Time for a fact update!  My, my, how time flies.<p><i>Deep learning has really only recently become successful</i><p>hinton coined the term &quot;deep learning&quot; around 2006&#x2F;2007 (more around deep belief nets&#x2F;RBMs, but still, same thing), if that&#x27;s considered &quot;recently.&quot;<p><i>constrastive divergence and convolutional neural networks.</i><p>CD was also ~10 years ago.  CNNs were reading your checks and postal zipcodes in the mid 90s.<p><i>successfully train the network.</i><p>In the early 90s, RNNs were driving cars on highways using only webcams under basically VFR.  No giant sensors, no LIDAR, no GPS, no mesh networks, just camera input.
