Two languages which Pearl was meant to replace:

Perl was a combination of two languages “sh” and “awk” with more added features and hence it replaced these two languages.

“sh” was the first scripting language which contained a small set of commands. These commands were considered as system calls that performed file filtering or file management. Support for variables, control flow statements and functions made it a complete programming language.

“awk” was another scripting language which was initially used for generating reports but later became a general purpose language...

Note : please avoid using AI answer the question by carefully reading it and provide a clear and concise solutionHere is a clear background and explanation of the full method, including what each part is doing and why. Background & Motivation Missing values: Some input features (sensor channels) are missing for some samples due to sensor failure or corruption. Missing labels: Not all samples have a ground-truth RUL value. For example, data collected during normal operation is often unlabeled. Most traditional deep learning models require complete data and full labels. But in our case, both are incomplete. If we try to train a model directly, it will either fail to learn properly or discard valuable data. What We Are Doing: Overview We solve this using a Teacher–Student knowledge distillation framework: We train a Teacher model on a clean and complete dataset where both inputs and labels are available. We then use that Teacher to teach two separate Student models: Student A learns…
