In this paper, we investigate the performance and success rates of Naïve Bayes Classification Algorithm for automatic classification of Turkish news into predetermined categories like economy, life, health etc. We use Apache Big Data technologies such as Hadoop, HDFS, Spark and Mahout, and apply these distributed technologies to Machine Learning. Keywords—news classification, distributed machin...

A census of massive galaxies at redshift increasingly higher than z ∼ 1 may provide strong constraints on the history of mass assembly and of star formation. Here we report the analysis of three galaxies selected in the Hubble Deep Field South at Ks≤ 22 on the basis of their unusually red near-IR color J-K≥ 3. We have used population synthesis models to constrain their redshifts and their stell...

Data analysis is very important for the success of any business today. It helps to optimize processes, analyze users’ behavior, demands etc. There are powerful data analytics tools, such as ones Hadoop ecosystem, but they require multiple high-performance servers run and high-qualified experts install, configure support them. In most cases, small companies start-ups could not afford expenses. H...

This paper describes Ivory, an attempt to build a distributed retrieval system around the open-source Hadoop implementation of MapReduce. We focus on three noteworthy aspects of our work: a retrieval architecture built directly on the Hadoop Distributed File System (HDFS), a scalable MapReduce algorithm for inverted indexing, and webpage classification to enhance retrieval effectiveness.

BACKGROUND Adipose-derived stem cells (ADSCs) are a population of pluripotent cells, which have characteristics similar to bone marrow-derived mesenchymal stem cells. Whereas ADSCs have potential applications for the repair and regeneration of various damaged tissues, few studies have dealt with the effect of ADSCs on fibroblasts, which play a key role in skin biology. OBJECTIVE In this study...

For the past 20 years, super-oxidised solutions (SOSs) have been shown to be potent antimicrobials and disinfectants via oxidative damage. However, the potential toxicity of SOSs on eukaryotic cells has not been documented in vitro. This is relevant because oxygen and chlorine reactive species may possibly induce ageing and irreversible cellular dysfunctions that eventually produce cell death. ...
