What is Localized Computing?

Localized computing, a foundational principle of Edge AI, refers to the process of executing computational tasks directly on a local device instead of relying on a centralized, often cloud-based, system. This approach offers multiple benefits, including reduced latency, minimized bandwidth usage, enhanced data privacy, and less dependence on constant internet connectivity. Localized computing is crucial in environments that require real-time decision-making and where network availability is sporadic or unreliable.

Model Optimization Techniques in Edge AI

a) Quantization

Quantization is a technique used to reduce the numerical precision of an AI model’s parameters, thereby reducing the model's memory requirements and computational needs. This is crucial for deploying models on edge devices with limited resources, and while it may lead to a slight reduction in model accuracy, the trade-off is often acceptable for the benefits gained in efficiency.

b) Pruning

Pruning involves the elimination of certain parts of neural networks that contribute little to the model’s performance, such as weights close to zero. This results in a smaller and more efficient model, suitable for deployment on resource-constrained edge devices.

c) Knowledge Distillation

Knowledge distillation is a process where a smaller model (student) is trained to replicate the performance of a larger, more complex model (teacher). This technique is especially useful in Edge AI, allowing the development of lightweight models that retain a high level of accuracy.

Federated Learning: A New Learning Paradigm

Federated learning is an innovative approach to machine learning where a model is trained across multiple decentralized devices or servers holding local data samples and is not exchanged.
