0509 · Liu weipeng's TL Party [3]

Zheng Yu @ playmates SR

Beijing. Wudaokou. May 9.

The TL party topic continues to be logged out. [Read [1] and [2].

5. Led by scientists and engineers

One Party regards Sun as a typical scientist-led company, so Sun is not doing well. In this opinion, Huo Ju previously expressed in 5g that Sun is a scientist enterprise, not a market enterprise.

However, Douban seems to be led by engineers, but it does not actually look like it is led by product managers, or even led by abei.

Led by engineers. It is said that it is Netease youdao in China and Google in foreign countries.

However, it is hard to tell what is the difference between scientist-led and engineer-led here. If it is not market-oriented, there is no difference between them. If it is a research institution, scientists may think more about posting papers than the actual engineering details? However, in the company, identities of scientists and engineers are easy to confuse, so keso said in the same interview that "I agree Sun is an engineer-led technical company ".

6. Divergent reading Solution

Everyone knows that pongba advocates stumbleupon, which allows you to find that you are interested in so many topics that you did not know before, or even think you already know enough.

Pongba asked me what the next plan for getting together with SR and whether personalized reading was on the agenda.

In my opinion, finding The Best Content in Web requires finding enough trustworthy people in China. The TopLanguage group is regarded as a group of trusted people and cross-border users. Therefore, the information quality is still good and has a certain degree of divergence.

Without the recommendation, favorites, or sharing made by a large number of trusted people, there will be no good content associated after personalization.

Most of the domestic network favorites and bookmarking websites are abused by the SEOer, so the mining significance has been lost.

Without the basic data of data mining, personalized reading is impossible simply based on the data on Twitter and GReader Shared Items.

Playmates SR found A sub-optimal solution, but did not dare to open up this "trusted recommender List (A-List)", so the data is too small and too mainstream to make personalized recommendations.

The domestic imitation stumbleupon website has not reached the level of user participation, so it has not reached the stage of qualitative change. So now, China can only focus on networks composed of trusted people to notice things you don't know but may be interested in, such as scientific squirrel and TL.

Wonderful comments Aggregation

We will continue to list the results of the first two topics:

1: James:"

If TL is a brain, each of us is a neuron, and emails/twitter and so on are neural signal transmission.

"

2: Mo Huafeng:"

A. DNA may not be a simple program. The real control behavior is for various chemicals, neurotransmitters, proteins, enzymes, and so on, and their interactions,
These programs should act directly on the behavior. What DNA does is "metaprogramming", which guides the synthesis and metabolism of various substances and is a program for generating programs.

B.Natural evolution will not rely on complex rules(God loves KISS) evolutionary rules are built on other natural laws, or are embodied in other laws at all. Machines also rely on natural laws, and the rest of the question is how to use basic natural rules to guide machine evolution. Of course, you must first understand the natural law.

C. The brain functions are networked and functional partitions exist, but it cannot work when it leaves other partitions. Is a form between a partition and a network. There was a related article in the last issue of global science or new discoveries. A single cognitive behavior, such as listening, speaking, and motion, is not limited to a certain area. Any single cognitive behavior can mobilize almost all parts of the brain. However, the transfer and reconstruction of brain functions are limited, especially when the brain is damaged. The brain is more "expanding" some part of the brain function, "encroaching" another part. For example, in the Discovery program, a visually normal person has been wearing an eye mask for a week. It was found that her tactile sensitivity increased significantly, and MRI testing showed that some of her brain's visual cortex was "transferred" into the tactile cortex. This is also true for the blind. After a period of time, her visual cortex was changed to visual cortex again.

D.Human neural systems are "simple and complex ".Neurons are simple, but highly organizational associations make them extremely complex. The neural system has evolved for hundreds of millions of years, and basically no changes have been made to neural cells,Changes in scale and organization make a world of difference.

E. More and more evidence shows that almost all structures of the nervous system are decided by genes. Even possibilities and ways of thinking depend on genes. A few years ago, some experiments showed that the growth of neural cells was highly specific. Someone tried to cut down the brain top cover (responsible for Vision) of a bird's embryo, rotate it for 108 degrees, and then suture it. As a result, the SYN fibers emitted from the eyes to the top were also transferred to 180 degrees. This specificity may even exist between cortex columnar structures.
Early Development of the nervous system has completed construction and is driven by genes rather than the environment. The later growth of the nervous system is more about cropping and modifying, rather than constructing. It is more like parameter adjustment.

F. There is still too little basic investment, from elementary school to basic scientific research and talent training at the university. I have never seen any special forces with unstable guns.

"

3: joyfire:"

1. The automatic repair and reconnection functions in various areas of the brain are indeed strong, but they are also limited. The compensation mechanism is not hard to understand.

2. Innovation is not just like Apple, but it still requires a solid foundation. Our problem may be that the environment cannot truly "study for a long time ".
