Does this mean ETC is compromised too?

Unless you want to execute the structure on multiple GPUs.

In neural translation seq2seq, using while_loop in the decoder RNN saves a lot of GPU time because it can quit early when a sentence ends.

Using tf.scan is a bad idea.

scan implements strict semantics so it will always execute the same number of timesteps no matter what the accumulator is (nan).

while_loop implements dynamic execution (quit once cond is not met) and at the same time allows parallel execution when some ops are not dependent on accumulator.

If you read the code for `dynamic_rnn` and contrib.legacy Seq2seq model you'll find while_loop. I have yet to see tensorflow library code using tf.scan anywhere!

Also, internally, scan is defined using while_loop. In my code, I find scan lacking in RNN and always have to fall back to while_loop.

Here is video of a talk by the RNN/Seq2Seq author himself:

I read the article and seems to be well-written though lacking.

For even more customized RNNs such as attention mechanism, beam search as in Seq2Seq, you'll need to skip the tf.dynamic_rnn abstraction and use a symbolic loop directly: tf.while_loop

He was against people calling Deep Blue AI when it was not. I doubt he would say the same thing about AlphaGo.
This is one of the many unconstructive comments
Thanks for the heads up. This will be free and open source. Also checkout my main project txtpen thanks.
It's been fixed. It was broken because it was querying a sub comment(not root comment).

MVP is minimum measurable product. When you have analytics set up, you are ready to launch. (mailing list)

You should talk the users and iterate your product. When you have enough traction, talk to investors. It'll make your life and theirs easier.

Hi. I set up a site called https://www.totalitarian.info

It's an invite only anonymous link aggregator

Or you can just write a small script that syncs Google Tasks to trello
