Accelerating Performance with the Artificial Intelligence of Things computer vision on radiographs, CT scans and MRIs to identify nodules and other areas of concern on the human brain and liver. This detection process uses deep learning techniques such as convolutional neural networks (CNN) to analyze visual imagery. necessary. For monitoring, diagnosing and acting on individual pieces of equipment, such as home automation systems, it makes sense to do the analysis as close to the device as possible. Sending locally sourced, locally consumed data to a faraway data center causes needless network traffic, delayed decisions and drain on battery powered devices. The clinic then uses a completely different AI technology – natural language processing – to build a patient profile based on family medical history, medications, prior illnesses and diet; it can even account for IoT data, such as pacemaker data. Combining natural language data with computer vision, the tool enables valuable medical staff to be much more efficient. With the exponential increase in IoT devices and their data volumes – along with demand for low latency – we have seen a trend to move analytics from traditional data centers toward devices on the edge – the “things” – or to other compute resources close to edge and cloud – to the fog. Much of the value of the AI-empowered IoT is the promise to act now. Make customers the right offer before they look away. Detect the suspicious transaction before it is approved. Help that self-driving car maneuver through the busy intersection without crashing into other moving vehicles. Do it now. Latency matters. A concept just a few years old, fog computing shifts data processing, real-time analytics, security and networking functions from a centralized cloud to network nodes and gateways closer to the IoT devices or services. Fog computing or “fogging” enables the data to be processed locally. Only the results, exceptions or alerts are sent to a centralized data center. Faster results, less bandwidth. Clearly, many types of sensors and devices cannot wait for data or commands from the cloud. And for other uses, it just isn’t - 45 - June 2019
