    01 IFQ-Net: Integrated Fixed-point Quantization Networks for Embedded Vision (1911.08076)

     (for example XNOR-Net and HWGQNet, quantize the data into 1 or 2 bits)

    In this paper, we propose a fixed-point network
    for embedded vision tasks through converting the floatingpoint data in a quantization network into fixed-point. Furthermore, to overcome the data loss caused by the conversion, we propose to compose floating-point data operations
    across multiple layers (e.g. convolution, batch normalization and quantization layers) and convert them into fixedpoint.

    量化网络层 将浮点数据转换为固定点数据;

    为了减小数据丢失,转换过程跨多个层(卷积 正则化 量化);

    IFQ-Net, for embedded vision. It divides a quantization
    network into substructures and then converts each substructure into fixed-point in either separated or the proposed integrated manner.

    将网络分为不同的子结构,然后将每个子结构以分离的或集成方式转换为定点。

    first we divide a trained floating-point
    quantization network into substructures and then we convert
    each substructure into its fixed-point counterpart. We employ HWGQ-Net algorithm to train a floating-point quantization network

    02 DupNet: Towards Very Tiny Quantized CNN with Improved Accuracy for Face(1911.05341)

    Detection

    we propose DupNet which consists of two parts.
    Firstly, we employ weights with duplicated channels for the
    weight-intensive layers to reduce the model size. Secondly,
    for the quantization-sensitive layers whose quantization
    causes notable accuracy drop, we duplicate its input feature
    maps. It allows us to use more weights channels for convolving more representative outputs.

    1) it reduces the model size of a quantized network by duplicated weights for weight-intensive layers;

    2)it increases the accuracy through duplicating the input feature maps of its quantization-sensitive layers.

    1:权重密集层复制权重参数(使用同样的参数,减小模型尺寸)

    2:量化密集层复制输入特性映射(增加准确率)
