Feature Selection - General L1-norm Support Vector Machine For Feature Selection

General L1-norm Support Vector Machine For Feature Selection

It has been shown in that the traditional L1-norm SVM proposed by Bradley and Mangasarian in can be generalized to a general L1-norm SVM (GL1-SVM).

Moreover, it has been proved that solving the new proposed optimization problem (GL1-SVM) gives smaller error penalty and enlarges the margin between two support vector hyper-planes, thus possibly gives better generalization capability of SVM than solving the traditional L1-norm SVM.

GL1-SVM may also be seen a special case of some generic feature selectors.

Famous quotes containing the words general, support, machine, feature and/or selection:

    The man who would change the name of Arkansas is the original, iron-jawed, brass-mouthed, copper-bellied corpse-maker from the wilds of the Ozarks! He is the man they call Sudden Death and General Desolation! Sired by a hurricane, dam’d by an earthquake, half-brother to the cholera, nearly related to the smallpox on his mother’s side!
    —Administration in the State of Arka, U.S. public relief program (1935-1943)

    Every winter the liquid and trembling surface of the pond, which was so sensitive to every breath, and reflected every light and shadow, becomes solid to the depth of a foot or a foot and a half, so that it will support the heaviest teams, and perchance the snow covers it to an equal depth, and it is not to be distinguished from any level field. Like the marmots in the surrounding hills, it closes its eyelids and becomes dormant for three months or more.
    Henry David Thoreau (1817–1862)

    Goodbye, boys; I’m under arrest. I may have to go to jail. I may not see you for a long time. Keep up the fight! Don’t surrender! Pay no attention to the injunction machine at Parkersburg. The Federal judge is a scab anyhow. While you starve he plays golf. While you serve humanity, he serves injunctions for the money powers.
    Mother Jones (1830–1930)

    The proclamation and repetition of first principles is a constant feature of life in our democracy. Active adherence to these principles, however, has always been considered un-American. We recipients of the boon of liberty have always been ready, when faced with discomfort, to discard any and all first principles of liberty, and, further, to indict those who do not freely join with us in happily arrogating those principles.
    David Mamet (b. 1947)

    When you consider the radiance, that it does not withhold
    itself but pours its abundance without selection into every
    nook and cranny
    Archie Randolph Ammons (b. 1926)
