A recent survey of neural network optimization techniques from 2025-2026 reveals a significant expansion beyond simple Adam variants. The field now explores optimizers that operate on matrices and layers, adapt to dynamic training horizons, and manage state representations for sharded and low-precision computation. While matrix-aware methods show promise, the survey concludes that AdamW remains a robust choice, with rankings of optimizers varying based on model scale, data-to-parameter ratio, and other factors. This suggests a compositional approach to optimizer design and a need for stricter evaluation protocols. AI
IMPACT Suggests a more complex, compositional approach to designing and evaluating neural network optimizers, moving beyond simple variants.
