    • An Enhanced Texture-Based Feature Extraction Approach for Classification of Biomedical Images of CT-Scan of Lungs 

      Srivastava, Varun; Gupta, Shilp; Chaudhary, Gopal; Balodi, Arun; Khari, Manju; García-Díaz, Vicente (International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 09/2021)
      Content Based Image Retrieval (CBIR) techniques based on texture have gained a lot of popularity in recent times. In the proposed work, a feature vector is obtained by concatenation of features extracted from local mesh ...

    • Automatic Discovery of Complementary Learning Resources 

      Romero Zaldivar, Vicente Arturo; Crespo García, Raquel M; Burgos, Daniel ; Delgado Kloos, Carlos; Pardo, Abelardo (Towards Ubiquitous Learning. EC-TEL 2011, 2011)
      Students in a learning experience can be seen as a community working simultaneously (and in some cases collaboratively) in a set of activities. During these working sessions, students carry out numerous actions that affect ...

    • Clustering aglomerativo para la desambiguación de nombres de autor 

      Padilla-Mesa, Juan Antonio (09/2021)
      La ambigüedad de los nombres de autor en las bases de datos bibliográficas supone un gran problema a la hora de la recuperación de información, la realización de análisis bibliométricos y la visibilidad de la ciencia. Esto ...

    • Motivic Pattern Classification of Music Audio Signals Combining Residual and LSTM Networks 

      Arronte Alvarez, Aitor; Gómez, Francisco (International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 06/2021)
      Motivic pattern classification from music audio recordings is a challenging task. More so in the case of a cappella flamenco cantes, characterized by complex melodic variations, pitch instability, timbre changes, extreme ...
