概括
反对训练提高了强度,但损害了概括性. 本研究引入了注意力增强学习框架 (AELF),通过在强度训练期间规范空间注意力模式来保持概括性.
科学领域:
- 深度学习 (Deep Learning) 是一种深度学习.
- 计算机视觉 计算机视觉
- 机器学习 机器学习
背景情况:
- 对抗性训练提高了深度模型的稳定性,但通常会导致自然数据的概括性-性能权衡.
- 这种现象与对抗性培训有关,导致模型专注于稀疏的地区,忽视了更广泛的歧视性信息.
研究的目的:
- 在对抗性训练中解决泛化-稳健性权衡问题.
- 提出一个注意力增强学习框架 (AELF),它保留了标准的概括,同时提高了对抗性强度.
主要方法:
- 研究了空间注意力对一般化-强度权衡的影响.
- 引入了一种嵌入级规范化技术,使用预先训练的教师模型的注意力模式.
- 开发了一个简化的AELF,使用参数初始化和更新策略与交叉损失.
主要成果:
- 证明对抗性训练可以导致过度集中在稀疏的空间区域上,阻碍了概括.
- 实验结果表明,在高水平的对抗性稳定性下,AELF显著提高了概括性能.

Confirmation Biases
5.5K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
