FEDERATED LEARNING : Your data stays with you

#artificialintelligence

For example when you grant access of your location information to any application, it collects your location data. Now it's upon the application how they want their AI algorithm to use it. Both have their own advantages and disadvantages. Training on the server needs huge amount of storage to store the data and a world-class security to safeguard them from data breaches. Whereas on-device training is trained on limited amount of data and the model performance is compromised.


Federated Learning: An Introduction - KDnuggets

Advancements in the power of machine learning have brought with them major data privacy concerns. This is especially true when it comes to training machine learning models with data obtained from the interaction of users with devices such as smartphones. So the big question is, how do we train and improve these on-device machine learning models without sharing personally-identifiable data? That is the question that we'll seek to answer in this look at a technique known as federated learning. The traditional process for training a machine learning model involves uploading data to a server and using that to train models.

Smart doorbells have been playing an important role in protecting Furthermore, the processing and storage of multiple video streams our modern homes. Existing approaches of sending video streams make the subscription more costly. Secondly, this design requires to a centralized server (or Cloud) for video analytics have been a huge amount of reliable bandwidth, which may not always be facing many challenges such as latency, bandwidth cost and more had. Third, even if we assume that we could address latency and importantly users' privacy concerns. To address these challenges, bandwidth issue by empowering a sophisticated infrastructure, a this paper showcases the ability of an intelligent smart doorbell large class of video-based applications may not be suitable because based on Federated Deep Learning, which can deploy and manage of regulations and security concerns of sharing data as there is an video analytics applications such as a smart doorbell across Edge involvement of biometric data of residents.


Federated Learning: A Decentralized Form of Machine Learning

#artificialintelligence

Most major consumer tech companies that are focused on AI and machine learning now use federated learning – a form of machine learning that trains algorithms on devices distributed across a network, without the need for data to leave each device. Given the increasing awareness of privacy issues, federated learning could become the preferred method of machine learning for use cases that use sensitive data (such as location, financial, or health data). Machine learning algorithms and the data sets that they are trained on are usually centralized. The data is brought from edge devices (mobile phones, tablets, laptops, and industrial IoT devices) to a centralized server, where machine learning algorithms crunch it to gain insight. However, researchers have found that a central server doesn't need to be in the loop.


The Tradeoff Between Privacy and Accuracy in Anomaly Detection Using Federated XGBoost

arXiv.org Machine Learning

Privacy has raised considerable concerns recently, especially with the advent of information explosion and numerous data mining techniques to explore the information inside large volumes of data. In this context, a new distributed learning paradigm termed federated learning becomes prominent recently to tackle the privacy issues in distributed learning, where only learning models will be transmitted from the distributed nodes to servers without revealing users' own data and hence protecting the privacy of users. In this paper, we propose a horizontal federated XGBoost algorithm to solve the federated anomaly detection problem, where the anomaly detection aims to identify abnormalities from extremely unbalanced datasets and can be considered as a special classification problem. Our proposed federated XGBoost algorithm incorporates data aggregation and sparse federated update processes to balance the tradeoff between privacy and learning performance. In particular, we introduce the virtual data sample by aggregating a group of users' data together at a single distributed node. We compute parameters based on these virtual data samples in the local nodes and aggregate the learning model in the central server. In the learning model upgrading process, we focus more on the wrongly classified data before in the virtual sample and hence to generate sparse learning model parameters. By carefully controlling the size of these groups of samples, we can achieve a tradeoff between privacy and learning performance. Our experimental results show the effectiveness of our proposed scheme by comparing with existing state-of-the-arts.
