Is Overlapping Training Data Impacting Your Student ML Results?

Finding a validation set that isn't fully independent of your training data can feel like a quiet flaw in an otherwise solid experiment. For a student project, it's a meaningful issue, but it doesn't have to sink the whole effort. The comparisons between experimental conditions remain useful because you applied the same evaluation procedure across the board. What suffers is the absolute performance numbers, not the relative differences.

Explore how distance shapes radar classification and what it means for your models

A model that scores higher every time range is added should raise an eyebrow, even when validation looks clean. The concern here is legitimate: radar returns fewer points from distant objects, so the model may be latching onto distance as a proxy for size or class. Stress testing means breaking the data so range distributions differ between training and validation sets. That reveals whether the model generalizes or memorizes the environment. Dropping the feature entirely is also worth exploring if the performance gap remains acceptable.

From scattered Word tables to a single, structured Excel file

Sixty Word files, each holding a similarly formatted table, sounds like a manual data-entry trap. You are right to avoid the copy-paste grind, especially since the language column refuses to stay put in a single cell. Splitting that overflow into individual rows is the real prize here. A formula-based approach is clever, but it is fragile and hard to hand off.
