# Preserving Training Dynamics Across Batch Sizes in Machine Learning
In the world of practical machine learning, preserving training dynamics across different batch sizes is a crucial tool. This ability allows for a trade-off between batch size and wall-clock time, providing flexibility and efficiency in the training process. The key to this trade-off lies in a scaling rule, where adjustments are made to factors such as learning rate in order to accommodate varying batch sizes.
Additionally, another significant tool in the realm of machine learning is the model EMA (Exponential Moving Average). The model EMA serves as a functional copy of a target model, with its parameters gradually aligning with those of the target model based on an EMA at a momentum hyperparameter. This technique has been proven to enhance robustness and generalization in supervised learning, stabilize pseudo-labeling, and offer a learning signal for Self-Supervised Learning (SSL).
However, previous studies have overlooked the optimization of the model EMA when performing scaling, resulting in discrepancies in training dynamics across different batch sizes and ultimately reducing the model’s performance.
In a recent study, experts have introduced a scaling rule designed to optimize the model EMA’s performance across various architectures, optimizers, and data modalities. The results demonstrated the effectiveness of this rule in cases where the model EMA contributes to the target model’s optimization, enabling the training of EMA-based pseudo-labeling and SSL methods at both small and large batch sizes.
One notable achievement from this study is the successful training of BYOL (Bootstrap Your Own Latent) up to a staggering batch size of 24,576 without compromising performance, resulting in a remarkable 6× reduction in wall-clock time under idealized hardware settings.
This breakthrough in optimizing training dynamics across batch sizes marks a significant advancement in the field of machine learning, offering a more efficient and adaptable approach to model training across various scales. As the demand for scalable and robust machine learning solutions continues to grow, this development holds great promise for the future of the industry.
Conclusion:
In conclusion, preserving training dynamics across batch sizes in machine learning is crucial for balancing batch size and wall-clock time. The scaling rule, along with the model EMA, improves robustness, generalization, and provides a learning signal for SSL. This work provides a scaling rule for optimization with model EMA.
