comprehensive guide to Key Frameworks and References in ML System Optimization 2024

The realm of Machine Learning (ML) Optimization has seen tremendous advancements with the rise of new frameworks and tools that make training models more efficient, secure, and scalable. As ML continues to grow in applications from healthcare to finance, these advancements play a vital role in ensuring that models are not only accurate but also computationally efficient. In this blog, we will delve into some of the most impactful ML frameworks, key notations used in federated learning (FL), and references that have shaped the field of ML system optimization.

Understanding the Role of Federated Learning (FL) in ML Optimization

Federated Learning (FL) is a decentralized machine learning method that enables multiple devices or clients to collaboratively learn a shared prediction model while keeping the data localized. It has emerged as a solution to privacy concerns while still leveraging the power of machine learning. In federated learning, data does not need to leave the client’s device, reducing the risk of exposure and improving security.

Federated Averaging (FedAvg) is the most commonly used algorithm in FL. The idea behind FedAvg is simple: the central server averages the locally computed updates from each client and sends back the aggregated result. This method is efficient in terms of communication and can work with non-IID (Independent and Identically Distributed) data as well.

Key Notations in Federated Learning

In ML optimization, especially in FL, several notations are used to represent various components of the model, clients, and data involved in the training process. Some key notations include:

• Ci: Data owner or client in the federated system.
• Di: The training data of client Ci.
• Li: Local learning model of client Ci.
• G: The global learning model, which is updated after training rounds.
• t: Denotes the round of learning.
• Gt: Parameters of the global model at the t-th round.

These notations form the basis of the algorithmic structure that FL and other distributed machine learning frameworks follow.
