SUPERPIXEL BASED FACTOR ANALYSIS AND TARGET TRANSFORMATION METHOD FOR MARTIAN MINERALS DETECTION
Superpixel Factor Analysis Target Transformation Minerals detection Mars
2018/5/15
The Factor analysis and target transformation (FATT) is an effective method to test for the presence of particular mineral on Martian surface. It has been used both in thermal infrared (Thermal Emissi...
Factor analysis is over a century old, but it is still problematic to choose
the number of factors for a given data set. The scree test is popular but subjective. The best performing objective method...

2009/12/3
Correctly choosing rock-breaking bit is critical in oil drilling. The optimal model of selecting a bit has been establishedbased on the Factor Analysis Theory. Through selecting primitive variables, a...
A Comparative Study of Air Quality Index Based on Factor Analysis and US-EPA Methods for an Urban Environment
Eclipsing effect Maximum operator concept (MOC) Principal component analysis (PCA) Variance, Ranking
2016/3/29
There are many different air quality indexes, which represent the global urban air pollution situation.
Although the index proposed by USEPA gives an overall assessment of air quality, it does not in...
