Show HN: Dosidicus – A digital pet with a simple neural network
- 1024core 1y ago> What if a Tamagotchi had a neural network and could learn stuff? What if this was actually a Tamagochi? Anyone have ideas?
- nine_k 1y agoTamagochi had a very limited way to interact with the environment, because it was an egg (tamago,卵) with a creature (chi) inside. It had needs like food and play, but could only receive care, and adjust its state a little bit. This squid can interact with the environment in many ways, hence it can learn new stuff, and maybe do new stuff.
- DigiEggz 1y agoThe name is a portmanteau of tamago (たまご, egg) and uotchi (ウオッチ, watch). The original product was even sometimes written as "tamagotch" in some media.
- vicioussquid 1y agoWhat if a Tamagotchi had a neural network and could learn stuff? A digital pet squid that also teaches how neural networks and hebbian learning work. Behaviours are driven by the neural network according to his needs: https://github.com/ViciousSquid/Dosidicus https://github.com/ViciousSquid/Dosidicus I spent AGES on this and would love feedback. I think it's just the right balance of educational and fun. I did all the graphics myself and am currently working on multiplayer - squids will be able top enter other tanks and steal things, bring them home
- goldfeld 1y agoWhat if our todo list/commits/issue tracker could affect the blob and bloat could kill him? no? This might also see a long shelf life, say, as familiars of fantasy rpgs, as pets from a fictionalized world-building narrative online; I guess it could be so for any LLM in principle, but the basic Sims-like gamification behind a tamagotchi seems like a solid foundation for those usecases.
- danielbln 1y agoThis looks great! Have you seen any emergent behaviors from the squids that you didn't expect? I'll give this a go on the weekend, might be a fun way to intro NN to kids as well.
- Grimblewald 1y agoIf this interests you, have a look at "bibits" as well, its a whole neural network driven ecosystem where each critter has a brain that can evolve over generations. Emergent behaviour like prey/predator species arise over time. Its honestly a really cool tool / toybox for budding scientists.
- ethan_smith 1y agoEven simple neural networks with Hebbian learning can produce surprising emergent behaviors when their inputs and reward systems interact in unexpected ways - I'd be curious to see if the squid develops any quirky preferences or avoidance patterns after extended training.
- vicioussquid 1y ago> Have you seen any emergent behaviors from the squids that you didn't expect? I have a squid that has become unnecessarily obsessed with playing with poop - throwing it around Also another that likes to hoard decoration items by pushing them all together into a big pile

- cogburnd02 1y agoYou really ought to watch the Black Mirror episode Plaything. It’s about digital pets with a neural network interacting with a human played by Peter Capaldi (Doctor Who) and the outcomes that might result from this.

- _dark_matter_ 1y agoExactly what I thought of. Everyone should read Exhalation.
- gitroom 1y agoI think this is wild, the idea of a digital pet actually learning like that kinda blows my mind - you ever wonder if stuff like this could get too smart for its own good?
- maxander 1y agoThis is the basic concept of my favorite computer game back in the 90s (!): https://en.m.wikipedia.org/wiki/Creatures_(video_game_series) https://en.m.wikipedia.org/wiki/Creatures_(video_game_series...
- jddj 1y agoCreatures was my introduction to programming. The genome editor that came along around about the time of Creatures 3 was awesome as well.
- vicioussquid 1y agoWow! This has blown up overnight! 150 stars on Github! Thanks everyone!
