In the ever-evolving landscape of AI, traditional training methods are struggling to keep pace. The growing complexity of models and the sheer volume of data demand a more efficient approach. This is where distributed training steps in, offering a revolutionary solution. This blog series will delve into the world of distributed training, exploring how it tackles these challenges and with platforms like @AIxBlock, it's becoming more accessible than ever.
Distributed training is a technique used in machine learning, specifically in training complex models with massive datasets. It tackles the challenge of handling these demanding workloads by splitting the training process across multiple machines or devices, significantly speeding things up.
Dividing the Workload: Imagine a large dataset to be fed into a complex model for training. In distributed training, this data gets divided into smaller chunks. These chunks are then distributed to multiple machines, often called worker nodes.
Parallelization: Each worker node gets a copy of the model and trains it on its assigned data chunk. This process happens in parallel, meaning all the worker nodes train the model simultaneously.
Communication and Updates: While each node trains independently, they need to communicate and share information to ensure the overall model progresses coherently. This communication typically involves exchanging gradients, which are essentially the direction for adjusting the model's parameters to improve its accuracy.
There are two broad approaches to distributed training:
Data parallelism: Here, each worker node has a complete copy of the model. They train the model on their assigned data chunk and then share the gradients. These gradients are then aggregated to update the parameters of the model on all the worker nodes.
Model parallelism: In this approach, instead of dividing the data, the model itself is divided and distributed across the worker nodes. Each node trains a different part of the model on the entire dataset. Then, the communication between nodes focuses on exchanging information to ensure the different model pieces work together effectively.
