    DLPF: A Parallel Deep Learning Programming Framework Based on Heterogeneous Architecture

    • Deep learning plays an important role in machine learning field, and it has been widely used in various applications. The prospect of research and applications of deep learning are huge. However, deep learning also faces several challenges. Firstly, there are many tools in deep learning field, but these tools are not convenient to use for non-expert users because the installation and usage of them are really complex. Secondly, the diversity of deep learning is limited because the flexibility of existing deep learning models is not enough. Furthermore, the training time of deep learning is so long that the optimal hyper-parameters combination cannot be found in a short time. To solve these problems, we design a deep learning programming framework based on heterogeneous architecture in this paper. The programming framework establishes a unified module library which can be used to build a deep model through the visual interface conveniently. Besides, the framework also accelerates the basic modules on heterogeneous platform, and makes the speed of searching optimal hyper-parameters combination be faster. Experimental results show that the programming framework can construct deep models flexibly, and more importantly, it can achieve comparative classification results and better timing performance for a variety of applications. In addition, the framework can search optimal hyper-parameters efficiently and make us infer the relationship of all hyper-parameters.
