What are edge artificial intelligence and edge computing?
Edge artificial intelligence is one of the most noteworthy new areas in artificial intelligence. It is allowing people to run artificial intelligence processes without having to worry about privacy or data transmission. The speed slows down. Edge AI is making the use of artificial intelligence wider and more widespread, allowing smart devices to respond quickly to input without accessing the cloud. While this is a quick definition of edge AI, let’s take a moment to better understand edge AI by exploring some use cases. First, edge AI has widespread applications in the healthcare industry. For example, integrating edge AI on monitoring devices can more accurately monitor and analyze patients’ vital signs and respond immediately when needed. This capability can make healthcare more efficient while also reliably handling sensitive personal data. In addition, edge artificial intelligence can also be applied to smart homes. By integrating artificial intelligence into home devices, such as smart speakers and smart TVs, users can interact with smart devices more widely and conveniently. The existence of edge artificial intelligence makes these devices no longer need to rely on the cloud.
What is edge computing?
In order to truly understand edge artificial intelligence, we first need to understand edge computing and understand the most important aspects of edge computing. The best way is to compare it to cloud computing. Cloud computing is the provision of computing services over the Internet. In contrast, edge computing systems do not connect to the cloud but run on local devices. These local devices can be dedicated edge computing servers, local devices, or Internet of Things (IoT). There are many advantages to using edge computing. For example, Internet/cloud-based computing is limited by latency and bandwidth, while edge computing is not limited by these parameters.
What is edge artificial intelligence?
Now that we understand edge computing, we can look at edge artificial intelligence. Edge AI combines artificial intelligence and edge computing. Artificial intelligence algorithms run on devices with edge computing capabilities. The benefit of this is that the data can be processed in real time without the need to connect to the cloud.
Most cutting-edge artificial intelligence processes are performed in the cloud because they require large amounts of computing power. The result is that these AI processes are prone to downtime. Because edge AI systems run on edge computing devices, required data operations can be performed locally, sent when an Internet connection is established, and save time. Deep learning algorithms can run on the device itself (the point of origin of the data).
Edge AI is becoming increasingly important as more and more devices require AI without access to the cloud. Think about how many factory robots or cars are now equipped with computer vision algorithms. In this case, data transfer lag time can be fatal. Because fast response times are so important, the device itself must have an edge AI system that enables it to analyze and classify images without relying on a cloud connection.
When information processing tasks performed in the cloud are delegated to edge computers, the result is real-time latency, real-time processing. Furthermore, by limiting data transfer to the most important information, the data volume itself is reduced and communication interruptions are minimized.
Edge AI and IoT
Edge AI is combined with other digital technologies such as 5G and the Internet of Things (IoT). The IoT can generate data for use by edge AI systems, and 5G technology is critical to the continued development of edge AI and IoT.
The Internet of Things refers to various smart devices that are connected to each other through the Internet. All of these devices generate data that can be fed into an edge AI device, which also serves as a temporary storage unit for the data until synchronized with the cloud. This method of data processing allows for greater flexibility.
The fifth generation mobile network 5G is crucial to the development of edge computing intelligence and the Internet of Things. 5G can transmit data at higher speeds, up to 20Gbps, while 4G can only transmit data at 1Gbps. 5G also supports simultaneous connections (1,000,000 per square kilometer) supporting better latency speeds (1ms to 10ms). These advantages over 4G are important because as the Internet of Things develops, the amount of data will grow and transmission speeds will be affected. 5G enables more interactions between a wider range of devices, many of which can be equipped with edge computing intelligence.
USE CASES FOR EDGE AI
Use cases for edge AI include almost any situation where data processing can be done more efficiently on a local device than through the cloud. However, some of the most common use cases for edge AI include self-driving cars, autonomous drones, facial recognition, and digital assistants.
Self-driving cars are one of the most relevant use cases for edge artificial intelligence. Self-driving cars must constantly scan their surroundings and assess the situation, making corrections to their trajectory based on nearby events. Real-time data processing is critical for these situations, so its on-board edge artificial intelligence system is responsible for data storage, operation and analysis. Edge AI systems are necessary to bring Level 3 and 4 (fully autonomous) vehicles to market.
