A configurable strategy for extraction, transformation and load to support data propagation on active data warehouses
(2017-06-07)
This work consists of the construction of a strategy called ETL-PoCon to execute Extraction, Transformation and Load (ETL) processes in active Data Warehouses (DW) with a configurable policy. The original contribution of ...
How optimizing perplexity can affect the dimensionality reduction on word embeddings visualization?
(Springer, 2019-12-01)
Traditional word embeddings approaches, such as bag-of-words models, tackles the problem of text data representation by linking words in a document to a binary vector, marking their occurrence or not. Additionally, a term ...
Radar Noise Reduction Based on Binary Integration
(IEEE, 2015)
Short range radars can provide robust information
about their surroundings under atmospheric disturbances,
such as dust, rain, and snow, conditions under which most
other sensing technologies fail. However, this information ...
On data reduction methods for volcanic tremor characterization: the 2012 eruption of Copahue volcano, Southern Andes
(Terra Scientific Publishing, 2020-12)
Improving the ability to detect and characterize long-duration volcanic tremor is crucial to understand the long-term dynamics and unrest of volcanic systems. We have applied data reduction methods (permutation entropy and ...
