背景情况:
- 牙磨牙或牙的特征是牙磨牙或牙,可以与牙接触相关,也可以没有牙接触.
- 准确地分类不同的布鲁克斯运动对于诊断和管理至关重要.
- 电肌图 (EMG) 和声音数据为检测布鲁克斯症事件提供了潜在的生物标志物.
研究的目的:
- 评估机器学习算法在自动分类电肌图 (EMG) 数据中的有效性.
- 为了区分与牙接触 (BMwTC) 的布鲁克西斯模拟运动,没有牙接触的布鲁克西斯模拟运动 (BMwoTC) 和非布鲁克西斯运动 (非BM).
- 评估单流和多流隐藏马尔科夫模型 (HMM) 的性能,用于自动化布鲁克斯主义分类.
主要方法:
- 12名健康参与者进行了模拟布鲁克西斯运动 (BMwTC,BMwoTC,非BM).
- 记录了来自按摩器,下,下和下巴肌的EMG数据,以及相邻的声音数据.
- 采用单流和多流HMM进行分类,采用一个单流和多流的交叉验证方法.

Stereotypes, Prejudice, and Discrimination
95.4K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Automatic Processing and Automatic Social Behavior
242
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Understanding Consciousness
2.0K
Consciousness can be defined as the state of being aware of and able to think about one's existence, sensations, and surroundings. It encompasses two major components: awareness and arousal. Awareness pertains to the recognition of environmental stimuli and internal states. At the same time, arousal refers to the physiological readiness to engage with these stimuli, which varies significantly between states like sleep and wakefulness.

Machines
573
Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. One example of a machine is the cutting plier, which is used to cut wires by applying forces to its handles. When equal and opposite forces are exerted on the handles of the cutting plier, they cause the cutting edges to come together and apply equal and opposite reaction forces on the wire, which are greater than the applied forces.

Generalization, Discrimination, and Extinction
1.4K
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...
