Abstract. This paper presents FAS-CT a novel approach to a distributed low-latency Deep Learning inference system based on a Field Programmable Gate Array (FPGA). The system incorporates continuous training capabilities based on Concept Drift Detection, where each model prediction is compared with the ground truth to detect a change in the data patterns that the model requires to adapt to. FAS-CT is formed by two main execution pipelines. First, is the Inference pipeline powered with Xilinx® Zynq® UltraScale+™ MPSoC FPGA and where low latency is the target. Second, is the Retraining pipeline its objective is to adapt the model as soon as possible when Concept Drift is detected. A complete characterization of FAS-CT is provided in this article using a neural network model and an experimental setup. The latency of the Prediction pipeline achieved was 5.79 ms. The total degradation of the model when continuous training is activated is 57\% in contrast to when is deactivated which is 1609\%. These results demonstrate that FAS-CT is suited for real-time Deep Learning inference and can be automatically adapted to evolving data environments.
