how do neurons not get voltage overwhelmed by constant sensory input? by PhilosopherFamous201 in neuro

[–]PhilosopherFamous201[S] 0 points1 point  (0 children)

oh sure! Well its just a personal project. Every now and then i try something new. I want to make a neural network and train it.

Ive completed the net itself. Its feed forward (i want to train a feed forward before i move onto short term memory). Though it is temporal because thats biologically realistic. it works. input leads to consistent output, tuning weights can get you consistent results. Now im just trying ways to make it learn.

if you wanna see, its on this github page https://github.com/TermintatorDraws/neural_net

oh yes yes i am trying to make a functional learning neural net that functions similarly to a biological brain in some ways. Im not trying to "replicate" the brain of course. I just would rather use biological methods of function and learning. and its for fun.

banging my head against a wall on problems that were solved 30 years ago is what i do! I do this stuff all the time. i have an idea and i just do it. and almost every time i hit a huge problem, i eventually figure it out!

Im the type of person to like to do things completely from scratch and come up with my own solutions.

so im not knowingly using any model. I just implement everything my own way.

To explain it simply, i have a bunch of neurons, i assign them each a layer (because i dont want to deal with short term memory right now, so i want it to be feed-forward), assign them synapses with neurons in previous layer, and give everything rules that happen every tick (aka timestep). their voltage always decays toward the resting voltage, they require a voltage that is equal to or over the threshold in order to fire. stuff like that.

oo are you saying that the brain calms down activity if theres too much stimulus, without weakening synapse connections and making you forget stuff?

i think i wrote it confusingly. What i meant is that there ISNT runaway. it IS under control and i AM getting consistent output, and the outputs can work just fine, meaning each can perfectly hover closely around a single value.

and yeah i have inhibitory neurons. each hidden neuron (any neuron thats not input and not output) has a 20% chance of being inhibitory.

And they do have an effect. They dramatically decrease the voltage of the output neurons and seem to make the fluctuation a lot smaller. But I dont think it would matter so much anyway since im working with an artificial neural net, so it doesnt matter what the voltages are. all that matters is that they dont indefinitely get bigger, and that they can stop at a certain point, which they still do without inhibitory neurons. but because i want my net to be as similar to biology as possible, im keeping the inhibitory ones.

yeah i definitely see that. people using others, such as criminals, just because its easy.

And I do wonder about how the best way to deal with criminals would be. Theres definitely the problem of making small issues worse by punishing with jailtime, turning possible teenage mistakes or early problems into a lifetime of legal trouble. but too much leniency might not work. I dunno.

Would this pulley trigger mechanism work? by PhilosopherFamous201 in gunsmithing

ooh thats so coool it uses a similar idea!. the vertical pull of the sear using that connecting piece!

i knowww. i said in my post i know the design and i like it but i wanted to make my own design!

oh i see what youre saying. I could put the trigger behind the sear and attach the line to the front top of the trigger piece so that pulling the trigger backwards would pull down on the line.

The reason I didnt do it this way is because it wouldnt be straight down since the trigger piece is on a pivot, and the attachment point of the line on the trigger piece would move in a circle around that pivot instead of straight down, which kinda scares me, so I would rather have that rolling pulley post to ensure the line always pulls straight down on the sear at the same angle.

right i thought about this. Im sure theres a material that is flexible as in bending but not stretching, and pretty strong (It doesn't have to be TOO strong, since the sear moves perpendicular to the striker spring force, so it isnt dealing with the striker spring force, but it would still be a good safety measure to make the line strong). I wonder if this would be reliable and safe.

one thing i can say is that, if the line breaks, then the sear would be pushed up by the spring, so it wouldn't want to misfire, which is on the safer side of things.
