Models can be conceptual, graphical or mathematical as they are used in science. It allows one to break down a concept into simpler terms with a visual component. A limitation of models in science is that they are usually simplified versions of the real situation or concept.
A Temporal Investigation of Crash Severity Factors in Worker-Involved Work Zone Crashes: Random Parameters and Machine Learning Approaches:
Reason:
In the context of work zone safety, worker presence and its impact on crash severity has been less explored. Moreover, there is a lack of research on contributing factors by time-of-day. To accomplish this, first a mixed logit model was used to determine statistically significant crash severity contributing factors and their effects. Significant factors in both models included work-zone-specific characteristics and crash-specific characteristics, where environmental characteristics were only significant in the daytime model. In addition, results from parameter transferability test provided evidence that daytime and nighttime crashes need to be modeled separately. Further, to explore the nonlinear relationship between crash severity levels and time-of-day, as well as compare the effects of variables to that of the logit model and assess prediction performance, a Support Vector Machines (SVM)
What is meant by machine learning approach?
Machine Learning is an AI technique that teaches computers to learn from experience. Machine learning algorithms use computational methods to “learn” information directly from data without relying on a predetermined equation as a model.

Answer:
The answer is: The practice of foot binding represented the increasing subjugation of women during the Qing dynasty.
Explanation:
Although foot binding was viewed as an honorable act during the Qing dynasty, it has been viewed by scholars as a form of female subjugation because it made women incapable of dancing and moving around/about as much as they possible. Foot binding made it difficult for women to have healthy feet because women used long bandages to cover their feet, and they could only remove the bandages once after every 14 days. Generally, these incidences subjugated women by making them emotionally fragile, less effective and less mobile in society, and more dependent on the men who married them.
