Nowadays, text classification (TC) becomes the main applications of NLP (natural language processing). Actually, we have a lot of researches in classifying text documents, such as Random Forest, Support Vector Machines and Naive Bayes. However, most of them are applied for English documents. Therefore, the text classification researches on Vietnamese still are limited. By using a Vietnamese news corpus,...
Feature extraction and classifier is crucial for content-based image retrieve and analysis. In this paper, a novel method for handwritten numeral image extraction is proposed based on Random Forest(RF) and Histogram of Oriented Gradient(HOG). The main contribution of the proposed method is to consider the advantage of HOG and RF. Further, our method extract the impactful information of image, and...
Reference evapotranspiration (ETo) is an important factor in the water-saving agriculture and in the soil-plant-atmosphere continuum. Many machine learning methods have been introduced into predicting ETo. In order to improve the accuracy of radiation-based ETo models, this paper presents an ETo model called RFR based on random forest (RF). By taking the results of FAO Penman-Monteith (FAOPM) model...
