Montevideo, Uruguay

Uruguay is a small, beautiful and peaceful country in the subtropical region of South America. It is best known for its many beaches, its excellent meat, its passion for soccer, and its local culture which includes, among other styles, its afro-american Candombe music and its Murga musical ensembles.


Edificio Polifuncional del Faro

Facultad de Ingeniería

CIARP 2015 will be held in the Edificio Polifuncional del Faro, Facultad de Ingeniería, Universidad de la República in Montevideo, the capital city of Uruguay. Facultad de Ingeniería is located in Punta Carretas, one of Montevideo's more elegant neighborhoods, one block away from the Ramirez Beach and the Montevidean boardwalk, which spans over 20km. Various excellent restaurants and hotels are located within walking distance, making it a perfect spot for tourism and recreation within the city.



The month of November is characterized by rising daily high temperatures, with daily highs increasing from 22°C to 26°C over the course of the month, exceeding 31°C or dropping below 18°C only one day in ten.

The relative humidity typically ranges from 42% (comfortable) to 88% (very humid) over the course of a typical November, rarely dropping below 27% (dry) and reaching as high as 99% (very humid).

2014 APP award winner in Puerto Vallarta, Mexico

Dr. Luisa Micó,
Head of Department of Software and Computing Systems, Professor at the Universidad de Alicante, Spain.

Pioneer female scientist in the pattern recognition field in the Iberoamerican context, whose work focuses mainly on algorithmic aspects of the nearest neighbour search.

Nearest neighbour search is a widely used search technique. It is easy to understand, easy to adapt and, when used to classify, has very nice asymptotic properties. The major drawback is its large computational burden when large databases or costly dissimilarity measures are involved. Due of these limitations many algorithms appeared in order to overcome them. Most of those algorithms were restricted to use the euclidean distance as dissimilarity measure. Most of the other, the ones that were able to cope with any minimal adequate dissimilarity measure, were not practical since they required huge amounts of memory. Luisa Micó proposed one of the first general and practical fast nearest neighbour search algorithms and described how to adapt and improve Euclidean distance based algorithms to the general case.
