A Preliminary Study of SMOTE on Imbalanced Big Datasets When Dealing with Sparse and Dense High Dimensionality
(Springer, 2022-06-11)The interest in exploiting big datasets with machine learning has led to adapting classic strategies in this new paradigm determined by volume, speed, and variety. Because data quality is a determining factor in constructing ... -
Deep transfer learning for the recognition of types of face masks as a core measure to prevent the transmission of COVID-19
(2022-06-23)The use of face masks in public places has emerged as one of the most effective non-pharmaceutical measures to lower the spread of COVID-19 infection. This has led to the development of several detection systems for ... -
Estimation of Linear Regression with the Dimensional Analysis Method
(2022-05-12)Dimensional Analysis (DA) is a mathematical method that manipulates the data to be analyzed in a homogenized manner. Likewise, linear regression is a potent method for analyzing data in diverse fields. At the same time, ... -
How close can we get to the classical magnetotelluric sounding?
(2022-05-05)The classical magnetotelluric (MT) sounding can be defined as data that are invariant under rotation of coordinates -a feature we call centrality- and are affected solely by electromagnetic induction effects –a feature ... -
