因为Wide & Deep模型的训练和预测,运算还是比较多,比较费时,用在大规模物品的召回阶段,性能开销有点吃不消。 只有当召回层的数据,已经从几百万到几百以后,可以通过为Wide & Deep模型对召回的百级别的物品进行排序,得到前top N(N=20)。 七. 总结 Wide & Deep模型被用在了排序层。成wide和deep两部分。 * ...
Session用来执行Graph里规定的计算,就好像给一个个门电路通上电,我们在Session里,给计算单元冲上数据,That’s Flow. 重复计算单元反复训练800次,提高其准确度 为了快速查看训练效果,每轮训练只给10000个训练数据(subset),恩,每次都是相同的训练数据 将计算单元graph传给session 初始化参数 传给session优化器 - trai...
import oneflow as flow x = flow.tensor([-1.0, 2.0], device="cuda") y = flow.relu(x) print(y) 系统首先创建了一个在GPU上的输入Tensor,然后调用了导出到python端的c++ functional接口relu。这里涉及到pybind11绑定相关的Python wrapper和C++ relu functor。这个交互的上层,同事在OneFlow学习笔记:python到...

In this article, we observed the basics of Tensors and what do these do in a computational graph. The actual objective for creating this is to make Tensors flow through the graph. We write the tensors and through sessions we make them flow. ...
所谓Tensorflow,正是由Tensor(张量)+Flow(流动)两个英文单词组成的,TensorFlow 的计算图的每个节点的输入输出都是 Tensor,而连接节点的有向线段就是 Flow,表示从一个 Tensor 状态到另一个 Tensor 状态。在深度学习中,Tensor实际是一个多维数组,如果有足够的高等数学和线性代数的知识,就能够很好地理解这一点。它的...
