A Novel Machine Learning Technique to Identify and Categorize Plasma Waves in Spacecraft Measurements

نویسندگان

چکیده

The available magnetic field data from the terrestrial magnetosphere, solar wind and planetary magnetospheres exceeds over $10^6$ hours. Identifying plasma waves in these large sets is a time consuming tedious process. In this Paper, we propose solution to problem. We demonstrate how Self-Organizing Maps can be used for rapid reduction identification of sets. use 72,000 fluxgate 110,000 search coil power spectra Magnetospheric Multiscale Mission (MMS$_1$) show Map sorts into groups based on their shape. Organizing way makes it very straightforward identify with similar properties therefore technique greatly reduces need manual inspection data. suggest that offer effective robust technique, which significantly accelerate processing discovery new wave forms.

New Scheme to Identify Intrusion Outliers by Machine Learning Technique

In network administration, computers and network systems need to be protected against malicious attacks. The success of an intrusion detection system depends on the selection of the appropriate features in detecting the intrusion activity. The selection of unnecessary features may cause computational issues and reduce the accuracy of detection. In the existing work, a novel detection approach i...

willingness to communicate in the iranian context: language learning orientation and social support

why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...

Using Machine Learning to Identify Intonational Segments

The intonational phrase is hypothesized to represent a meaningful unit of analysis in spoken language interpretation. We present results on the identification of intonational phrase boundaries from acoustic features using classification and regression trees (CART). Our training and test data are taken from the Boston Directions Corpus (task-oriented monologue) and the HUB-IV Broadcast News data...

Automatic road crack detection and classification using image processing techniques, machine learning and integrated models in urban areas: A novel image binarization technique

The quality of the road pavement has always been one of the major concerns for governments around the world. Cracks in the asphalt are one of the most common road tensions that generally threaten the safety of roads and highways. In recent years, automated inspection methods such as image and video processing have been considered due to the high cost and error of manual metho...
