UTD24是美国德克萨斯大学达拉斯分校(University of Texas at Dallas)的Naveen Jindal管理学院创建的一个数据库,用于追踪24种管理学期刊上发表的论文。以下是UTD24所追踪的24种管理学期刊123:
In conclusion, resilience is a dynamic and learnable trait that empowers individuals to face life’s difficulties with strength and courage. Cultivating resilience contributes not only to personal well-being but also to the overall resilience of communities and societies.
In summary, adaptability is a vital skill that empowers individuals to navigate the complexities of an ever-changing world. By fostering adaptability, individuals can not only cope with change but also thrive and lead others through periods of uncertainty.
Autonomy refers to the ability and freedom of individuals or entities to make independent decisions, take actions, and govern themselves without external control or interference. It is a fundamental concept in various contexts, including personal autonomy, organizational autonomy, and autonomy in artificial intelligence. Here are key aspects and implications of autonomy:
In summary, autonomy is a multifaceted concept that influences individual lives, organizational dynamics, and technological advancements. Striving for a balanced approach that respects autonomy while considering ethical, legal, and cultural factors is essential for fostering healthy and productive environments.
Iterative process:
K-means: Updates the cluster centers by iteratively calculating the distance from data points to the nearest cluster center.
SOM: Iteratively adjusts the weights of neurons through competitive learning and neighborhood adjustment.
Sensitivity to initial values:
K-means: Sensitive to the choice of initial clustering centers, different initial values may lead to different results.
SOM: Relatively less sensitive to the choice of initial weights, but the initial network topology needs to be chosen carefully.
Interpretability:
K-means: results are more intuitive, with each cluster represented by a center point.
SOM: Provides a topology of the data that can be used to visualize and understand high dimensional data.[label][/label][checkbox checked=”true/false”][/checkbox]
Topology:
K-means: K-means does not consider topological relationships between data points and focuses only on the location of cluster centers.
SOM: SOM considers the topological relationship between data points on a grid of neurons, preserving the spatial information between neighboring neurons.
Applicable scenarios:
K-means: Suitable for spherical, equal-sized clusters with similar density.
SOM: Suitable for capturing topological structures and nonlinear relationships in data, especially for visualization of high-dimensional data.
