统一使用了640×360分辨率的图片进行对比参数量和FLOPS状态。 上表对BiSeNet网络和其他网络就MIOU和FPS上进行比较,可以看出该方法相比于其他方法在速度和精度方面有很大的优越性。 Parameters¶ class torch.nn.Parameter [source] ¶. A kind of Tensor that is to be considered a module parameter. Parameters are Tensor subclasses, that have a very special property when used with Module s - when they’re assigned as Module attributes they are automatically added to the list of its parameters, and will appear e.g. in parameters() iterator. 深度神经网络在人工智能的应用中,包括语音识别、计算机视觉、自然语言处理等各方面,在取得巨大成功的同时,这些深度神经网络需要巨大的计算开销和内存开销,严重阻碍了资源受限下的使用。本章总结了模型压缩、加速一般原理和方法,以及在移动端如何部署。 – Appropriate counting of FLOPs for complex instructions • div, exp, log and sin/cos should be counted as multiple FLOPs rather than 1 – Appropriate counting of FLOPs for predicated-out threads • FLOPs are only counted on non-predicated threads 21 Vary nwfrom 1 to 6 Tostudyimpact of varyingArithmeticIntensity on performance FLOP/s is better ime FLOPs per kernel)) 4x lower FLOP/s !!!

However, standard pooling operators reduce the feature size gradually to avoid significant loss in information via gross aggregation. Consequently, CNN architectures tend to be deep, computationally expensive and ... Java 编程语言的线程模型可能是此语言中最薄弱的部分.它完全不适合实际复杂程序的要求,而且也完全不是面向对象的.本文建议对 Java 语言进行重大修改和补充,以解决这些问题.

  • The pruning approaches also suffer from sharp accuracy drop if we increase the degree of FLOP pruning. Using proposed HetConv filters, we have state-of-art result regarding FLOPs compare to the FLOP pruning methods. Also, the pruning process is inefficient as it takes a lot of time in training and fine tuning after pruning.
  • For more details, see tf.nn.depthwise_conv2d. The batch_group_count (default value 1) argument can be used for grouped filters during backpropagation. batch_group_count needs to be a divisor of the size of the lhs (input) batch dimension.
「1x1畳み込みを使うと計算効率がよくなるよ」という話は聞いたことあっても、具体的にどれだけ良くなるのかを理論的に議論されることはあまり多くないように思います。自分の理解も含めて、一度これをちゃんと整理したいと思います。少し数式多めで...

DALI预处理加速. 增加对Nvidia DALI GPU数据预处理库的支持,可用于加速图片,视频,语音等数据预处理。 conv2d_fft This is a GPU-only version of nnet.conv2d that uses an FFT transform to perform the work. It flips the kernel just like conv2d. conv2d_fft should not be used directly as it does not provide a gradient. Instead, use nnet.conv2d and allow Theano’s graph optimizer to replace it by the FFT version by setting ‘THEANO_FLAGS=optimizer ...
