## Follow-up exercise
### Problem Statement
Now that you have implemented dynamic augmentation:
Extend your implementation further:
- Introduce conditional logic where every fourth epoch applies color jittering but only when training accuracy surpasses a certain threshold (e.g., greater than previous best).
- Modify your custom `RandomErasing` so that it erases multiple regions within an image rather than one region.
- Adapt your weighting mechanism so it dynamically adjusts sampling probabilities after every batch rather than once per epoch based on class distribution observed within each batch.

*** Excerpt ***
*** Revision 0 ***
## Plan
To create an advanced reading comprehension exercise that necessitates profound understanding along with additional factual knowledge beyond what is provided directly within the excerpt itself:
- We will incorporate complex scientific theories or historical events requiring prior knowledge or research skills beyond general awareness.
- We'll introduce advanced vocabulary relevant specifically to those fields alongside more general academic language.
- The excerpt will contain logical deductions that hinge upon understanding nuanced differences between similar concepts or theories.
- Nested counterfactuals (hypothetical "what ifs") will be employed alongside conditionals ("if...then" statements), requiring readers not only to follow complex logical sequences but also understand how altering one element might change outcomes across scenarios described.
By doing so, we aim at crafting content demanding both high-level language comprehension skills and specific factual knowledge outside common general education curricula.
## Rewritten Excerpt
In an alternate reality where Mendel had focused his genetic inquiries not upon peas but upon maize—a crop pivotal not merely agriculturally but also culturally across Mesoamerica—the trajectory of genetics might have diverged significantly from our own timeline’s path post-Mendel’s laws discovery circa mid-nineteenth century Europe.
Suppose Mendel had discerned principles analogous yet distinct due primarily to maize’s tetraploid genome complexity compared to pea plants’ diploid simplicity; he might have posited early hypotheses regarding gene linkage more akin to what Morgan would later articulate through Drosophila studies nearly six decades henceforth—albeit perhaps obscured by maize’s intricate chromosomal architecture rendering initial patterns less immediately discernible without modern cytogenetic tools.
Imagine further that this theoretical Mendelian framework had catalyzed advancements enabling pre-Wrightian synthesis—integrating quantitative genetics far sooner—potentially precipitating an earlier onset of evolutionary synthesis itself; this presupposes not merely technological advancement paralleling intellectual foresight but also sociopolitical climates conducive across disparate global locales fostering interdisciplinary exchange unfettered by prevailing Eurocentric scientific paradigms dominating late nineteenth-century thought landscapes.
## Suggested Exercise
In an alternate reality scenario where Gregor Mendel conducted his foundational experiments on maize instead of pea plants due largely because maize possesses a tetraploid genome compared to peas' diploid genome structure:
A) How might Mendel’s early hypothetical propositions regarding gene linkage contrast with those later articulated through Thomas Hunt Morgan’s Drosophila studies?
- I) They would likely be identical since both organisms exhibit clear genetic patterns irrespective of ploidy levels.
- II) They would possibly be more convoluted initially due to maize's complex chromosomal architecture obscuring patterns without contemporary cytogenetic tools yet still hint at gene linkage concepts akin those Morgan identified later.
- III) They would diverge completely since tetraploidy introduces entirely novel genetic mechanisms absent in diploid organisms like Drosophila melanogaster.
- IV) They would remain rudimentary hypotheses lacking substantive theoretical framework until post-Morgan era advancements rendered them testable through improved experimental methodologies.
