehousing and Online Analytical Processing (OLAP) operations on cubes are clearly not sufficient to address the current data analysis requirements. Nevertheless, OLAP ...
  • Methods and frameworks for sampling 𝒢I0 data 

    Chan, Debora; Rey, Andrea; Gambini, Juliana; Cassetti, Julia; Frery, Alejandro C. (2017)

  • Outliers resistant methods for motor imagery classification 

    Villar, Ana Julia (2018-08)
    "Common spatial patterns analysis (CSP) and linear discriminant analysis (LDA) are widely used techniques for spatial filtering and classifying in motor imagery (MI). However, CSP is very sensitive to noise and artifacts. ...
  • From operational to declarative specifications using a genetic algorithm 

    Molina, Facundo; Degiovanni, Renzo; Regis, Germán; Castro, Pablo; Aguirre, Nazareno; Frías, Marcelo (2018-05)
