Appendix: Algorithms & Technical Details

Spikuit draws on ideas from five fields. Each page covers the theory, how Spikuit applies it, and key references.

1. Computational Neuroscience — STDP, LIF, spreading activation, sleep consolidation
2. Cognitive & Developmental Psychology — forgetting curve, testing effect, ZPD, scaffolding
3. Spaced Repetition Systems — FSRS v6, grade mapping
4. Knowledge Graphs & Graph-Based ML — PageRank, APPNP, community detection
5. Information Retrieval & RAG — hybrid retrieval, conversational curation

For implementation specifics (algorithms, parameters, embedding pipeline):

• Implementation Details — APPNP math, STDP updates, LIF model, plasticity parameters, embedder config, tech stack
