The table clearly illustrates the combined benefits of noise-aware filtering and carbon budgeting, offering superior robustness and sustainability for Federated Learning deployments.
Federated Learning's decentralized nature makes it ideal for leveraging distributed renewable energy sources. However, the challenge of unknown data quality at client devices can severely impede training efficiency and model performance. This research provides a novel solution.

This systematic approach ensures that only clients contributing positively to model convergence are selected, leading to more stable and efficient federated training.
Data quality is a hidden challenge in privacy-preserving Federated Learning. The inability to directly inspect client data necessitates robust mechanisms to identify and mitigate noisy or corrupted samples without compromising privacy.
Experimental Setup for Carbon-Aware FL with Noise Simulation
Our evaluation used a realistic setup to demonstrate the effectiveness of noise-aware and carbon-budgeted FL:
- Dataset: CIFAR-10 (non-IID, Dirichlet α=10) distributed across 30 clients.
- Model: A simple Convolutional Neural Network (CNN) with 2 convolutional and 3 fully connected layers.
- Training Parameters: 10 clients selected per round, 2 local epochs, batch size 32, Adam optimizer (learning rate 0.001).
- Noise Simulation: 6 clients had their data corrupted by adding zero-mean Gaussian noise (σ=1) to images, simulating real-world imperfections.
- Carbon Data: Hourly carbon intensity historical data from US energy regions (Electricity Maps) was assigned to each client.
This comprehensive setup allowed for rigorous testing of our proposed gradient norm thresholding and carbon budget allocation strategies under challenging conditions.
The results confirm that blindly selecting clients based on high loss, a common strategy, can inadvertently select noisy data, degrading model performance. Our noise-aware approach directly addresses this.
Optimizing deep learning training for both performance and resource efficiency is a continuous challenge. This research leverages insights from critical learning periods and gradient norm statistics to make client selection smarter and more robust, especially in distributed environments.
By focusing on identifying high-impact data and filtering out detrimental noise, the training process becomes more stable, converges faster, and achieves higher final accuracy, even with resource constraints like carbon budgets.
The use of gradient norms as a proxy for data quality, inspired by the Fisher Information Matrix, represents an efficient way to infer data utility without privacy breaches, paving the way for more intelligent optimization techniques in Federated Learning.
