Federated learning: Unlocking the potential of secure,
distributed AI
In the rapidly advancing realm of Artificial Intelligence (AI), the sophistication of our daily digital
companions—ranging from spam filters to chatbots and personalized recommendation engines—is
fundamentally powered by data. These AI innovations have traditionally been fueled by centralized
repositories of vast data sets harvested online or donated by users.
However, a paradigm shift is underway within AI, steering towards a decentralized methodology that
harnesses the collective strength of distributed data. Federated learning stands at the forefront of this
shift, enabling AI models to be trained on the very devices that fill our pockets and homes—mobile
phones, laptops, and private servers. This approach ensures that personal data remains local, thereby
safeguarding privacy and adhering to strict regulatory standards on data management.
Federated learning is not just a response to privacy concerns; it explores the wealth of untapped data. It
processes information where it originates, leveraging the latent power of data streams from a multitude of
sources, such as satellites and urban infrastructure, to the myriad of smart devices that have become
integral to our domestic settings. Emergen Research reports that the federated learning market, valued at
USD 112.7 million in 2022, is expected to expand at a compound annual growth rate of 10.5% in the
coming years.
This article delves into the core of federated learning, examining its operational principles, its diverse
applications, and the significant benefits it offers.

What is federated learning?
Federated learning is a machine learning technique that enables multiple client devices to collaboratively
train a shared model without exchanging individual data with each other or a central server. This
approach allows training to occur locally on client devices, upholding the principles of data
decentralization and privacy.
The essence of federated learning lies in harnessing the collective knowledge from distributed datasets
across client devices rather than aggregating data in a single repository. This methodology not only
addresses data privacy and security concerns but also circumvents the challenges associated with
transferring large volumes of sensitive data to a central server.
By enabling models to be trained directly on client devices, federated learning takes advantage of diverse
datasets reflective of various real-world scenarios and user behaviors. Such diversity bolsters the model’s
ability to generalize across different conditions, enhancing its robustness and predictive performance.
Federated learning fosters a form of collective intelligence through its collaborative training process.
Local models on client devices contribute to refining the global model, facilitating a shared learning
experience while preserving the privacy of each client’s data.
This technique is invaluable in contexts where privacy is paramount, including healthcare and any
domain dealing with sensitive user information. Federated learning thus represents an optimal trade-off,
maximizing the utility of shared learning experiences while safeguarding individual data sovereignty and
privacy.
How does federated learning work?
Federated learning aims to train a unified model using data from multiple sources without the need to
exchange the data itself. Below is a streamlined explanation of the federated learning process:
Initialization of a baseline model by a central server: The process begins with a central server
initializing a baseline model. This initial model embodies a generic set of knowledge, serving as the
foundational framework.
The participation of devices (nodes or clients): The devices, like smartphones or computers, each
containing their own data, participate as nodes or clients. These clients prioritize privacy and choose not

3/15
to share their data.
Local training: Each client device independently trains the baseline model using its unique local data.
For instance, a smartphone may utilize data from user interactions like photos or text messages to
enhance the model’s knowledge, thus personalizing it based on individual usage.
Model updates: After local training, the client devices send their updated model parameters or weights
back to the central server. These updated parameters capture the knowledge gained from training on the
local data.
Secure aggregation: The central server uses secure aggregation techniques to combine and average
the model updates received from multiple client devices. This process ensures that the privacy of the
individual data sources is maintained. By aggregating the updates, the central model gains insights from
diverse sources of data.
Iterative improvement of the central model: The central server then incorporates the aggregated
updates into the central model, making it more refined and knowledgeable. The model learns from the
collective intelligence of all the client devices.
Model distribution: The updated central model is then shared again with the client devices. The client
devices receive the improved model, which captures the combined knowledge from the entire federated
learning process.
Iterative process: The cycle of local training, model parameter updates, aggregation, and model
distribution is repeated over multiple rounds. With each iteration, the models on the client devices
become more personalized, and the central model becomes more generalized and accurate. The
process continues, benefiting from collective intelligence while preserving privacy.
Federated learning enables collaborative model training across multiple devices while keeping the data
decentralized and protecting user privacy. It allows for personalized models on individual devices and a
central model that captures collective knowledge without sharing raw data.

