Is 2024 the year of the Federated Learning ie "Year of Mobile ML"?

It is no secret that the increasing focus on data privacy and security, along with advancements in mobile technology, makes federated learning an attractive proposition. This approach allows mobile devices to contribute to machine learning models without sharing raw data, thus preserving user privacy. The growing computational power of mobile devices enables them to handle the local processing required for federated learning, making this more feasible than in the past. Before we continue, let's solidify the lexicon.

What is Federated Learning?

Federated Learning is a machine learning approach that enables the training of algorithms across multiple decentralized devices or servers holding local data samples, without exchanging them. This method is particularly beneficial for preserving privacy and reducing the need to transfer large amounts of data. In federated learning, an algorithm is sent to each device, where it learns from the data present there. The device then sends back only the updated model parameters, not the data itself, to a central server. The server aggregates these updates from all devices to improve the overall model. This process iteratively continues, resulting in a robust and comprehensive model trained on diverse data sources, while significantly mitigating privacy and security concerns.

But there is more...

Additionally, major tech companies are investing in federated learning research and implementation, which could accelerate its adoption. However, there are challenges, including managing the variability in hardware capabilities across devices, ensuring efficient use of battery and computational resources, and developing robust algorithms that can learn effectively from decentralized data. If these challenges can be addressed effectively in the near future, federated learning could indeed become a significant trend in mobile technology in 2024, offering a new paradigm for privacy-conscious, decentralized machine learning.

How Gesture ML will play a pivotal role for on-device processing in 2024?

Gesture-based Machine Learning (ML) and Large Language Models (LLMs) like GPT-4 are increasingly being used for analyzing and predicting various aspects of human behavior and intent.

Here are five examples of how these models can be utilized, according to GPT-4:

1. Emotion Recognition through Gestures: Gesture ML models can be trained on datasets of human gestures to predict emotional states. For example, a model might analyze the speed, rhythm, and amplitude of hand movements to infer whether a person is excited, nervous, or calm. This can be particularly useful in enhancing user experience in virtual reality or in providing emotional insights for mental health assessments.
2. Intent Prediction in Human-Computer Interaction: LLMs and ML models can interpret human gestures in the context of human-computer interaction. For instance, a model could analyze hand movements or facial expressions to predict a user's intent to select, move, or interact with virtual objects in a computer interface. This technology is increasingly relevant in the development of more intuitive and interactive VR and AR environments.
3. Gesture-Based Control in Robotics: Robotics can employ gesture ML models to understand and respond to human gestures. For example, a robot in a manufacturing setting might be trained to recognize specific hand signals from a human supervisor to start, stop, or change functions. This improves safety and efficiency in environments where traditional forms of communication may be impractical.
4. Health Monitoring and Rehabilitation: Gesture recognition models can play a significant role in health monitoring and physical rehabilitation. For instance, a model could analyze the movement patterns of a stroke patient to assess the progress of their recovery, or detect early signs of motor function decline in elderly patients, aiding in proactive healthcare.
5. Demographic Inference: While more ethically and technically complex, some ML models attempt to infer demographics like age, gender, or ethnicity based on physical gestures and speech patterns. However, it's crucial to note that such applications must be approached with extreme caution to avoid biases and respect privacy and ethical considerations.

These examples highlight the potential of Gesture ML and LLMs in various fields. However, it's important to remember that the accuracy and appropriateness of these technologies depend on the quality of the data they're trained on, and they must be developed and used with a strong commitment to ethical standards and privacy.

As of 11th of January 2024, it's challenging to definitively predict whether full 2024 will be the year that federated learning becomes prevalent on native mobile devices, but the trend is certainly moving in that direction.
