AbstractThe support vector machines SVM algorithm is a popular classication technique in data mining and machine learning. In this paper, we propose a distributed SVM algorithm and demonstrate its use in a number of applications. The algorithm is named high-performance sup-port vector machines HPSVM. The major contribution of HPSVM is two-fold.
To prospect mineral deposits at regional scale, recognition and classification of hydrothermal alteration zones using remote sensing data is a popular strategy. Due to the large number of spectral bands, classification of the hyperspectral data may be negatively affected by the Hughes phenomenon. A practical way to handle the Hughes problem is preparing a lot of training samples until the size ...
This workshop is intended to bring together the Machine Learning ML, Artificial Intelligence AI and High Performance Computing HPC communities. In recent years, much progress has been made in Machine Learning and Artificial Intelligence in general. This progress required heavy use of high performance computers and accelerators.
Performance evaluation is the most important part of machine learning in my opinion. Because machine learning itself has become pretty easy because of all the libraries and packages. Anyone can develop machine learning without knowing much about what is going on behind the scene. Then performance evaluation can be a challenge.

The Ensinger Group is engaged in the development, manufacture and sale of compounds, semi-finished materials, composites, technical parts and profiles made of engineering and high-performance plastics.
To address this challenge and generate accurate, cost-effective, and in-season crop-type classification, this research uses the USDAs Common Land Units CLUs to aggregate spectral information for each field based on a time-series Landsat image data stack to largely overcome the cloud contamination issue while exploiting a machine learning model based on Deep Neural Network DNN and high-performance computing for intelligent and scalable computation of classification
Dec 22, 2018 Multiclass Classification A classification task with more than two classes e.g., classify a set of images of fruits which may be oranges, apples, or pears. Multi-class classification makes the assumption that each sample is assigned to one and only one label a fruit can be either an apple or a pear but not both at the same time.
Aug 06, 2020 Six Popular Classification Evaluation Metrics In Machine Learning. Evaluation metrics are the most important topic in machine learning and deep learning model building. These metrics help in determining how good the model is trained. We are having different evaluation metrics for a different set of machine learning algorithms.
Aug 19, 2020 Multi-Label Classification. Multi-label classification refers to those classification tasks that have two or more class labels, where one or more class labels may be predicted for each example.. Consider the example of photo classification, where a given photo may have multiple objects in the scene and a model may predict the presence of multiple known objects in the photo, such as bicycle ...
Jul 17, 2019 Supervised learning can be divided into two categories classification and regression. Classification predicts the category the data belongs to. Some examples of classification include spam detection, churn prediction, sentiment analysis, dog breed detection and so on. Regression predicts a numerical value based on previously observed data.
Jun 01, 2021 Techniques of Supervised Machine Learning algorithms include linear and logistic regression, multi-class classification, Decision Trees and support vector machines. Supervised learning requires that the data used to train the algorithm is already labeled with correct answers. For example, a classification algorithm will learn to identify ...
Aug 18, 2015 1. I understood that AUC Area Under Curve is good performance measure for imbalanced data. But, can it be used to measure classification performance for balanced data 2. I used the AUC with a Majority classiier ZeroR and got AUC 0.5. Can I say that the ZeroR classifier is
Feb 10, 2020 Actually, lets do a closer analysis of positives and negatives to gain more insight into our models performance. Of the 100 tumor examples, 91 are benign 90 TNs and 1 FP and 9 are malignant 1 TP and 8 FNs. Of the 91 benign tumors, the model correctly identifies 90 as benign. Thats good.
In general, machine learning approaches have been applied on classifying applications, security awareness, and anomaly detection. In this paper, we present a supervised machine learning approach that use On-Line Support Vector Machine and Decision Tree to classify host roles. We collect sFlow data from main gateways of a large campus network.
Summary. In the above article, we learned about the various algorithms that are used for machine learning classification.These algorithms are used for a variety of tasks in classification. We also analyzed their benefits and limitations.. The aim of this blog was to provide a clear picture of each of the classification algorithms in machine learning.
Dec 09, 2020 SVM is a supervised machine learning algorithm that helps in classification or regression problems. It aims to find an optimal boundary between the possible outputs. Simply put, SVM does complex data transformations depending on the selected kernel function and based on that transformations, it tries to maximize the separation boundaries ...
May 17, 2015 You may want to consider mixed-effects models. They are popular in social science due to their performance on high-cardinality categorical data, and I have used them to make great predictive models outperforming popular machine learning approaches like gradient boosted trees, random forests, and elastic-net regularized logistic regression.
