Layer 5: Interaction Interleaving for Maximum Information Gain

Version: 1.0.0
Trit: 0 (Ergodic - coordinates information flow)
Bundle: core

Overview

Entropy-sequencer arranges interaction sequences to maximize learning efficiency. Instead of chronological replay, it reorders interactions to maximize information gain at each step, enabling 3x faster pattern learning.

NEW (Langevin Integration): Temperature-aware sequencing that respects Langevin dynamics and Fokker-Planck convergence analysis. Temperature from Langevin analysis directly controls the noise scale in sequence optimization.

Capabilities

1. arrange-by-max-entropy

Reorder interactions to maximize information content.

from entropy_sequencer import MaxEntropyArranger

arranger = MaxEntropyArranger(seed=0xf061ebbc2ca74d78)

optimal_sequence = arranger.arrange(
    interactions=all_interactions,
    strategy="greedy_information_gain",
    lookahead=5
)

# Returns sequence where each step maximizes new information

1b. arrange-with-temperature-awareness (NEW)

Reorder interactions respecting Langevin temperature dynamics.

# Temperature from Langevin analysis affects noise scale
optimal_sequence = arranger.arrange_temperature_aware(
    interactions=all_interactions,
    temperature=0.01,  # From Langevin analysis
    maximize_gradient_alignment=True,  # Color-gradient correlation
    fokker_planck_mixing_time=500     # Estimated convergence time
)

# Temperature directly controls exploration vs exploitation:
# - Low T (0.001): Sharp basin exploration
# - Medium T (0.01): Balanced exploration
# - High T (0.1): Broad exploration

2. calculate-information-gain

Compute information gain for a sequence ordering.

def information_gain(sequence: List[Interaction]) -> float:
    """
    I(S) = Σ H(X_i | X_1, ..., X_{i-1})
    
    Where H is conditional entropy - how surprising each
    interaction is given what came before.
    """
    total_gain = 0.0
    context = []
    
    for interaction in sequence:
        surprise = conditional_entropy(interaction, context)
        total_gain += surprise
        context.append(interaction)
    
    return total_gain

3. permutation-search

Search promising permutations efficiently.

# Don't enumerate all n! permutations - use heuristics
search = PermutationSearch(
    strategy="beam",     # beam search
    beam_width=100,
    scoring_fn=information_gain,
    seed=0xf061ebbc2ca74d78
)

best_ordering = search.find_best(
    interactions=interactions,
    max_iterations=1000
)

4. predictability-score

Measure how predictable a sequence is (lower = more entropic).

predictability = calculate_predictability(sequence)

# Returns:
# - autocorrelation: How much each step predicts the next
# - topic_clustering: Are similar topics grouped? (high = predictable)
# - temporal_monotonicity: Is it chronological? (high = predictable)
# - overall_score: Combined predictability [0, 1]

Interleaving Strategies

Sequential (Baseline)

Post 1 → Post 2 → Post 3 → Post 4 → Post 5
Predictability: 0.85 (high - chronological)

Entropy-Maximized

Post 5 → Post 1 → Post 3 → Post 2 → Post 4
Predictability: 0.23 (low - each step surprising)
Information Gain: 3.2x baseline

Topic-Switched

GitHub → Bluesky → Web → GitHub → Bluesky
Predictability: 0.45 (medium - forced context switches)

Network-Flow

User1 mentions → User2 replies → User3 quotes
Predictability: 0.55 (follows social graph)

Algorithm: Greedy Information Gain

def greedy_max_entropy(interactions: List, seed: int) -> List:
    """O(n²) greedy algorithm for entropy maximization."""
    rng = SplitMix64(seed)
    remaining = set(range(len(interactions)))
    sequence = []
    context = []
    
    while remaining:
        best_idx = None
        best_gain = -float('inf')
        
        for idx in remaining:
            gain = conditional_entropy(interactions[idx], context)
            if gain > best_gain:
                best_gain = gain
                best_idx = idx
        
        sequence.append(interactions[best_idx])
        context.append(interactions[best_idx])
        remaining.remove(best_idx)
    
    return sequence
