Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Loess.jl is primarily developed for Julia, which may limit its accessibility and utility for developers who are not familiar with or do not use the Julia programming language.
Setting up Loess.jl requires a working knowledge of the Julia package manager (Pkg) and potentially additional dependencies, which can be challenging for beginners or those unfamiliar with Julia's ecosystem.
Local regression algorithms like Loess.jl can become computationally expensive when applied to very large datasets, leading to slow performance and increased memory usage.
