Absent Assessment

Absent Multiple Kernel Learning

Multiple kernel learning (MKL) optimally combines the multiple channels of each sample to improve classification performance. However, existing MKL algorithms cannot effectively handle the situation where some channels are missing, which is common in practical applications. This paper proposes an absent MKL (AMKL) algorithm to address this issue. Different from existing approaches where missing...

The Absent-Minded Driver

The example of the ‘‘absent-minded driver’’ was introduced by Piccione and Rubinstein in the context of games and decision problems with imperfect recall. They claim that a ‘‘paradox’’ or ‘‘inconsistency’’ arises when the decision reached at the ‘‘planning stage’’ is compared with that at the ‘‘action stage.’’ Though the example is provocative and worth having, their analysis is questionable. A...

Absent at Birth

Patient presentation: An otherwise healthy 29-year-old white woman presented to our emergency department with leg pain and edema. She was well until 2 weeks before, when she developed lower back pain following a 3-hour flight. Her pain progressed despite treatment with ice packs, nonsteroidal anti-inflammatory drugs, and stretching, and it became so severe that she was unable to sit comfortably...

Protein Folding Absent Selection

Biological proteins are known to fold into specific 3D conformations. However, the fundamental question has remained: Do they fold because they are biological, and evolution has selected sequences which fold? Or is folding a common trait, widespread throughout sequence space? To address this question arbitrary, unevolved, random-sequence proteins were examined for structural features found in f...