How can we enhance data privacy in federated learning through
advanced security techniques?
The main advantage of federated learning is that organizations can leverage the power of AI without
compromising the privacy and security of sensitive data. Keeping data within their secure premises
significantly reduces the risk of data breaches or unauthorized access.
Privacy in federated learning can be classified into two aspects:
Local privacy
It protects the privacy of local data at an individual level by sharing model updates instead of raw data.
Global privacy
It ensures that the model updates made during each round remain private and inaccessible to third
parties, except for the central server.
Various techniques are employed for privacy in federated learning; they are:
Differential privacy: Differential privacy is a critical technique in federated learning, where
individual devices or clients train models on their local data without sharing the raw data. To ensure
privacy, differential privacy can be applied by introducing random noise to the model updates
before they are shared with the central server. This prevents the re-identification of specific data
points and provides privacy for participants. By incorporating differential privacy in federated
learning, organizations can strike a balance between data privacy and model accuracy.

5/15
Homomorphic encryption: Homomorphic encryption enables secure computation on encrypted
data. In the context of federated learning, homomorphic encryption allows data to remain encrypted
while being processed by local devices. This means that the central server can perform operations
on the encrypted model updates without decrypting the underlying data. By utilizing homomorphic
encryption, federated learning can ensure end-to-end data privacy, as the sensitive information
remains protected even during the model aggregation process.
Secure Multiparty Computation (SMC): It plays a crucial role in preserving privacy in federated
learning. By utilizing SMC, numerous devices or clients can work together to train a shared model
without revealing their individual data to one another or the central server. This approach ensures
that computations are distributed, enabling each client to contribute its model updates securely.
SMC effectively prevents the disclosure of sensitive information and upholds the privacy of
individual data throughout the federated learning cycle.
Differential privacy, homomorphic encryption, and secure multiparty computation can be employed in
conjunction with federated learning to strengthen privacy preservation at various stages of the learning
process. By leveraging these techniques, federated learning enhances privacy and security, allowing
organizations to collaboratively train models on decentralized data without compromising the
confidentiality of the underlying information.
Types of federated learning
Federated learning encompasses two fundamental types: Model-centric and Data-centric. Model-centric
federated learning is currently more prevalent and widely adopted. Let’s delve into this approach to gain a
deeper understanding.
Model-centric federated learning
Model-centric federated learning prioritizes the development and enhancement of the machine learning
model across decentralized data sources. It involves iterative experimentation to determine the most
effective model architecture and training algorithms.
In this approach, the emphasis is on refining the model’s code or architecture to boost its performance
rather than altering the underlying data. The core goal is to advance the model’s capabilities through
codebase enhancements, ensuring that the model can learn effectively from the distributed and varied
datasets in a federated learning network.
We will now explore the methodologies and practices that define model-centric federated learning:
Cross-device federated learning
Cross-device federated learning is a privacy-centric machine learning approach that enables a multitude
of devices to collaboratively enhance a shared model while keeping their raw data private, not sharing it
with a central server or amongst themselves. This method integrates the principles of federated learning
with the ability to perform distributed training across a diverse array of devices.
Unlike traditional setups, where a central server dispatches model updates to devices that then use their
local data to compute and return updates, cross-device federated learning maintains a central server for

6/15
coordination but does not require direct data exchange between devices. The primary aim is to harness
the rich diversity of data across devices to refine the model’s effectiveness.
Each device contributes by training on its own data and sharing model updates, which are then
aggregated by the central server. Through this process, a more comprehensive and generalized model
emerges, benefitting from the collective insights gathered across the various participating devices.
Horizontal federated learning
Horizontal federated learning, also known as sample-based federated learning or homogenous federated
learning, is particularly suitable when datasets share the same feature space but differ in samples. In this
case, the data is horizontally split, meaning each participating device or entity has rows of data with
consistent features but potentially different samples.
Horizontal federated learning is where multiple entities or organizations collaborate to train a shared
model while keeping their data local. Unlike vertical federated learning, which involves different entities
holding different types of data that can be combined to build a more comprehensive model, horizontal
federated learning focuses on scenarios where the entities hold similar types of data.
In horizontal federated learning, the participating entities typically have their own local datasets, which
may be similar in terms of features or data types. These entities collaboratively train a shared model by
exchanging model updates while keeping their data decentralized and private.
Vertical federated learning
Vertical federated learning is a type of federated learning where multiple entities or organizations
collaborate to train a shared model by combining different types of data that are vertically partitioned
across the entities. Unlike horizontal federated learning, which focuses on similar types of data with
consistent features, vertical federated learning involves different entities holding complementary and non-
overlapping data attributes or features.
In vertical federated learning, the data from different entities are divided based on their specific attributes
or features. Each entity holds a unique subset of attributes, and by combining these subsets, a more
comprehensive model can be trained. The model updates are computed locally on each entity’s data, and
only the updates, rather than the raw data, are exchanged among the entities.
Cross-silo federated learning
Cross-silo federated learning is a variant of federated learning involving collaboration between multiple
organizations or entities, each with its own separate data silo. In this context, a data silo refers to a
storage system or repository where data is isolated and accessible only to a specific organization or
entity.
Cross-silo federated learning aims to train a shared model by leveraging the data available in each
organization’s silo without directly sharing or centralizing the data. Each organization retains control over
its own data, ensuring privacy and security.

