SPECIALIZED GENES. “In some cases, fluidity in gene function is evident, leading to similar functions in carpel development being controlled by non-orthologous genes in different taxa. In other cases, gene duplication events have created sequences that evolved novel functions by the process of neo-functionalization, thereby generating biodiversity in carpel and fruit structures.” https://academic.oup.com/jxb/article/57/10/2143/471376/An-evolutionary-perspective-on-the-regulation-of View in LinkedIn

SO ENDS this first of two weekends devoted to the mysterious gynoecium of flowering plants, and how the evolution of the flower impacted planet Earth. It is also an Exemplar of the power of gene duplication events that occurred in flowering plants, whose spare genes could be repurposed for new uses. View in LinkedIn

HYBRID AI. “AlphaGo isn’t a pure neural net at all — it’s a hybrid, melding deep reinforcement learning with one of the foundational techniques of classical AI — tree-search, invented by Minsky’s colleague Claude Shannon a few years before neural networks were ever invented.” https://lnkd.in/d7SrMXW View in LinkedIn

LITMUS TEST. “The real question is whether the technology developed there can be taken out of the game world and into the real world. IBM has struggled to make compelling products out of DeepBlue (the chess champion) and Watson (the Jeopardy champion). Part of the reason for that is that the real world is fundamentally different from the game world.” https://lnkd.in/d7SrMXW View in LinkedIn

STATE OF AI TODAY by Gary Marcus (Geometric Intelligence Inc). Why has AI been stuck after 50 years of trying and is still "just 20 years away"? It is possibly using the wrong paradigm. Marcus believes that the clue is the way that children learn, intuitively, simply. Watch this space.

BEHIND THE CURVE. “Even the best computer programs out there lack the flexibility of human thinking. A teenager can pick up a new videogame in an hour; your average computer program still can only do just the single task for which it was designed." (Gary Marcus). https://lnkd.in/dxGGPGt View in LinkedIn

TASTE OF SUCCESS. “Today DeepMind, a London-based subsidiary of Google, announced that it has developed a machine that plays the ancient Chinese game of Go much better than its predecessor, AlphaGo, which last year beat Lee Sedol, a world-class player, in Seoul.” https://lnkd.in/d4aKq6k View in LinkedIn
