what is deep learningcomplex and powerful models this also makes deep learning applicable to fairly small datasets deep learning has only been in the spotlight for few yearsand we haven' yet established the full scope of what it can do with every passing monthwe learn about new use cases and engineering improvements that lift previous limitations following scientific revolutionprogress generally follows sigmoid curveit starts with period of fast progresswhich gradually stabilizes as researchers hit hard limitationsand then further improvements become incremental deep learning in seems to be in the first half of that sigmoidwith much more progress to come in the next few years licensed to
