Wireless sensing is a fancy term that involves collecting data about people's actions or health without needing wires—like magic! Over the years, this technology has improved a lot, making it possible to recognize actions, measure vital signs, and estimate poses. Imagine having a device that knows if you're falling while you're on a business trip, all because of wireless sensing. How cool is that?

The Shift to Big-Time Use

After years of development, wireless sensing is finally ready to jump from labs into real-world applications. Companies are creating devices that use technologies like Wi-Fi and radar to keep track of what people are doing. You've probably heard of some big names working on this tech—think Google’s special chips for gesture recognition and many startups entering the market.

What is CCS?

Now, let’s introduce CCS, which stands for Continuous Customized Service. CCS is all about making sure that wireless sensing can adapt to what users need over time. If you're on a vacation but want to keep an eye on your elderly relatives, CCS helps bring that service right to you without sending sensitive data over the internet. It’s like having a remote control for your sensing needs!

The Problem of Forgetting

When trying to add new features, many systems face a problem called "catastrophic forgetting." This is a fancy way of saying that when you learn something new, you can easily forget what you already knew. Imagine learning to ride a bike and then forgetting how to walk! CCS tackles this challenge by ensuring that as new services are added, the old ones don’t get thrown out the window. This is crucial for scenarios where you love new features but still want to keep the old ones handy.

How Does CCS Work?

CCS operates in three main stages to keep things organized:

  1. Base Model Service: This is the starting point where providers share a basic sensing model with users.
  2. Incremental Model Service: Users can request new features, and the system updates their model accordingly.
  3. Continuously Incremental Model Service: This is where the magic happens. The system keeps evolving to meet new needs without losing any old abilities.

Keeping Data Safe

One of the coolest things about CCS is that it doesn’t need to send your private data to service providers. Instead, users can keep their data on their own devices, making it hard for others to access it. So, if you want to detect falls for loved ones while you’re sipping cocktails on a beach, CCS has got your back!

The Importance of Data

To ensure CCS works smoothly, users provide data relevant to their new needs while the system retains old data. This helps create a balance so that users can enjoy new features without missing out on existing capabilities. Think of it as swapping out an old battery for a new one while keeping your flashlight shining bright!

Assessing Performance

To see how effective CCS is, extensive experiments were conducted using a dataset called XRF55, which contains a variety of actions and scenarios. The results showed that CCS not only performs well in recognizing new actions but also does a great job of remembering old ones. So, whether you’re doing a dance move or just walking to the fridge, CCS has figured it out!

A Little Comparison

When compared to other methods, CCS stood out as a champion in keeping the balance between old and new services. While other methods tended to forget previous tasks after learning new ones, CCS cleverly avoided that pitfall.

How CCS Chooses Data Wisely

One of the secrets to CCS’s success is how it chooses exemplars, which are samples of past data used to teach the model. By selecting important data points, CCS can ensure that the model remembers critical actions while adjusting to meet new needs. It’s like having the perfect playlist that includes your favorite old songs while still allowing new hits to join in!

Learning From Others

CCS also uses a concept known as Knowledge Distillation. This technique takes what the model has learned and teaches it to a new one, allowing the new model to retain all the important information. It’s akin to passing down family recipes from one generation to the next—so your grandma's secret cookies never go out of style.

Balancing Act

Another aspect of CCS is weight aligning, which ensures that the model doesn’t get overwhelmed by new demands. Just like balancing a plate of food, it focuses on keeping everything evenly distributed. Too much of one thing can lead to disaster, and CCS knows that all too well!

Real-World Applications

The potential applications for CCS are vast. From automating smart homes to creating advanced health monitoring systems, the sky's the limit. Imagine having a system that can adjust to your daily routines, alerting you when something seems off or assisting your loved ones when they need help.

Keeping Up With User Needs

As the system learns from users, it can adapt to their preferences and needs. For example, if a user starts cooking a lot of new dishes, CCS can adjust to track kitchen activities, ensuring safety and efficiency.

The Results Don’t Lie

After thorough testing using the XRF55 dataset, CCS demonstrated impressive accuracy and value. Users were delighted to discover that CCS not only recognized new action categories but also maintained a strong performance for previously learned tasks.

Putting CCS to the Test

The results showed that users experienced consistent improvements in performance across various stages. Whether it was through actions recognized in RFID, Wi-Fi, or millimeter-wave radar modalities, CCS didn’t disappoint.

Conclusion

In conclusion, CCS represents a significant step toward a flexible and responsive wireless sensing service. By meeting user needs while ensuring privacy and retaining vital knowledge, CCS opens doors to endless possibilities.

Imagine a world where your devices not only know what you need but also anticipate it. That’s the future CCS is paving. As technology continues to evolve, systems like CCS will play a crucial role in ensuring that the transition from old to new is as smooth as possible.

So, buckle up, folks! We are heading into a world where machines may just become our most attentive assistants—helpful, reliable, and always learning!

Title: CCS: Continuous Learning for Customized Incremental Wireless Sensing Services

Abstract: Wireless sensing has made significant progress in tasks ranging from action recognition, vital sign estimation, pose estimation, etc. After over a decade of work, wireless sensing currently stands at the tipping point transitioning from proof-of-concept systems to the large-scale deployment. We envision a future service scenario where wireless sensing service providers distribute sensing models to users. During usage, users might request new sensing capabilities. For example, if someone is away from home on a business trip or vacation for an extended period, they may want a new sensing capability that can detect falls in elderly parents or grandparents and promptly alert them. In this paper, we propose CCS (continuous customized service), enabling model updates on users' local computing resources without data transmission to the service providers. To address the issue of catastrophic forgetting in model updates where updating model parameters to implement new capabilities leads to the loss of existing capabilities we design knowledge distillation and weight alignment modules. These modules enable the sensing model to acquire new capabilities while retaining the existing ones. We conducted extensive experiments on the large-scale XRF55 dataset across Wi-Fi, millimeter-wave radar, and RFID modalities to simulate scenarios where four users sequentially introduced new customized demands. The results affirm that CCS excels in continuous model services across all the above wireless modalities, significantly outperforming existing approaches like OneFi.
