dataset

问题 I checked the doc but I could not find a method for it. I want to de cross validation, so I kind of need it. Note that I'm not asking how to split a tensor, as I know that TensorFlow provides an API for that an has been answered in another question. I'm asking on how to partition a tf.Dataset (which is an abstraction). 回答1: You could either: 1) Use the shard transformation partition the dataset into multiple "shards".

问题 For background see my question here. So the problem now isn't that I can't send a DataSet to classic ASP but that it can't do anything with it. So I found some code to create a recordset xml structure from a DataSet . I have tweaked it a little from it's original source.

I have a variable x, which lists all the element names. I've already tried lots of things but nothing seems to work. The help for dataset() is also not helpful in this case. Hopefully somebody can help me with this final obstacle before I may finally see some results. 回答1: If I understand correctly, you have 50 variables in

问题 This question is an extension of the excellent answer provided by Robert Picard here: How to Randomly Assign to Groups of Different Sizes We have this dataset, which is the same as in the previous question, but adds the year variable: sysuse census, clear keep state region pop order state pop region decode region, gen(reg) replace reg="NCntrl" if reg=="N Cntrl" drop region gen year=20 replace year=30 if _n>15 replace year=40 if _n>35 If I just wanted to re-randomly assign reg 's across all

问题 I am using Crystal Report with VS 10, I have added DataSet.

问题 In KDD99 data set, a huge number of connections 32nd and 33rd feature’s value is greater than 100. I can’t understand the reason why used a connection window of 100 connections can get a value which is greater than 100? I consulted a lot of information, but found nothing. 回答1: The dataset contains 41 features for each connection. These features were obtained preprocessing TCP dump files. To do so, packet information in the TCP dump file was summarized into connections. Specifically (http:/
