  Implementation of Face recognition system over Spark, with Tensorflow Face recognition accomplished by a Deep Learning method Convolutional neural network (CNN). The model was formed using a range of big-data frameworks. In this context, the main infrastructure is an Amazon cluster (AWS) over which Apacheʼs Hadoop and Spark were implemented. It used TensorflowOnSpark for conducting machine learning and deep neural networks. The system was fed with Face snapshots with Spark Streaming and after data pretreatment trained or classified. In the course of the experimental study, we focused on the performance of Tensorflow over Spark. Show less
