+Features
+
+Reasonably fast, without GPU:
+With TBB threading and SSE/AVX vectorization.
+98.8% accuracy on MNIST in 13 minutes training (@Core i7-3520M).
+Portable and header-only:
+Runs anywhere as long as you have a compiler which supports C++14.
+Just include tiny_dnn.h and write your model in C++. There is nothing to install.
+Easy to integrate with real applications:
+No output to stdout/stderr.
+A constant throughput (simple parallelization model, no garbage collection).
+Works without throwing an exception.
+Can import caffe's model.
+Simply implemented:
+A good library for learning neural networks.
