  • Darts: classic network search method based on gradient descent, open end-to-end network search | ICLR 2019

    Time:2021-6-11

    Darts is a classic NAS method, which breaks the previous discrete network search mode and can carry out end-to-end network search. Because darts updates the network based on gradient, the direction of update is more accurate, and the search time is greatly improved compared with the previous method. Cifar-10 only needs 4gpu days.  Source: Xiaofei’s […]

  • Fbnet / fbnetv2 / fbnetv3: Facebook’s lightweight network exploration in NAS field | lightweight network

    Time:2021-6-7

    Fbnet series is a lightweight network series completely based on NAS method. The shortcomings of current search methods are analyzed and innovative improvements are gradually added. Fbnet combines DNAs and resource constraints, fbnetv2 adds channel and input resolution search, and fbnetv3 uses accuracy prediction for fast network structure search  Source: Xiaofei’s algorithm Engineering Notes official […]

  • Paper reading: u-net

    Time:2020-11-16

    introduction This paper introduces a U-shaped network structure for semantic segmentation. In fact, it is based on the idea of encoding and decoding, which can effectively combine the information of low resolution and high resolution, and can better segment the image edge. It was proposed in the same year as FCN, but u-net uses a […]

    introduction Pixel level classification tasks such as semantic segmentation have been developed a lot, and the existing models are developing towards higher and higher accuracy. However, such tasks also have important applications for embedded devices, so real-time semantic segmentation is essential. However, most of the models are towards high-precision, which is very poor in real-time. […]
