Top 5 Frameworks to Supercharge Your Distributed Machine Learning Workflows
Distributed machine learning (DML) is revolutionizing how we approach data processing and model training. With massive datasets becoming the norm, leveraging distributed frameworks is crucial to optimize memory and compute resources, accelerate workflows, and minimize costs. In this post, we’ll explore the top five frameworks that can help you achieve these goals, ensuring your machine learning projects are scalable and efficient.
Why Distributed Machine Learning?
Before diving into the frameworks, let’s understand the significance of distributed machine learning. As datasets grow larger and more complex, processing them on a single machine becomes impractical. Distributed machine learning allows you to train models across multiple machines—whether using CPUs, GPUs, or TPUs—significantly reducing training time. These frameworks also enable data processing, model tuning, and serving using distributed resources, making them indispensable tools for modern data scientists.
