machine learning at the edge

You’ve probably heard about how machine learning and artificial intelligence are transforming the world. The hype around AI and ML seems to be everywhere. But for most of us, it still feels like science fiction. We struggle to understand how machine learning works and impacts our daily lives.

The good news is that machine learning is being used in practical ways at the edge – in devices we interact with every day.

In this post, we’ll explore real examples of machine learning at the edge that you may not even realize you’re already using. We’ll demystify how ML works on small devices to enable things like facial recognition, natural language processing, and object detection.

You’ll gain an understanding of how ML makes technologies like smart speakers, security cameras, and self-driving cars possible. Machine learning at the edge is here; it’s working behind the scenes, and it’s ready for you to take advantage of in your own products and services.

What Is Machine Learning at the Edge?

Machine learning at the edge refers to machine learning models that can run locally on edge devices like mobile phones, smart speakers, and IoT sensors. Instead of sending all your data to the cloud for processing, edge ML allows you to do initial processing right on your device.

Real-world use cases of machine learning at the edge:

Self-driving cars use edge ML to detect traffic lights, read signs, and avoid collisions without needing to connect to the cloud. Smart speakers employ on-device ML to detect wake words and understand voice commands even when the internet is down. – Security cameras can use edge ML for facial recognition, motion detection and object tracking instead of streaming all footage to the cloud.

Running ML models locally provides some key benefits:

  • Reduced latency. Not having to send data to the cloud and wait for a response means edge ML can provide real-time results.
  • Improved privacy. Sensitive data never leaves your device.
  • Less bandwidth is needed. Only relevant data or alerts are transmitted instead of raw sensor data.
  • Continued functionality without connectivity. Edge ML allows devices to continue working even when offline or in remote locations with poor connectivity.

While edge ML may have some limitations in model size and complexity, its ability to provide intelligent functionality without relying on cloud connectivity makes it an important and growing area of ML with many practical applications in the real world. The future is at the edge!

Real-World Examples of Machine Learning at the Edge:

Machine learning at the edge means using ML models on edge devices like smartphones, sensors, and IoT gadgets instead of sending all your data to the cloud. This allows for faster response times, better privacy, and less bandwidth usage. Here are a few real-world examples of ML at the edge in action:

1. Smart Home Assistants:

Virtual assistants like Alexa and Google Assistant use ML to understand speech and respond appropriately. By running some ML locally on Echo and Home devices, they can respond faster without needing the cloud for every query.

2. Autonomous Vehicles:

Self-driving cars rely heavily on ML to perceive the environment, determine the correct path, and control the vehicle. Running ML models on the car itself reduces latency and ensures critical functions like emergency braking work even without connectivity.

3. Security Cameras:

Smart security cameras can use ML to detect people, vehicles and other objects in video feeds. Performing this analysis on the camera instead of uploading all footage to the cloud improves privacy, reduces bandwidth needs, and allows for quicker alerts.

4. Wearable Fitness Trackers:

Fitness trackers use ML to track workouts, count steps, measure heart rate and more. Keeping ML on the device provides more detailed and personalized metrics without needing an internet connection and ensures sensitive health data stays private.

The future is at the edge. By utilizing ML locally on devices, we can build faster, smarter, and more private systems without relying so heavily on cloud computing and massive data centers. The examples above are just the beginning – ML at the edge will transform how we interact with technology in the years to come.

Implementing Machine Learning at the Edge: Key Considerations:

When implementing machine learning at the edge, there are a few key things to keep in mind.
First, you need to determine if edge ML is right for your use case. Edge ML works best for applications where latency and bandwidth are limited, and data privacy is important.

Some examples are predictive maintenance, computer vision, and natural language processing. If fast response times and data security aren’t major concerns, cloud ML may be a better option.
Second, choose a framework that suits your needs. Options like TensorFlow Lite, ONNX, and PyTorch Mobile are designed for edge deployment.

Compare factors like model optimization, platform support, and programming language to pick the right one.

Third, optimize your ML model for the edge. Use techniques like quantization, pruning, and layer fusion to reduce model size while maintaining accuracy.

The smaller and more efficient your model is, the better it will perform on edge hardware.
Finally, choose edge hardware that provides enough computing power for your model. Options range from microcontrollers like Arduino all the way up to embedded systems from NVIDIA, Intel, and Xilinx. More powerful hardware will allow for larger, more complex models.

These key considerations will put you well on your way to deploying machine learning models at the edge. The outcome is low-latency, data efficient AI which actually offers value to your end users.


And there you have it, some actual examples of machine learning models that can already run on edge devices today. Though all the excitement centers on cloud-based machine learning, edge ML is making terrific progress and offers some really exciting applications. Models and tools are getting more powerful, hardware is faster and smaller, and connectivity is better.

All of this adds up to edge ML moving into the mainstream. On-device ML is destined for a great future, too–driverless cars and smart homes will both require it; intelligent IoT must have it.

For engineering and product leaders, this is the time to start thinking about how you can use edge ML at scale across your entire organization now. The tools and examples are there – go out and build something amazing.
