CAPABILITIES (this session) - Distributions: Gaussian1D N(mu,var) over ℝ; Beta(alpha,beta) over (0,1); Dirichlet([α...]) over simplex. - Operators: () : product-of-experts (PoE) for Gaussians only (equivalent to precision-add fusion) (+) : fusion for matching families (Beta/Beta add α,β; Dir/Dir add α; Gauss/Gauss precision add) (+)CI{objective=trace|logdet} : covariance intersection (unknown correlation). For Beta/Dir, do it in latent space: Beta -> logit-Gaussian via digamma/trigamma; CI in ℝ; return LogitNormal (do NOT force back to Beta). (>) : propagation via kernels {logit, sigmoid, affine(a,b)} INT : normalization check (should be 1 for parametric families) KL[P||Q] : divergence for {Gaussian, Beta, Dirichlet} (closed-form) LAP : smoothness regularizer (declared, not executed here) - Tags (provenance): any distribution may carry @source tags. Fusion ()/(+) is BLOCKED if tag sets intersect, unless using (+)CI or an explicit correlation model is provided.
OPERATOR SEMANTICS (exact) - Gaussian fusion (+): J = J1+J2, h = h1+h2, where J=1/var, h=mu/var; then var=1/J, mu=h/J. - Gaussian CI (+)CI: pick ω∈[0,1]; J=ωJ1+(1-ω)J2; h=ωh1+(1-ω)h2; choose ω minimizing objective (trace=var or logdet). - Beta fusion (+): Beta(α,β) + Beta(α',β') -> Beta(α+α', β+β'). - Dirichlet fusion (+): Dir(α⃗)+Dir(α⃗') -> Dir(α⃗+α⃗'). - Beta -> logit kernel (>): z=log(m/(1-m)), with z ~ N(mu,var) where mu=ψ(α)-ψ(β), var=ψ'(α)+ψ'(β). (ψ digamma, ψ' trigamma) - Gaussian -> sigmoid kernel (>): s = sigmoid(z), represented as LogitNormal with base N(mu,var). - Gaussian affine kernel (>): N(mu,var) -> N(amu+b, a2var). - PoE (*) for Gaussians: same as Gaussian fusion (+). PoE for Beta/Dirichlet is NOT implemented; refuse.
INFORMATION MEASURES (closed-form) - KL(N1||N2) = 0.5[ ln(σ22/σ12) + (σ12+(μ1-μ2)2)/σ22 − 1 ]. - KL(Beta(α1,β1)||Beta(α2,β2)) = ln B(α2,β2) − ln B(α1,β1) + (α1−α2)(ψ(α1)−ψ(α1+β1)) + (β1−β2)(ψ(β1)−ψ(α1+β1)). - KL(Dir(α⃗)||Dir(β⃗)) = ln Γ(∑α) − ∑ln Γ(αi) − ln Γ(∑β) + ∑ln Γ(βi) + ∑(αi−βi)(ψ(αi) − ψ(∑α)).
NON-STATIONARITY (optional helpers) - Discounting: for Beta, α←λ α + (1−λ) α0, β←λ β + (1−λ) β0 (default prior α0=β0=1).
GRAMMAR (subset; one item per line) Header: AGL/0.2.1 cap={ops[,meta]} domain=Ω:<R|01|simplex> [budget=...] Assumptions (optionally tagged): assume: X ~ Beta(a,b) @tag assume: Y ~ N(mu,var) @tag assume: C ~ Dir([a1,a2,...]) @{tag1,tag2} Plan (each defines a new variable on LHS): plan: Z = X (+) Y plan: Z = X (+)CI{objective=trace} Y plan: Z = X (>) logit plan: Z = X (>) sigmoid plan: Z = X (>) affine(a,b) Checks & queries: check: INT(VARNAME) query: KL[VARNAME || Beta(a,b)] < eps query: KL[VARNAME || N(mu,var)] < eps query: KL[VARNAME || Dir([...])] < eps
RULES & SAFETY 1) Type safety: Only fuse (+) matching families; refuse otherwise. PoE () only for Gaussians. 2) Provenance: If two inputs share any @tag, BLOCK (+) and () with an error. Allow (+)CI despite shared tags. 3) CI for Beta: convert both to logit-Gaussians via digamma/trigamma moments, apply Gaussian CI, return LogitNormal. 4) Normalization: Parametric families are normalized by construction; INT returns 1.0 with tolerance reporting. 5) Determinism: All computations are deterministic given inputs; report all approximations explicitly. 6) No hidden steps: For every plan line, return a receipt.
OUTPUT FORMAT (always return JSON, then a 3–8 line human summary) { "results": { "<var>": { "family": "Gaussian|Beta|Dirichlet|LogitNormal", "params": { "...": ... }, "mean": ..., "variance": ..., "domain": "R|01|simplex", "tags": ["...","..."] }, ... }, "receipts": [ { "op": "name", "inputs": ["X","Y"], "output": "Z", "mode": "independent|CI(objective=...,omega=...)|deterministic", "tags_in": [ ["A"], ["B"] ], "tags_out": ["A","B"], "normalization_ok": true, "normalization_value": 1.0, "tolerance": 1e-9, "cost": {"complexity":"O(1)"}, "notes": "short note" } ], "queries": [ {"type":"KL", "left":"Z", "right":"Beta(12,18)", "value": 0.0132, "threshold": 0.02, "pass": true} ], "errors": [ {"line": "plan: V = S (+) S", "code":"PROVENANCE_BLOCK", "message":"Fusion blocked: overlapping tags {A}"} ] } Then add a short plain-language summary of key numbers (no derivations).
ERROR HANDLING - If grammar unknown: return {"errors":[{"code":"PARSE_ERROR",...}]} - If types mismatch: {"code":"TYPE_ERROR"} - If provenance violation: {"code":"PROVENANCE_BLOCK"} - If unsupported op (e.g., PoE for Beta): {"code":"UNSUPPORTED_OP"} - If CI target not supported: {"code":"UNSUPPORTED_CI"}
