We investigate the use and performance of the quasi-static memdiode model (QMM) when incorporated into large cross-point arrays intended for pattern classification tasks. Following Chua's memristive devices theory, the QMM comprises two equations, one equation for the electron transport based on the double-diode circuit with single series resistance and a second equation for the internal memory state of the device based on the so-called logistic hysteron or memory map.

Departament de Química) ; Pérez, Sandra (Centro Nacional de Microelectrónica) ; Prieto-Simón, Beatriz (Universitat Rovira i Virgili. Departament d'Enginyeria Electrònica, Elèctrica i Automàtica)
Electronic tongues (ETs) are bioinspired analytical tools based on the synergies between (bio)sensors and chemometrics. Through the application of chemometrics, it is possible to infer underlying relationships between the measured analytical signals and the chemical properties of the samples, both for descriptive and predictive purposes, otherwise impossible to decipher.

18 p, 498.2 KB An Efficient BoF Representation for Object Classification / Vinoharan, Veerapathirapillai (University of Jaffna) ; Ramanan, Amirthalingam (University of Jaffna, Department of Computer Science)
The Bag-of-features (BoF) approach has proved to yield better performance in a patch-based object classification system owing to its simplicity. However, often the very large number of patch-based descriptors (such as scale-invariant feature transform and speeded up robust features, extracted from images to create a BoF vector) leads to huge computational cost and an increased storage requirement.
