Glossary

Terms used across AccuPredix documentation, the app, and the API.

A

Accuracy score
A 0–100 summary of forecast quality derived from portfolio WAPE. Higher is better. Shown in Simple view mode; technical users see raw WAPE instead.

Agency tier
Top plan for consultancies managing multiple client orgs. Includes Agency health, SSO, white-label reports, and unlimited quotas.

Analyst
Org role that can upload data, run forecasts, and apply overrides. Cannot manage billing or members.

API key
Secret token (X-API-Key header) for the public REST API. Created under API keys (Growth+).

B

Backtest / walk-forward
Historical evaluation where the model forecasts unseen periods and scores against actuals. Used to pick the best model per series and to calibrate P10/P50/P90 bands.

BFF (Backend for Frontend)
The app-backend service (accupredix_app) — handles auth, orgs, billing, and proxies forecast calls to the internal service.

Bias
Systematic over- or under-forecasting across the portfolio (mean error direction).

C

Canonical schema
Standard table layout (orders, optional masters and events) that all uploads and connectors must map into.

Cold start
A series with too little history for full seasonality learning; flagged and estimated with priors.

Conformal intervals
Prediction bands (P10/P50/P90) calibrated from backtest errors to achieve stated coverage.

Connector
Integration that syncs external system data into a workspace (Shopify, QuickBooks, ERP, SFTP).

Croston / TSB / ADIDA
Forecasting methods for intermittent demand (many zero months).

D

Dashboard
Portfolio summary page (/dashboard) with KPIs, demand shifts, and Growth+ analytic widgets.

Data drift
When a series' backtest error trends upward over recent runs — signal to retrain or investigate (RM-003, Growth+).

Data quality score
Grade A–D scorecard from history length, outliers, events, and quality checks (DASH-C-11).

Data region
Geographic storage choice set at org creation (e.g. EU). Locked after selection when data_region_locked is true.

Demand shift
Material change in projected demand vs the previous run; may trigger alerts.

DPA (Data Processing Agreement)
Contract required for Growth and Agency tiers; accepted under Settings → Privacy.

E

ETS / AutoETS
Exponential smoothing family; good for clear trend and seasonality.

Event
Calendar entry (promotion, stockout, shutdown) that masks or down-weights affected history during training.

F

Freemium
Free tier — limited workspaces and runs for evaluation.

Forecast run
One execution of the pipeline on a workspace's data; produces quantile forecasts and metrics.

G

Growth tier
Mid-market plan with API, connectors, scenarios, workflow, drift detection, and PWA.

H

Hierarchy reconciliation
Adjusting SKU forecasts so brand/category totals stay coherent (requires product_master).

I

Impersonation
Platform operator read-only view of a customer org (admin console).

Intermittent demand
Demand with many zero months; routed to specialist models (FC-011).

L

LightGBM
Gradient-boosted machine learning model; learns patterns across all series.

O

Org (organization)
Top-level tenant account — billing, members, and one or more workspaces.

Override
Manual replacement of model forecast for specific series/months; tracked separately from scenarios.

P

P10 / P50 / P90 (q10 / q50 / q90)
Low, median, and high quantile forecasts per month.

Portfolio WAPE
Weighted absolute percentage error aggregated across series in a run.

Probe (connector)
Test connection API that validates credentials before saving a connector.

R

RBAC
Role-based access control — owner, admin, analyst, viewer.

Run
See Forecast run.

S

Safety stock
Replenishment recommendation from forecast quantiles and optional margin data (FC-013-M).

Scenario
Temporary what-if adjustment to forecasts without retraining (Growth+).

Series
One forecastable time series — typically (customer_id, product_id).

Simple view
UI mode showing accuracy score and plain labels instead of WAPE.

SSO
Single sign-on via SAML/OIDC (Agency tier).

Starter tier
Entry paid plan with exports and push notifications.

Suspended (org)
Operator-blocked org; members and API cannot access tenant data.

T

Technical view
UI mode showing WAPE, bias, and raw metrics.

Tenant
Service-side isolation unit; maps 1:1 to an org with a dedicated database (accupredix_t_<slug>).

TFT
Temporal Fusion Transformer deep model — optional in Agency tier runs (FC-002-R).

W

WAPE
Weighted Absolute Percentage Error — primary forecast accuracy metric (lower is better).

Walk-forward
See Backtest.

Workspace
Container for one dataset and its forecast runs within an org.

Workflow
Approval, lock, review tasks, and @mentions for forecast governance (Growth+).
