Estimating defection in subscription-type markets: empirical analysis from the scholarly publishing industry
Michael Roberts, J. Ignacio Deza, Hisham Ihshaish +1
We present the first empirical study on customer churn prediction in the scholarly publishing industry. The study examines our proposed method for prediction on a customer subscrip…
Integrating wind variability to modelling wind-ramp events using a non-binary ramp function and deep learning models
Russell Sharp, Hisham Ihshaish, J. Ignacio Deza
The forecasting of large ramps in wind power output known as ramp events is crucial for the incorporation of large volumes of wind energy into national electricity grids. Large var…
A Machine Learning Approach to Classifying Construction Cost Documents into the International Construction Measurement Standard
J. Ignacio Deza, Hisham Ihshaish, Lamine Mahdjoubi
We introduce the first automated models for classifying natural language descriptions provided in cost documents called "Bills of Quantities" (BoQs) popular in the infrastructure c…
Task-oriented Dialogue Systems: performance vs. quality-optima, a review
Ryan Fellows, Hisham Ihshaish, Steve Battle +3
Task-oriented dialogue systems (TODS) are continuing to rise in popularity as various industries find ways to effectively harness their capabilities, saving both time and money. Ho…
qNoise: A generator of non-Gaussian colored noise
J Ignacio Deza, Hisham Ihshaish
We introduce a software generator for a class of colored (self-correlated) and non-Gaussian noise, whose statistics and spectrum depend on two parameters, and . Inspired by…
Piezoelectric energy harvesting from colored fat-tailed fluctuations: An electronic analogy
J. I. Peña Rosselló, R. R. Deza, J. I. Deza +1
Aiming to optimize piezoelectric energy harvesting from strongly colored fat-tailed fluctuations, we have recently studied the performance of a monostable inertial device under a n…
Assessing the direction of climate interactions by means of complex networks and information theoretic tools
J. Ignacio Deza, Cristina Masoller, Marcelo Barreiro
An estimate of the net direction of climate interactions in different geographical regions is made by constructing a directed climate network from a regular latitude-longitude grid…
Distinguishing the effects of internal and forced atmospheric variability in climate networks
J. Ignacio Deza, Cristina Masoller, Marcelo Barreiro
The fact that the Earth climate is a highly complex dynamical system is well-known. In the last few decades a lot of effort has been focused on understanding how climate phenomena…
