概括
人工智能 (AI) 在解释心肌梗塞 (MI) 的心声回声图方面表现有前途,但目前的视觉解释可能会阻碍,而不是帮助临床医生的表现. 未来的人工智能集成需要与临床推理一致的解释.
科学领域:
- 心脏病学 心脏病学
- 人工智能的人工智能
- 医疗成像医学成像
背景情况:
- 声心谱对于评估心肌梗塞 (MI) 是至关重要的,但受到观察者变化的影响.
- 人工智能 (AI) 提供了自动解释的潜力,但它对人类-AI合作的影响需要研究.
研究的目的:
- 评估人工智能驱动的解释对心脏病学实习生的诊断绩效的影响,这些实习生解释心脏病发作心脏回声图.
主要方法:
- 一个ResNet18-LSTM模型被训练来从心声图视频中检测心脏病发作.
- 梯度加权类激活映射 (Grad-CAM) 产生了视觉解释.
- 心脏病学学员的诊断表现在三个条件下进行了比较:仅仅是回声片段,与AI预测,以及AI预测加上Grad-CAM解释.
主要成果:
- 人工智能模型实现了高分辨性性能 (AUC 0.92500.9429).
- 单独使用人工智能 (80.0%准确率) 略高于单独使用临床医生 (77.0%).
- 将人工智能与人类判断相结合并没有提高性能;视觉解释将准确度降低到72%,特异性降低到83.8%.
结论:
- 人工智能可以在心声回声图中检测出心脏病发作,但目前的解释性方法可能与临床推理不一致.
- 可解释的AI技术可能会损害诊断性能,如果与临床工作流程不一致.
- 未来的人工智能集成需要解释策略来补充,而不是阻碍临床医生的专业知识.

Improving Translational Accuracy
14.9K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Uncertainty in Measurement: Accuracy and Precision
100.8K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
