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。 * ...
Currently, the Tensor Types we’ve been dealing with have no type safety on the dimensions. Tensor Flow doesn’t provide this information when interacting with the C library. So it’s impossible to enforce it at a low level. But this doesn’t stop us from writing wrappers that allow us ...
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...

第二,Google在白皮书上展望了TensorFlow是一个分布式系统上的机器学习框架。但是从目前Tensor Flow的release来看,他们只支持单机多卡,不支持多机的分布式环境。就深度学习这个具体方向上,目前public available的不支持分布式的DL库已经有10个以上,Google当前发布TF作为一个general-purpose的产品,定位有待进一步观察; ...

As our tensors flow through our networks, certain shapes are expected at different points inside the network, and as neural network programmers, it is our job to understand the incoming shape and have the ability to reshape as needed.
