Convolutional Neural Networks (ConvNets) enable computers to excel on vision learning tasks such as image classification, object detection. Recently, real-time inference on live data is becoming more and more important. From a system perspective, it requires fast inference on each single, incoming data item (e.g. 1 image). Two main-stream distributed model serving paradigms – data parallelism and model parallelism – are not necessarily desirable here, because we cannot further split a single input data piece via data parallelism, and model parallelism introduces huge communication overhead. To achieve live data inference with low latency, we propose sensAI, a novel and generic approach that decouples a CNN model into disconnected subnets, each is responsible for predicting certain class(es). We call this new more…