7/15
Federated transfer learning
Federated transfer learning represents an intriguing area of research that combines the benefits of
transfer learning and federated learning techniques. Transfer learning has demonstrated its effectiveness
in leveraging knowledge acquired from one supervised learning task to improve performance on a related
task.
In conventional transfer learning, a common approach involves fine-tuning a pre-trained network by
removing the last few layers and retraining it on a smaller dataset to recognize specific labels. In contrast,
federated transfer learning involves additional steps that are more complex. These steps often include
intermediate learning processes that aim to map the data from distributed entities to a shared feature
subspace. This mapping facilitates knowledge transfer and collaborative model training, ensuring that
privacy is maintained while leveraging diverse data sources.
Data-centric federated learning
Data-centric federated learning is a developing approach that extends traditional federated learning
principles to emphasize data ownership, privacy, and secure access. This approach resembles a peer-to-
peer model where data owners grant external entities the capability to build models using their data
without actually transferring the data.
The philosophy behind data-centric federated learning is not limited to merely providing access to private
data. It envisages a network where private, siloed data could be accessible to various organizations,
fostering the creation of machine-learning models for a broad spectrum of applications.
Under this paradigm, data owners maintain their data in a secure environment, enabling external data
scientists to conduct training or inference on this remotely hosted data. Unlike model-centric approaches
that typically rely on pre-existing models, data-centric federated learning focuses on extracting value from
the data itself.
Realizing the full promise of data-centric federated learning necessitates tools for efficient data discovery,
wrangling, and preparation within the network, ensuring readiness for model training and inference while
upholding privacy. Furthermore, employing protective measures such as differential privacy and private
set intersection (PSI) is crucial for preventing data exposure, thus supporting data governance and
compliance.
Navigating the complexities of automated control and meeting the diverse requirements of data handling,
privacy, and compliance presents significant challenges in data-centric federated learning. Integrating
automated processes with privacy-enhancing technologies like differential privacy and PSI will be critical
in realizing the potential of this approach, all while maintaining stringent data security and regulatory
compliance.
Algorithms used in federated learning
Federated learning encompasses several algorithms that enable collaborative training of machine
learning models in a decentralized manner. Some of the commonly used federated learning algorithms
include:

8/15
Federated Stochastic Gradient Descent (FedSGD)
In traditional stochastic gradient descent (SGD), the computation of gradients is based on mini-batches,
which are subsets of data samples drawn from the entire dataset. In the context of federated learning,
these mini-batches can be viewed as individual client devices, each having access to its own local data.
With Federated Stochastic Gradient Descent (FedSGD), the central model is initially distributed to all
participating clients. Each client independently computes the gradients using its local data, reflecting the
model’s performance on its specific dataset. These client-specific gradients are then transmitted back to
the central server.
At the central server, the gradients received from each client are aggregated, considering the proportion
of data samples each client represents. This aggregation process ensures that clients with larger
datasets contribute more significantly to calculating the gradient descent step. By considering the relative
sizes of the local datasets, the central server appropriately weighs the gradients from different clients
during the aggregation process.
The resulting aggregated gradient updates the central model, reflecting the collective knowledge and
insights gained from the distributed clients. This iterative process of distributing the model, computing
gradients locally, and aggregating them at the central server continues for multiple rounds, progressively
refining the global model based on the diverse datasets held by the clients.
FedSGD enables collaborative training while respecting data privacy and security. It allows clients to
contribute knowledge without transmitting raw data to the central server. By leveraging the distributed
nature of client devices, FedSGD enables efficient and privacy-preserving model updates in the federated
learning setting.
Federated Averaging (FedAvg)
FedAvg is an extension of the FedSGD algorithm that introduces the concept of aggregating client model
weights instead of gradients. In FedAvg, clients have the flexibility to perform multiple local gradient
descent updates before sharing their model weights with the central server. This allows clients to fine-
tune their local models based on their specific datasets and computation resources.
Unlike FedSGD, where clients transmit gradients to the central server, FedAvg focuses on exchanging
model weights. Instead of directly sharing gradients, clients send their updated model parameters
(weights) to the central server. This shift from gradients to weights enables more flexibility in the training
process.
The central server aggregates the received model weights from the clients, typically by taking the
weighted average of the models based on the size of each client’s local dataset. By averaging the client’s
data weights, the central server obtains a refined global model that incorporates the knowledge
contributed by each client.
The key advantage of FedAvg is that it allows clients to perform multiple local updates and fine-tune their
models before sharing the results with the central server. This flexibility enables clients to take advantage
of their local data and computational resources, potentially improving the quality of the shared global