Because autonomous drones are not flown by human operators, their requirements for self-driving cars are very similar. If a drone loses control or malfunctions during flight, it could crash and cause damage to property or life. Drones may fly beyond the range of internet access points, and they must have edge AI capabilities. For services like Amazon Prime Air, which aims to deliver packages via drones, edge AI systems will be integral.
Another use case for edge AI is facial recognition systems. Facial recognition systems rely on computer vision algorithms to analyze data collected by cameras. Facial recognition applications used for tasks such as security need to run reliably even when not connected to the cloud.
Digital assistants are another common use case for edge AI. Digital assistants like Google Assistant, Alexa and Siri must be able to run on smartphones and other digital devices even when not connected to the internet. When data is processed on the device, it does not need to be transferred to the cloud, which helps reduce traffic and ensure privacy.

Context-augmented AI coding assistant using Rag and Sem-Rag
Jun 10, 2024 am 11:08 AM
Improve developer productivity, efficiency, and accuracy by incorporating retrieval-enhanced generation and semantic memory into AI coding assistants. Translated from EnhancingAICodingAssistantswithContextUsingRAGandSEM-RAG, author JanakiramMSV. While basic AI programming assistants are naturally helpful, they often fail to provide the most relevant and correct code suggestions because they rely on a general understanding of the software language and the most common patterns of writing software. The code generated by these coding assistants is suitable for solving the problems they are responsible for solving, but often does not conform to the coding standards, conventions and styles of the individual teams. This often results in suggestions that need to be modified or refined in order for the code to be accepted into the application

Can fine-tuning really allow LLM to learn new things: introducing new knowledge may make the model produce more hallucinations
Jun 11, 2024 pm 03:57 PM
Large Language Models (LLMs) are trained on huge text databases, where they acquire large amounts of real-world knowledge. This knowledge is embedded into their parameters and can then be used when needed. The knowledge of these models is "reified" at the end of training. At the end of pre-training, the model actually stops learning. Align or fine-tune the model to learn how to leverage this knowledge and respond more naturally to user questions. But sometimes model knowledge is not enough, and although the model can access external content through RAG, it is considered beneficial to adapt the model to new domains through fine-tuning. This fine-tuning is performed using input from human annotators or other LLM creations, where the model encounters additional real-world knowledge and integrates it
To provide a new scientific and complex question answering benchmark and evaluation system for large models, UNSW, Argonne, University of Chicago and other institutions jointly launched the SciQAG framework
Jul 25, 2024 am 06:42 AM
Editor |ScienceAI Question Answering (QA) data set plays a vital role in promoting natural language processing (NLP) research. High-quality QA data sets can not only be used to fine-tune models, but also effectively evaluate the capabilities of large language models (LLM), especially the ability to understand and reason about scientific knowledge. Although there are currently many scientific QA data sets covering medicine, chemistry, biology and other fields, these data sets still have some shortcomings. First, the data form is relatively simple, most of which are multiple-choice questions. They are easy to evaluate, but limit the model's answer selection range and cannot fully test the model's ability to answer scientific questions. In contrast, open-ended Q&A
SOTA performance, Xiamen multi-modal protein-ligand affinity prediction AI method, combines molecular surface information for the first time
Jul 17, 2024 pm 06:37 PM
Editor | KX In the field of drug research and development, accurately and effectively predicting the binding affinity of proteins and ligands is crucial for drug screening and optimization. However, current studies do not take into account the important role of molecular surface information in protein-ligand interactions. Based on this, researchers from Xiamen University proposed a novel multi-modal feature extraction (MFE) framework, which for the first time combines information on protein surface, 3D structure and sequence, and uses a cross-attention mechanism to compare different modalities. feature alignment. Experimental results demonstrate that this method achieves state-of-the-art performance in predicting protein-ligand binding affinities. Furthermore, ablation studies demonstrate the effectiveness and necessity of protein surface information and multimodal feature alignment within this framework. Related research begins with "S
