Edge AI, a term increasingly prominent in the realm of edge computing, combines the powers of Edge Computing and Artificial Intelligence (AI). Essentially, it involves running AI algorithms, or trained models, on edge computing infrastructure situated close to where data is generated and users are located. This proximity enables rapid data processing, often within milliseconds, facilitating real-time feedback—a crucial capability for various business domains.
The Fusion of Edge Computing and AI:
Edge AI merges Edge Computing and AI, allowing AI algorithms to operate near users and data sources for swift, real-time processing.
Key Characteristics of Edge AI:
- Provides real-time responses, essential for applications like personal safety, industrial automation, medical analysis, and retail.

So how does AI work?
Let us first define some definitions:
- Model: In the context of artificial intelligence, a model refers to a mathematical representation or formula that is designed to generate an output based on input data. This output could be predictions, classifications, decisions, or any other form of analysis depending on the specific task the model is built for. Models are constructed through a process called training, where they learn patterns and relationships within the data. They serve as the core component of AI systems, enabling them to perform tasks such as image recognition, language translation, and data analysis.
- Training: Training is the iterative process of refining and improving a model by exposing it to labeled data and adjusting its internal parameters accordingly. During training, the model learns to recognize patterns and make predictions based on the input data. This process typically involves feeding the model with a large dataset containing input-output pairs, where the correct output (label) is provided for each input. The model then adjusts its parameters through techniques like gradient descent to minimize the difference between its predictions and the actual labels. Training a model requires significant computational resources, especially for complex models or large datasets.
- Training data: Training data refers to the set of labeled examples used to train a model. These examples consist of input data along with corresponding output labels, which serve as the ground truth for the model to learn from. The quality and quantity of training data are crucial factors that influence the performance and accuracy of the trained model. High-quality training data should be representative of the real-world scenarios the model will encounter, and it should cover a diverse range of cases to ensure robustness. Generating good models often necessitates collecting and curating large volumes of training data to capture the complexities of the problem domain accurately.
- Inference: Inference is the process of using a trained model to make predictions or decisions on new, unseen data. Once a model has been trained, it can be deployed and used to analyze incoming data and generate outputs without further modification. Inference involves passing input data through the trained model and obtaining the corresponding output predictions. Unlike training, which can be computationally intensive and requires substantial resources, inference is typically less resource-intensive and can be performed quickly, making it suitable for real-time applications on the edge. Inference plays a crucial role in applying AI models to tasks such as image recognition, natural language processing, and autonomous decision-making.
The more training data that is available the better it is to fit the model and achieve good results. Often systems need to acquire and classify a lot of data before sufficient training can be done. Many more advanced models actually do continuous training on new data in order to improve the model going forward while in a field test or even in production. The newly trained model needs again to be deployed on the edge to achieve the detection through interference.
Conclusion
In conclusion, Edge AI offers a potent solution for addressing business challenges by harnessing the combined capabilities of edge computing and artificial intelligence, paving the way for enhanced efficiency, responsiveness, and innovation across various industries. Qbee plays a crucial part in continuously deploying the new model parameters to the edge devices to achieve an interference process with high accuracy.
