Road Network Deterioration Monitoring Using Aerial Images and Computer Vision
Nicolas Parra-A, Vladimir Vargas-Calderón, Herbert Vinck-Posada +1
Road maintenance is an essential process for guaranteeing the quality of transportation in any city. A crucial step towards effective road maintenance is the ability to update the…
An Empirical Study of Quantum Dynamics as a Ground State Problem with Neural Quantum States
Vladimir Vargas-Calderón, Herbert Vinck-Posada, Fabio A. González
We consider the Feynman-Kitaev formalism applied to a spin chain described by the transverse field Ising model. This formalism consists of building a Hamiltonian whose ground state…
Optimisation-free Classification and Density Estimation with Quantum Circuits
Vladimir Vargas-Calderón, Fabio A. González, Herbert Vinck-Posada
We demonstrate the implementation of a novel machine learning framework for probability density estimation and classification using quantum circuits. The framework maps a training…
Dark Exciton Giant Rabi Oscillations with no External Magnetic Field
Vladimir Vargas-Calderón, Herbert Vinck-Posada, J. M. Villas-Boas
Multi-phonon physics is an emerging field that serves as a test bed for fundamental quantum physics and several applications in metrology, on-chip communication, among others. Quan…
Machine learning for assessing quality of service in the hospitality sector based on customer reviews
Vladimir Vargas-Calderón, Andreina Moros Ochoa, Gilmer Yovani Castro Nieto +1
The increasing use of online hospitality platforms provides firsthand information about clients preferences, which are essential to improve hotel services and increase the quality…
Many-Qudit representation for the Travelling Salesman Problem Optimisation
Vladimir Vargas-Calderón, Nicolas Parra-A., Herbert Vinck-Posada +1
We present a map from the travelling salesman problem (TSP), a prototypical NP-complete combinatorial optimisation task, to the ground state associated with a system of many-qudits…
Learning with Density Matrices and Random Features
Fabio A. González, Alejandro Gallego, Santiago Toledo-Cortés +1
A density matrix describes the statistical state of a quantum system. It is a powerful formalism to represent both the quantum and classical uncertainty of quantum systems and to e…
Towards robust and speculation-reduction real estate pricing models based on a data-driven strategy
Vladimir Vargas-Calderón, Jorge E. Camargo
In many countries, real estate appraisal is based on conventional methods that rely on appraisers' abilities to collect data, interpret it and model the price of a real estate prop…
Learning from students' perception on professors through opinion mining
Vladimir Vargas-Calderón, Juan S. Flórez, Leonel F. Ardila +3
Students' perception of classes measured through their opinions on teaching surveys allows to identify deficiencies and problems, both in the environment and in the learning method…
A model for predicting price polarity of real estate properties using information of real estate market websites
Vladimir Vargas-Calderón, Jorge E. Camargo
This paper presents a model that uses the information that sellers publish in real estate market websites to predict whether a property has higher or lower price than the average p…
Event detection in Colombian security Twitter news using fine-grained latent topic analysis
Vladimir Vargas-Calderón, Nicolás Parra-A., Jorge E. Camargo +1
Cultural and social dynamics are important concepts that must be understood in order to grasp what a community cares about. To that end, an excellent source of information on what…
Light emission properties in a double quantum dot molecule immersed in a cavity: phonon-assisted tunneling
Vladimir Vargas-Calderón, Herbert Vinck-Posada
Two main mechanisms dictate the tunneling process in a double quantum dot: overlap of excited wave functions, effectively described as a tunneling rate, and phonon-assisted tunneli…
Phonon-assisted tunnelling in a double quantum dot molecule immersed in a cavity
Vladimir Vargas-Calderón, Herbert Vinck-Posada
The effects caused by phonon-assisted tunnelling (PhAT) in a double quantum dot (QD) molecule immersed in a cavity were studied under the quantum Markovian master equation formalis…
Experimental study of elastic properties of noodles and bucatini
Vladimir Vargas-Calderón, A. F. Guerrero-González, F. Fajardo
The mechanical behaviour of two types of pasta (noodles and bucatini) was studied in a cantilever-loaded-at-the-end experimental setup. One end of each pasta was fixed while the ot…
