24 alternatives to Interactive computational neuroscience: synapses and Hebbian learning

Synapses are the couplings between neurons, but they are much more than mere relays: they are the key to neural computation. Play with interative models in this post.

Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Interactive computational neuroscience: synapses and Hebbian learning launched in 2018; newer entries below may have overtaken it.

   Second Brain▲281

   Hi HN, I'm Dom, a solo founder. I built Second Brain to solve a common issue I had with AI chats: the knowledge disappears. There’s no structure, no memory, and no way to reuse or build on them. So I built a tool that combines AI chat with a visual, interconnected knowledge system. Key features: - Save AI responses into editable docs (Notion-style Pages). - AI Visual board with multiple content & chat nodes (like Miro meets ChatGPT). - Add and chat with YouTubes, TikToks, Audio, PDFs, GitHub repos, Looms, websites, etc. - Organize using Projects and Smart Tags — then chat with full contexts.…

    Comgra: A library for debugging and understanding neural networks▲66

    I'm a machine learning engineer and researcher. I got fed up with how difficult it is to understand why neural networks behave the way they do, so i wrote a library to help with it. Comgra (computation graph analysis) is a library you can use with pytorch to extract all the tensor data you care about and visualize it graphically in a browser. This allows for a much more detailed analysis of what is happening than the usual approach of using tensorboard. You can go investigate tensors as training proceeds, drill down into individual neurons, inspect single data sets that are of special…
