Characterization of climatological time series using autoencoders
(Universidad La Salle, 2017-11-08)
Common problems in climatological time series data are high dimensionality, correlation between the sequential values and noise due to calibration of meteorological stations influencing dramatically in the quality of ...
On Semantic Solutions for Efficient Approximate Similarity Search on Large-Scale Datasets
(Universidad La Salle, 2018-07-04)
Approximate similarity search algorithms based on hashing were proposed to query high-dimensional datasets due to its fast retrieval speed and low storage cost. Recent studies, promote the use of Convolutional Neural Network ...
Developing a Holistic Understanding of Systems and Algorithms through Research Papers
(Universidad La Salle, 2017-07-03)
Even though a computer science degree is unavoidably broken into semesters and courses, we always hope that our students form a holistic picture of the discipline by the time they graduate. Yet as educators, we do not have ...
