Fruit Classification using Colorized Depth Images

Dhong Fhel K. Gom-os Abstract Fruit classification is a computer vision task that aims to classify fruit classes correctly, given an image. Nearly all fruit classification studies have used RGB color images as inputs, a few have used costly hyperspectral images, and a few classical ML-based have used colorized depth images. Depth images have apparent benefits such as invariance to lighting, less storage requirement, better...

On Dual B-Topological Spaces Determined by Filterbase and Some Sets in a Dual B-algebra

Jimboy Ruben AlbaracinKatrina E. Belleza Abstract This paper presents dual B-topologies that are determined by filterbase and some sets in a dual B-algebra. Also, some properties of a filterbase in a dual B-topological space are provided. In particular, a commutative dual B-topological space and a symmetric B-topological space are topological dual B-algebras. Keywords:  topological algebra, dual B-algebra, topological B-algebra, dual...

A new univariate feature selection algorithm based on the best–worst multi-attribute decision-making method

Dharyll Prince M. Abellana, Demelo M. Lao Abstract With the extensive applicability of machine learning classification algorithms to a wide spectrum of domains, feature selection (FS) becomes a relevant data preprocessing technique due to the high dimensionality of data used in these domains. While efforts have been made to study various filters for ranking features, scholars have paid little attention to developing a unified framework that can...

Sisyphean Cycle of Duterte’s
Environmental Management

Marie Rose Arong IntroductionRodrigo Duterte’s candidacy may have been officially announced in lateNovember 2015 but his rise in popularity, in the Visayas at least, was aidedby the dismal performance of then President Benigno Aquino’s administration when super typhoon Haiyan (known locally as Yolanda) struck the Mindanao and Visayas regions on November 7, 2013. A few days after the typhoon, Duterte visited Tacloban and offered “P8 million...

Indoor Pollutant Classification Modeling using Relevant Sensors under Thermodynamic Conditions with Multilayer Perceptron Hyperparameter Tuning

 Percival J. Forcadilla Abstract Air pollutants that are generated from indoor sources such as cigarettes, cleaning products, air fresheners, etc. impact human health. These sources are usually safe but exposure beyond the recommended standards could be hazardous to health. Due to this fact, people started to use technology to monitor indoor air quality (IAQ) but have no capability of recognizing pollutant sources. This research is an...

Characteristics of Marine Heatwaves in the Philippines

Brisneve Edullantes a1, Brenna Mei M. Concolis a1, Raven Quilestino-Olario a1, Dale Patrick D. Atup a, Aiza Cortes a, Aletta T. Yñiguez b Abstract Marine Heatwaves (MHWs) are prolonged, discrete, and anomalously warm events, which have recently gained global attention due to their far-reaching effects and reported impacts. Although intensive studies have been carried out at global and regional scales, these events remained understudied in the...
