Focusing on low$-$resource languages:

a$)$ Identify and analyze existing loss functions that can effectively capture the unique grammatical structures of low$-$resource languages, particularly those that differ significantly from high$-$resource languages.

b$)$ Select one of these loss functions and propose modifications to it$.$ Your modified loss function should: $($i$)$ Encourage the model to maintain performance on general language tasks

$($ii$)$ Simultaneously adapt to a low$-$resource language or specialized domain

Explain the reasoning behind your proposed modifications that satisfy the above constraints.
