Why request this? Is there some common wisdom here I’m missing? You should probably include the reason or else this just seems like a weirdly petty request

bwastion Machine learning benchmark: GPU providers

“IBM Softlayer and LeaderGPU appear expensive, mainly due to under-utilisation of their multi-GPU instances. The benchmark was carried out using the Keras framework whose multi-GPU implementation was surprisingly inefficient, at times performing worse than a single GPU run on the same machine.“ - this is unacceptable in a benchmark like this. There is an entire software stack that is influencing performance and much of the hardware is dissimilar.

bwastion Evidence that collaboration results in group-think and mediocrity

Where’s the evidence? Self reported happiness of intelligent people in those situations does not prove anything with regard to collaboration killing creativity. What if creativity tends to come with unhappiness?

bwastion Google translates German “halb zwei” to French “deux heures et demie”: 1h off

You may be spot on :)

“…a multilingual NMT model trained with Portuguese>English and English>Spanish examples can generate reasonable translation for Portuguese>Spanish although it has not seen any data for that language pair. We show that the quality of zero shot language pairs can easily be improved with little additional data of the language pair in question,” the paper states.

bwastion Bringing neural networks to cellphones

I doubt pruning alone is going to serve up the same kind of wins that energy aware architectures will. The main problem is that convolutions are heavy computational operations. There has been ongoing research in modifications to the convolution that basically decrease the amount of computation being done in channel space (grouped and depthwise separable convolutions). The tradeoff is accuracy, but new techniques (like shuffling the channels) are helping recover that.

MobileNets and ShuffleNet are some examples. They see 10x reductions in MACs, far more than the "73 percent reduction in power consumption over the standard implementation of neural networks" talked about in this article. https://arxiv.org/pdf/1704.04861.pdf https://arxiv.org/pdf/1707.01083.pdf

bwastion Chinese room argument

From the article, in "Replies":

The fact that man does not understand Chinese is irrelevant, because it is only the system as a whole that matters. Searle notes that (in this simple version of the reply) the "system" is nothing more than a collection of ordinary physical objects; it grants the power of understanding and consciousness to "the conjunction of that person and bits of paper" without making any effort to explain how this pile of objects has become a conscious, thinking being. Searle argues that no reasonable person should be satisfied with the reply, unless they are "under the grip of an ideology".

bwastion DeepLearning10: The 8x Nvidia GTX 1080 Ti GPU Monster

Do 1080tis have fp16 support? Seems like a waste if the model can be fp16 trained and you're using full 32bit.

Similarly you should probably try a bunch of other frameworks (caffe2, cntk, mxnet) as they might be better at handling this non standard configuration.
