Anyone know of any benchmarks on tensorflow that provide a baseline estimate of the expected performance for some off-the-shelf hardware(s)?

These are the benchmarks supported by Soumith Chintala (Facebook AI Research):

They place TensorFlow performance on par with Torch (within 10%).

I find it so aggravating that nearly every last ML framework documents their CNN libraries in terms of canned MNIST datasets imported from the library in a preprocessed form. It's always left as a useless exercise for the reader to divine how to generate such a dataset from his/her own data. Examples should be way more general. The starting point shouldn't be: from tensorflow.examples.tutorials.mnist import input_dat…

Larger problem: mnist, images, and speech are probably low hanging fruits with rich features, large datasets, balanced datasets, etc. for which off the shelf packages work very well today.

Data cleaning is always a problem in statistics, so much so that most data scientists say that most of their time is spent on it.

The format for the dataset is here: http://yann.lecun.com/exdb/mnist/ A good exercise would be to figure out how to extract the data and put it into a numpy array. Then you can test on most - if not all - of the frameworks.

I recently parsed that in C#. It's simple enough to do, but the format is weird. It would be much simpler if the digits were stored as individual raw files in folders corresponding to each label.

I'm totally new to TensorFlow and ML in general, but I've been curious about how this could fit into a system.

Say you need a CNN text classifier algorithm to categorize simple single page documents. So you set one up via TensorFlow, train it with a big dataset, and get it outputting categories with decent accuracy. Could you then use some type of API and query it from a (low traffic) production web app?

Or is it more for the research phase rather than real-time interaction?

Does someone point me in the right direction for using a neural network for prediction (the input will be time series data). All the beginner's tutorials I have seen deal with classification and not prediction.

Thank you!
