A Computational Perspective on Visual Attention

A Computational Perspective on Visual Attention

Preface

Attention 竟然也会有 起落:70 年代中期的时候,由于计算资源极其有限,Attention 作为一个可以聚焦、节省资源的方式得到了很大的关注;但到了 80 年代,Attention 变得很冷了,因为人们不相信 Attention。现在 Attention 变得更受关注了。本书出版于 2011 年,作者肯定想不到在深度学习统治的现在,Attention 更火了。

这帮认知、AI 交叉的人感兴趣的都是 develop models and systems that are biologically plausible

attention 通常要么被认为是 **selection of a region of interest to guide eye movements **要么被认为是 single-neuron modulation,看作者的意思是这两者是相关的,会有一个 overarching theory of attention 将两者统一起来。

1. Attention—We All Know What It Is

But Do We Really?

Attention 是共同受 sensory 和 intellectual 影响的

Helmholtz (1860)认为 Attention 是 unconscious inference;与之相反,Panum (1858) believed that attention is an activity entirely subservient to an observer’s conscious will

关于解释 Attention 的理论有很多:

  1. Early Selection (Broadbent, 1958),
  2. using Attenuator Theory (Treisman, 1964)
  3. a Late Selection process (Deutsch & Deutsch, 1963; MacKay, 1973; Moray, 1969; Norman, 1968)
  4. a two-part process, preattentive followed by attentive processing (Neisser, 1967)
  5. as a result of neural synchrony (Milner, 1974), using the metaphor of a spotlight (Shulman, Remington, & McLean, 1979)
  6. within Feature Integration Theory (Treisman & Gelade, 1980),
  7. as an object-based phenomenon (Duncan, 1984),
  8. as a shrink-wrap process (Moran & Desimone, 1985),
  9. using the Zoom Lens metaphor (Eriksen & St. James, 1986),
  10. as a Premotor Theory subserving eye movements (Rizzolatti, Riggio, Dascola, & Umilta, 1987),
  11. as Guided Search (Wolfe, Cave, & Franzel, 1989),
  12. as Biased Competition (an extension of the shrink-wrap interpretation; Desimone & Duncan, 1995),
  13. as Feature Similarity Gain (Treue & Martinez-Trujillo, 1999)
