Média Federada

Média Federada (FedAvg) é uma abordagem inovadora no campo de aprendizado descentralizado aprendizado de máquina, designed to train models across multiple devices while preserving privacidade de dados. It allows for aprendizado colaborativo without needing to share raw data, making it particularly useful in scenarios where data is sensitive or distributed, such as in healthcare or finance.

A ideia central por trás do Média Federada é realizar atualizações locais treinamento de modelos on individual devices. Each device, or client, trains a model on its local dataset for a set number of iterations. Once the local training is completed, each device uploads only the model updates (weights and biases) to a central server, rather than the actual data. The server then aggregates these updates, typically by calculating a weighted average based on the number of data points each device used. This aggregated model is then sent back to the clients for further training.

This process can repeat multiple times, with the model gradually improving as more rounds of training and aggregation occur. By using Federated Averaging, organizations can leverage the power of distributed data while ensuring compliance with data privacy regulations, as the sensitive data never leaves the individual devices.

In summary, Federated Averaging is a powerful technique that enables collaborative model training across many devices, enhancing privacy and security enquanto ainda alcança resultados de aprendizado de máquina de alta qualidade.
