A2. Dimensionality reduction as feature selection or feature extraction: I'll use the ubiquitous Iris dataset, which is arguably the 'hello world' of data science. Briefly, the Iris dataset has 3 classes and 4 attributes (columns). I'll illustrate feature selection and extraction for the task of reducing Iris dataset dimensionality from 4 to 2.

Selection of optimal features is an important area of research in medical data mining systems. Principal component analysis (PCA) is one among the most popular feature selection methods. Still PCA faces a drawback – i.e., the measurements from all of the original features are used in the projection to the lower dimensional space.

Determining Sand Pack Size | 2003-01-28 | National Driller

Jan 28, 2003 · Selecting the appropriate sand pack can be a challenge. Thomas Kwader presents some guidelines for making your choice. Generally, a well functions as a monitor or as a pumping or production well. If the well is completed with a screen, as opposed to an open hole finish in hard rock, then the screen usually is surrounded by a sand pack placed by the driller.

Oil Sands Extraction and Processing - nrcan.gc.ca

Currently, 20% of oil sands reserves are accessible via mining techniques. Large shovels scoop the oil sand into trucks which then move it to crushers where the large clumps of earth are processed. Once the oil sand is crushed, hot water is added so it can be pumped to the extraction plant.

Sand and Gravel | Minerals Education Coalition

Sand and Gravel. Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO 2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away.
