The Quest to Build an Artificial Brain

Deep learning has suddenly spread across the commercial tech world, from Google to Microsoft to Baidu to Twitter, just a few years after most AI researchers openly scoffed at it.

All of these tech companies are now exploring a particular type of deep learning called convolutional neural networks, aiming to build web services that can do things like automatically understand natural language and recognize images. At Google, “convnets” power the voice recognition system available on Android phones. At China’s Baidu, they drive a new visual search engine.

But this is just a start. The deep learning community are working to improve the technology. Today’s most widely used convolutional neural nets rely almost exclusively on supervised learning. Basically, that means that if you want it to learn how to identify a particular object, you have to label more than a few examples. Yet unsupervised learning—or learning from unlabeled data—is closer to how real brains learn, and some deep learning research is exploring this area.

“How this is done in the brain is pretty much completely unknown. Synapses adjust themselves, but we don’t have a clear picture for what the algorithm of the cortex is,” says LeCun. “We know the ultimate answer is unsupervised learning, but we don’t have the answer yet.” – Daniela Hernandez

Investing in Robotics and AI Companies

Here are some AI (and robotics) related companies to think about.

I’m not saying you should buy them (now) or sell for that matter, but they are definitely worth considering at the right valuations.

Think about becoming an owner of AI and robotics companies while there is still time. I plan to buy some of the most obvious ones (including Google) in the ongoing market downturn (2016-2017).

Top 5 most obvious AI companies

  • Alphabet (Google)
  • Facebook (M, Deep Learning)
  • IBM (Watson, neuromorphic chips)
  • Apple (Siri)
  • MSFT (skype RT lang, emo)
  • Amazon (customer prediction; link to old article)

Yes, I’m US centric. So sue me 🙂

Other

  • SAP (BI)
  • Oracle (BI)
  • Sony
  • Samsung
  • Twitter
  • Baidu
  • Alibaba
  • NEC
  • Nidec
  • Nuance (HHMM, speech)
  • Marketo
  • Opower
  • Nippon Ceramic
  • Pacific Industrial

Private companies (*I think):

  • *Mobvoi
  • *Scaled Inference
  • *Kensho
  • *Expect Labs
  • *Vicarious
  • *Nara Logics
  • *Context Relevant
  • *MetaMind
  • *Rethink Robotics
  • *Sentient Technologies
  • *MobileEye

General AI areas to consider when searching for AI companies

  • Self-driving cars
  • Language processing
  • Search agents
  • Image processing
  • Robotics
  • Machine learning
  • Experts
  • Oil and mineral exploration
  • Pharmaceutical research
  • Materials research
  • Computer chips (neuromorphic, memristors)
  • Energy, power utilities
