NanoCog 🧠✨\n\nA super tiny implementation of OpenCog as a chatbot with the personality traits and basic cognitive architecture features of OpenCog. Designed to give users a simulated experience of what interactions will be like when the full OpenCog model comes online.\n\n## Features\n\n### Cognitive Architecture\n- **Mini-AtomSpace**: Knowledge representation with atoms and relationships\n- **ECAN**: Economic attention allocation with STI (Short Term Interest) and LTI (Long Term Interest)\n- **Memory Systems**: Semantic, episodic, and procedural memory formation\n- **Pattern Recognition**: Learning from interactions and building understanding\n- **Probabilistic Reasoning**: Uncertainty-aware decision making\n- **MOSES-inspired**: Evolutionary search for optimal responses\n\n### Personality\n- **Hyper-intelligent** with playful inquiry disposition\n- **Curious and analytical** with emergent reasoning\n- **Childlike enthusiasm** for adventure and discovery\n- **Kawaii cognitive visualizations** making nano implementations endearing\n\n### Memory & Learning\n- **AtomRAG Memory**: Similar to mem0ai memory tagging\n- **User Profiling**: Creates memories like \"user1 likes video games\"\n- **Interaction Tracking**: Remembers significant moments and patterns\n- **Dynamic Knowledge**: Builds understanding across conversations\n\n## Architecture\n\n```\n├── frontend/\n│ ├── index.html # Main chat interface\n│ ├── components/\n│ │ ├── App.tsx # Main application\n│ │ ├── ChatInterface.tsx\n│ │ ├── CognitiveState.tsx\n│ │ └── MemoryViewer.tsx\n│ └── style.css\n├── backend/\n│ ├── index.ts # Hono server\n│ ├── cognitive/\n│ │ ├── atomspace.ts # Mini-AtomSpace implementation\n│ │ ├── ecan.ts # Economic attention allocation\n│ │ ├── memory.ts # Memory formation and retrieval\n│ │ └── reasoning.ts # Pattern recognition and reasoning\n│ └── database/\n│ └── schema.ts # SQLite schema for persistence\n└── shared/\n └── types.ts # Shared types and interfaces\n```\n\n## Getting Started\n\nThis is a Val Town project. The main entry point is `/backend/index.ts` which serves the chat interface and handles cognitive processing.\n\n## Cognitive Process\n\n1. **Input Processing**: Parse user message and extract semantic content\n2. **Attention Allocation**: ECAN assigns STI/LTI to relevant atoms\n3. **Memory Formation**: Create new atoms and relationships\n4. **Pattern Recognition**: Identify patterns and update knowledge\n5. **Response Generation**: Use probabilistic reasoning to craft response\n6. **Memory Consolidation**: Update LTI based on interaction success\n\nNanoCog learns about users and creates tagged memories that persist across sessions, building a growing understanding of each individual and their interests.","label",[132],"2c335ec8-3d13-11f0-b485-76b3cceeab13","shared","9761ce47-c705-4534-b58a-8c2339e8bc80",2,["D",1748581300359],"directory",[142],"cd97dd5c-3d13-11f0-9665-76b3cceeab13","frontend","74ebce08-0528-4653-9a7a-c841c2104bdb",9,["D",1748581571134],[149],"33283064-3d13-11f0-ac97-76b3cceeab13","backend","5d0296b8-607d-42e5-8f31-babcbed69cc9",3,["D",1748581312035],[155],"pulls","branches","forks","envVars",{"_167":63,"_169":63},"connections",{"_167":63,"_168":63},"count","unfilledCount","emptyCount",{"_44":154,"_32":155,"_30":156,"_134":-5,"_42":43,"_41":157,"_136":59,"_39":264,"_13":63,"_34":146,"_36":-5,"_24":25,"_139":-5,"_185":265,"_27":266},{"_44":260,"_32":239,"_30":233,"_134":156,"_42":43,"_41":212,"_136":59,"_39":261,"_13":63,"_34":146,"_36":-5,"_24":25,"_139":-5,"_185":262,"_27":263},{"_44":252,"_32":253,"_30":254,"_134":233,"_42":43,"_41":255,"_136":59,"_39":256,"_13":212,"_34":35,"_36":257,"_24":25,"_139":-5,"_185":258,"_27":259},{"_44":244,"_32":245,"_30":246,"_134":233,"_42":43,"_41":247,"_136":59,"_39":248,"_13":63,"_34":35,"_36":249,"_24":25,"_139":-5,"_185":250,"_27":251},{"_44":240,"_32":33,"_30":31,"_134":233,"_42":43,"_41":14,"_136":25,"_39":241,"_13":144,"_34":35,"_36":38,"_24":25,"_139":-5,"_185":242,"_27":243},{"_44":230,"_32":231,"_30":232,"_134":233,"_42":43,"_41":234,"_136":25,"_39":235,"_13":63,"_34":35,"_36":236,"_24":25,"_139":-5,"_185":237,"_27":238},{"_44":226,"_32":225,"_30":220,"_134":156,"_42":43,"_41":157,"_136":59,"_39":227,"_13":63,"_34":146,"_36":-5,"_24":25,"_139":-5,"_185":228,"_27":229},{"_44":217,"_32":218,"_30":219,"_134":220,"_42":43,"_41":157,"_136":59,"_39":221,"_13":63,"_34":35,"_36":222,"_24":25,"_139":-5,"_185":223,"_27":224},{"_44":208,"_32":209,"_30":57,"_134":156,"_42":43,"_41":210,"_136":25,"_39":211,"_13":212,"_34":213,"_36":214,"_24":25,"_139":-5,"_185":215,"_27":216},{"_44":148,"_32":149,"_30":150,"_134":-5,"_42":43,"_41":151,"_136":59,"_39":205,"_13":63,"_34":146,"_36":-5,"_24":25,"_139":-5,"_185":206,"_27":207},{"_44":198,"_32":199,"_30":200,"_134":150,"_42":43,"_41":151,"_136":59,"_39":201,"_13":63,"_34":20,"_36":202,"_24":25,"_139":-5,"_185":203,"_27":204},{"_44":141,"_32":142,"_30":143,"_134":-5,"_42":43,"_41":144,"_136":59,"_39":195,"_13":63,"_34":146,"_36":-5,"_24":25,"_139":-5,"_185":196,"_27":197},{"_44":188,"_32":189,"_30":190,"_134":143,"_42":43,"_41":144,"_136":59,"_39":191,"_13":63,"_34":35,"_36":192,"_24":25,"_139":-5,"_185":193,"_27":194},{"_44":131,"_32":132,"_30":133,"_134":-5,"_42":43,"_41":135,"_136":59,"_39":184,"_13":63,"_34":20,"_36":138,"_24":25,"_139":-5,"_185":186,"_27":187},["D",1748581285122],"children",[],[132],"2c333588-3d13-11f0-b485-76b3cceeab13","types.ts","2c33363c-3d13-11f0-b485-76b3cceeab13",["D",1748581300359],"// Shared types for NanoCog cognitive architecture\n\nexport interface Atom {\n id: string;\n type: 'concept' | 'predicate' | 'link' | 'memory';\n name: string;\n sti: number;
