Anxiety: Overview

300
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

Generalized Anxiety Disorder

155
Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

Social Anxiety Disorder01:28

Social Anxiety Disorder

50
Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.

Treatment Strategies for Psychological Disorders01:24

Treatment Strategies for Psychological Disorders

169
Treatment approaches for psychological disorders fall into three main categories: psychological, biological, and sociocultural. Each approach targets different aspects of mental health, requiring varying levels of education and training.
Psychological therapies focus on modifying emotions, thoughts, and behaviors through talking, interpreting, listening, rewarding, challenging, and modeling. Clinical psychologists, counselors, and social workers commonly practice psychotherapy. Clinical...

科学领域:

  • 计算精神病学是一种计算精神病学.
  • 机器学习在医疗保健中的应用
  • 数据科学用于心理健康的数据科学.

背景情况:

  • 机器学习 (ML) 为分析复杂的临床数据提供了强大的工具,有助于诊断,治疗和预测结果.
  • 焦虑障碍的分析是一个重大挑战,因为患者数据的多维性和异质性而复杂化.
  • 在医疗保健中,越来越多的多视图数据 (MVD) 需要先进的方法来进行有效的处理和分析.

研究的目的:

  • 为焦虑数据引入一种新的预处理特征选择 (FS) 方法,称为多视图哈里斯霍克优化 (MHHO).
  • 为了减少焦虑MVD的维度,从而减少分析复杂性和提高处理效率.
  • 通过有效处理数据异质性,提高ML模型在分析焦虑障碍方面的准确性和可靠性.

主要方法:

  • 通过将多视图链接方法与哈里斯霍克优化 (HHO) 算法集成,开发了MHHO.
  • 利用多视图链接来创建一个适应性函数,该函数解释了不同数据视图中的异质性.
  • 雇佣HHO从MVD中识别出最佳的低维特征子集,由开发的健身功能指导.

主要成果:

  • MHHO展示了快速的融合,通常在十次代内,显著超过了最近的十个竞争对手的方法.
  • 该方法实现了大量的数据减少,删除了75%的视图,并将功能大小减少了66%.
  • 实现了接近100%的分类准确性,统计分析证实了其在竞争对手上的显著优势.

结论:

  • MHHO是一种高度有效和高效的特征选择方法,用于焦虑MVD.
  • 拟议的方法显著提高了分类准确性,并减少了精神障碍分析中的计算负载.
  • 进一步的研究可以探索已识别的诱发焦虑的特征及其与抑郁症和压力等并发性疾病的相关性.
