Machine learning in APOGEE: Unsupervised spectral classification with K-means
Context. The data volume generated by astronomical surveys is growing rapidly. Traditional analysis techniques in spectroscopy either demand intensive human interaction or are computationally expensive. In this scenario, machine learning, and unsupervised clustering algorithms in particular offer interesting alternatives. The Apache Point Observatory Galactic Evolution Experiment (APOGEE) offer...
متن کاملStudy of Physical Characteristics of High Apogee Space Debris
Data acquisition and analysis methods of medium to high apogee space debris (MHASD)’s optical characteristics are discussed in this paper.
متن کاملHigh-confidence assessment of functional impact of human mitochondrial non-synonymous genome variations by APOGEE
24,189 are all the possible non-synonymous amino acid changes potentially affecting the human mitochondrial DNA. Only a tiny subset was functionally evaluated with certainty so far, while the pathogenicity of the vast majority was only assessed in-silico by software predictors. Since these tools proved to be rather incongruent, we have designed and implemented APOGEE, a machine-learning algorit...
متن کاملDesign of FIR filter using hanning window, hamming window and modified hamming window
Digital filters are widely used in many digital signal processing applications. Therefore, digital filtering is one of the basic needs of digital signal processing. This paper introduces the definition and basic principles of FIR digital filters, and the design based on MATLAB.After the description of the process of design, the matlab program is used to implement FIR filter using modified coeff...
متن کاملDocument Analysis And Classification Based On Passing Window
In this paper we present Document analysis and classification system to segment and classify contents of Arabic document images. This system includes preprocessing, document segmentation, feature extraction and document classification. A document image is enhanced in the preprocessing by removing noise, binarization, and detecting and correcting image skew. In document segmentation, an algorith...
