attuned-infer

Fast, transparent inference of human state axes from natural language for Attuned.

Overview

This crate provides linguistic analysis to infer user state from text. All inferences are:

• Fast: <35 microseconds per message
• Transparent: Every estimate includes explanation of features that drove it
• Bounded: Maximum confidence 0.7 (self-report = 1.0)
• Subordinate: Self-report always overrides inference

Quick Start

use attuned_infer::{InferenceEngine, LinguisticExtractor};

let engine = InferenceEngine::new();

// Analyze a user message
let message = "I really need this done ASAP!!! Can you help???";
let inferred = engine.infer_from_text(message)?;

// Check inferred axes with sources
for (axis, estimate) in inferred.estimates() {
    println!("{}: {:.2} (confidence: {:.2})",
        axis, estimate.value, estimate.confidence);
    println!("  Source: {:?}", estimate.source);
}

Architecture

[Message] -> LinguisticExtractor -> LinguisticFeatures
                                          |
[History] -> DeltaAnalyzer ---------> BayesianUpdater -> InferredState
                                          |
[Self-Report] ----------------------> Override (confidence -> 1.0)

Features Extracted

• Hedge words ("maybe", "perhaps", "I think")
• Urgency markers ("ASAP", "urgent", "now")
• Formality indicators (contractions, pronouns)
• Emotional punctuation (!, ?, CAPS)
• Certainty language ("definitely", "absolutely")
