Model selection for support-vector machines through metaheuristic optimization algorithms

Oumeima Ghnimi, Sofiane Kharbech, Akram Belazi, Ammar Bouallegue

A machine learning algorithm aims at designing a mathematical model based on a given training data set. Generally, the built model has a set of parameters that need to be adjusted. Since the performance of a given model depends on its settings, the parameters have to be carefully chosen through a...

SERS characterization of aggregated and isolated bacteria deposited on silver-based substrates

Cristina-Cassiana Andrei, Anne Moraillon, Eric Larquet, Monica Potara, Simion Astilean, Endre Jakab, Julie Bouckaert, Léa Rosselle, Nadia Skandrani, Rabah Boukherroub, Francois Ozanam, Sabine Szunerits, Anne Chantal Gouget-Laemmel

Surface-enhanced Raman scattering (SERS), based on the enhancement of the Raman signal of molecules positioned within a few nanometres from a structured metal surface, is ideally suited to provide bacterial-specific molecular fingerprints which can be used for analytical purposes. However, for some...

Third order notch over multi-bias and temperature in GaN and GaAs HEMTs

M.A. Alim, A.A. Rezazadeh, Christophe Gaquière

A detailed study about the shifting of third-order notch and threshold voltage with temperature for GaN and GaAs FETs were analyzed. For this purpose, a great deal of data over temperature between-40 to 150°C were measured by using two-tone intermodulation distortion set up. It was found that the...

Consequences of antenna effects on s-SNOM imaging of a photonic mode

T Hannotte, Louis Thomas, C Nascimento Santos, M Lavancier, Sophie Eliet, B Walter, Marc Faucher, Jean-Francois Lampin, Romain Peretti

We report on the influence of antenna effects on the imaging by THz s-SNOM of a photonic mode. Unknown radiation pattern from the probe and sample combination makes the interpretation of a s-SNOM image non-trivial.

Joint modeling of received power, mean delay, and delay spread for wideband radio channels

Ayush Bharti, Ramoni Adeogun, Xuesong Cai, Wei Fan, Francois-Xavier Briol, Laurent Clavier, Troels Pedersen

We propose a multivariate log-normal distribution to jointly model received power, mean delay, and root mean square (rms) delay spread of wideband radio channels, referred to as the standardized temporal moments. The model is validated using experimental data collected from five different...