9/15
model. Moreover, if all clients start from the same initial model, averaging the gradients is equivalent to
averaging the weights, allowing for efficient aggregation and convergence.
FedAvg is a powerful technique in federated learning as it strikes a balance between client-specific fine-
tuning and collaborative model improvement. By combining local updates and global aggregation,
FedAvg enables the collective intelligence of distributed clients to contribute to the creation of an
accurate and robust global model.
Federated Learning with Dynamic Regularization (FedDyn)
Regularization is a fundamental technique in traditional machine learning that enhances model
performance by introducing a penalty term to the loss function, encouraging model simplicity and
reducing overfitting. In the federated learning context, where disparate devices train a shared model on
their own data, integrating local losses into a cohesive global loss presents a unique challenge.
FedDyn offers a solution by implementing dynamic regularization. Instead of applying a static
regularization term, FedDyn dynamically adjusts the regularization based on the local updates from each
device. This dynamic adjustment ensures that local models stay closely aligned with the global model
despite the inherent differences in local data distributions.
The innovation of FedDyn lies in mitigating the discrepancies between local model updates and the
global objective. By customizing the regularization term for each device’s updates, FedDyn guides local
models to minimize global loss collectively and more effectively. This approach facilitates a more
cohesive and efficient federated learning process, yielding improved model performance across the
network.
Benefits of federated learning
The benefits of federated learning include:
Privacy preservation: Federated learning prioritizes data privacy by keeping user data on local devices.
Instead of sending raw data to a central server, model updates are shared, ensuring that sensitive
information remains secure and confidential. This decentralized approach helps address privacy
concerns and regulatory requirements.
Data security: Federated learning minimizes the need for data transfer, limiting exposure to potential
security vulnerabilities during transmission or storage. Since data remains on local devices, the risk of
data breaches or unauthorized access is significantly reduced.
Efficient resource utilization: Clients participate in model training using their own devices, eliminating
the necessity for extensive data transfers and minimizing computational and communication costs. By
leveraging local computing resources, federated learning reduces the need for massive centralized
infrastructure.
Collaborative learning: Federated learning enables devices like mobile phones to train a shared
prediction model collectively. This collaborative approach keeps training data on the device itself,

10/15
eliminating the need for data uploads to a central server. It fosters a sense of cooperation and knowledge
sharing while maintaining data privacy.
Time efficiency: Organizations can collaborate to address challenges in machine learning models more
efficiently. For instance, highly regulated sectors like hospitals can collaboratively train life-saving models
while upholding patient privacy, accelerating the development process. With federated learning, there is
no need to repeatedly invest time in collecting and aggregating data from diverse sources.
How to do text generation using federated learning?
In this section, we will leverage TensorFlow Federated (TFF) to implement federated learning on a pre-
trained text generation model. The model, initially trained on Charles Dickens’s novels, will be fine-tuned
using federated learning specifically for Shakespeare’s works. We’ll load the pre-trained model, generate
text using it, and then proceed with the federated learning process to adapt the model to Shakespearean
language patterns. Let’s embark on this journey to explore the fascinating intersection of deep learning
and federated learning in natural language processing.

Load a pre-trained model
Load a pre-trained model that was trained using the TensorFlow tutorial on text generation with a
Recurrent Neural Network (RNN) and eager execution (Eager execution allows operations to be
executed immediately as they are called, providing a more imperative and interactive interface similar to
other deep learning frameworks like PyTorch or NumPy). However, instead of training it on the complete
works of Shakespeare, we pre-trained the model using the text from Charles Dickens’s novels,
specifically “A Tale of Two Cities” and “A Christmas Carol.”
This initial model may not be state-of-the-art, but it produces reasonable predictions and is sufficient for
the purposes of this tutorial. The final model was saved using the
