I wonder if theres any biological circuit that could implement a network that outputs weights to operate anothee network. I think it falls under the realm of dynamic gating. I know there are the so gain field neurons that sorta implement this in a similar way to HTM but I believe it would have a p…

Attention has to work somehow. I was fancying these days on an implementation variant (with no regards whether it makes sense biologically) Gating methods usually either route input through one or a couple small “specialist” sub-networks (out of dozens-hundreds of sub-networks) at every layer, or…

[image] JarvisGoBrr: I wonder if theres any biological circuit that could implement a network that outputs weights to operate another network. You may want to to take a look at the neuromodulatory system. I think it’s behaving in a way that is similar to what you are looking for. @Bitking ca…

Asking GPT-4: What are the targets of subcortical neuromodulators in the cortex ChatGPT Subcortical neuromodulators are chemicals produced in certain regions of the brain that regulate neuronal activity and can alter the way the brain processes information. Common neuromodulators include dopamine…

Can you differentiate between direct physical connections and blood born neurotransmitters? ChatGPT Sure, I can clarify the difference between these two mechanisms of neural signaling. Direct Physical Connections: Neurons in the brain and the rest of the nervous system communicate via direct ph…

More on this from an older post: [image] What does "the receptive field center" mean in SP? Lounge Thanks - I have been studying this stuff for a long time - since the 1970s. You are mixing different parts of neural theory in places where they don’t apply so I am not surp…

[image] JarvisGoBrr: I wonder if there are circuits with synapses that connect directly to dentrite branches or something similar anywhere in the brain. I think that the OP is thinking like a digital computer engineer where a signal path is gated from one area to another. I don’t think of pro…

[image] Bitking: I think that the OP is thinking like a digital computer engineer where a signal path is gated from one area to another. I was actually thinking more like a graphics programmer where you need to transform data using a reference frame before you can render it. Its just a guess…

I am not aware of any structure like that in the cortex.

Chiming in a few thoughts here… Basically any neuron synapses triggered below activation threshold can “amplify” any signal from the other synapses. e.g. a neuron triggered by a duck, could get a continuous input from both higher levels expectations “a duck is likely near the shore” and visual …

[image] cezar_t: about MNIST performance - I’m pretty sure fovea vision makes image recognition pretty insensitive to position and, to a lesser degree, to its size. Instead of treating vision as a passive sensory organ, I would consider it as an agent, capable to actively move into, search for s…
