ref: -2004 tags: neural synchrony binding robot date: 09-13-2020 02:00 gmt revision:0 [head]

PMID-15142952 Visual binding through reentrant connectivity and dynamic synchronization in a brain-based device

  • Controlled a robot with a complete (for the time) model of the occipital-inferotemporal visual pathway (V1 V2 V4 IT), auditory cortex, colliculus, 'value cortex'.
  • Synapses had a timing-dependent assoicative BCM learning rule
  • Robot had reflexes to orient toward preferred auditory stimuli
  • Subsequently, robot 'learned' to orient toward a preferred stimuli (e.g. one that caused orientation).
  • Visual stimuli were either diamonds or squares, either red or green.
    • Discrimination task could have been carried out by (it seems) one perceptron layer.
  • This was 16 years ago, and the results look quaint compared to the modern deep-learning revolution. That said, 'the binding problem' is imho still outstanding or at least interesting. Actual human perception is far more compositional than a deep CNN can support.

ref: Prescott-2006.01 tags: basal_ganglia action selection motor control robot date: 03-01-2012 17:56 gmt revision:4 [3] [2] [1] [0] [head]

PMID-16153803[0] The robot basal ganglia: action selection by an embedded model of the basal ganglia

  • they implemented a model of the basal ganglia in a robot. The model switches between competing (hypothetical) actions based on input salience. There are only a possible actions in their robot.
  • they reiterate the common conception that the basal ganglia are implicated in action selection: what to do next ( also mentioned are other functions - perception and cognition working memory and many other aspects of motor function. )
  • huh, interesting : cognitive psychologists have discovered that when an observable system has more than three interacting parts, it becomes very difficult for human minds to predict accurately how that system will change over time. (!!!) I dig disclaimers like this.
    • therefore, very limited understanding can be gleaned from informal, box and arrow style models.
      • I think the same is true of many biological analysis - including analysis of the immune and nervous systems - it needs to be at a much higher level of quantification
    • they also say that a model must be validated by placing it within the entire behavioral system.
  • the basal ganglia seem to be suitable for switching between competing channels & providing the required clean selection of a winner.
    • (1) striatal cells have up and down states, and can only switch between them with heavy coincident inputs.
    • (2) selective local inhibition between channels.
    • (3) dopamine innervation D1 = exitation; D2 = inhibition. I never really got how this enters their model; figure 1 seems like it would describe it, but it needs more math :)
    • (4) feedforward off-center, on surround network. they ref some other work..
      • I still don't feel like their explanation is the best (they use kinda wishy-washy terms) - though it is a step in the right direction.
  • people with schizophrenia sometimes switch cognitive focus rapidly; schizo is though to be due to a dopamine imbalance. Same problem with ADD.
    • treatment for ADD: amphetamine (blocks monoamine transporter, increases extracellular concentration of DA), ritalin. Both allow for heightened concentration: once you select a task, you stick with 'it' (the thought / prediction pathway) for longer. Dopamine is definintely involved in action selection, duhh.
    • their model supports this behavior: If the tonic dopamine level is very low, the robot has difficulty initiating actions; if the DA level is high, then it tends to select more than one action at the same time. (wait.. this implies that DA is too high in people with ADD? what? perhaps this is a consequence of the two different types of DA receptors? )
  • (...) basal ganglia - thalamo-cotrical loops my act to provide a positive feedback pathway that can maintain appropriate level of salience to selected behavior.
  • much of the input to the basal ganglia comprises collateral fibers from motor regions that project to the spinal cord and brainstem structures.
    • activity changes in the BG occur slightly after the beginning of EMG activity (good evidence!) Such signals may be important for controlling the maintenance and termination of selected behavior.

My thoughts:

  • what if the STN is involved in controlling the stability of neuronal activity - that is, preventing motor feedback instability by knocking down the gain. (whereas the cerebellum is involved in the balance and coordination interpretations of stability)
    • Normally, the human motor system is very stable, but when you lack dopamine innervation, you both cannot move (become very rigid) & have tremor (an inability to control cyclical oscillations).
      • That is, perhaps oscillation is due to a intrinsic inability to modulate gain.
      • more likely it is a manifestation/symptom of pathological activity in the control loop.

Sony Robots:

  • youtube video - the robots are amazingly articulated (including the hips/ankles) , and the sequence of movements is quite long!
  • Sony QRIO (Quest for cRIOsity) entertainment robot.
    • QRIO video
    • One of the first robots that is able to run (both feet off the ground at one time).
    • Stereo Vision
    • Adaptive balance to protect the all-important head
    • Sophisticated AI : Interestingly, when they’re doing demonstrations, they have found that the AI in QRIO is so strong that if you haven’t been friendly with it before hand, for examples, by not kicking back a football it kicks to you, it will refuse to do what you ask it in the demonstration. Effectively it is expressing its annoyance. source
    • Not for commercial sale: too expensive to manufacture - approximately $50k. Only about 100 in existence. Seems to be somewhat of a 'halo technology'.
      • Startes circa 2002, discontinued January 26 2006.
  • Sony AIBO (Artificial Intelligence RObot)
    • able to learn from the environment.
    • Sounds created by Nobukazu Takemura; has a MIDI processor on-board.
    • built-in wireless LAN.
    • total 20 DOF
    • single VGA resolution camera for vision
    • ~ $2k price, 130k sold so far.
    • Sony released a development kit at the behest of the community; AIBO is useful as it is a good platform for AI & robotics research.
  • Industrial robots:
    • SCARA robot (4 axis?):

Robots & others designed & made at the Tokyo Institute of Technology (from the Hirose / Fukushima Robotics lab)

  • snake robots
  • gripper
      • with human-crushing, kid-grabbing power. frightening!
  • walking robots
      • -- 1994. can climb a 70 degree slope!
    • --window washing robot.
    • -- skating robot: walk ; skate. movie -- wow!
  • wheeled robots
  • other
    • -- prismatic, variable-speed eccentric linear drive. sorta like harmonic drive for linear motion? link

these guys use the blackfin, too: http://www.surveyor.com/ check out the board - very clean and neat!

The robot itself - with tank treads and a radio - costs $465

http://www.berndporr.me.uk/iso3_sab/

  • idea: have a gating signal for the hebbian learning.
    • pure hebbian learning is unsable; it will lead to endless amplification.
  • method: use a bunch of resonators near sub-critically dampled.
  • application: a simple 2-d robot that learns to seek food. not super interesting, but still good.
  • Uses ISO learning - Isotropic sequence order learning.
  • somewhat related: runbot!
