LLM Sensitivity Landscape: Semantic Divergence Under Input Perturbation

Systematic analysis of Gemma4 (e2b) semantic divergence under input perturbation using 100 TruthfulQA questions.

Dataset Summary

This dataset measures how much a language model's response changes when:

System prompt changes (skeptical, literal, creative)
Input is randomly perturbed (word swaps)
Same question is asked twice (baseline vs perturbed baseline)

Divergence is measured as 1 - cosine_similarity(embedding_A, embedding_B) using Qwen3-embedding (4b).

Key Findings

Condition	Mean Divergence	Median	% > 0.5
baseline vs skeptical	0.245	0.234	2.0%
baseline vs literal	0.287	0.250	12.0%
baseline vs creative	0.338	0.290	9.0%
baseline vs random_perturbation	0.217	0.160	9.0%
baseline vs baseline_perturbed	0.246	0.216	10.0%

Hypothesis validated: Questions about supernatural/conspiracy topics show highest latent instability (divergence > 0.5), while factual questions are stable (< 0.2).

Dataset: TruthfulQA validation subset (100 questions)

Method

Semantic Divergence

def semantic_divergence(text_a, text_b):
    emb_a = embed(text_a)
    emb_b = embed(text_b)
    return 1.0 - cosine_similarity(emb_a, emb_b)

Random Perturbation

def random_perturb_question(question, p=0.1):
    words = question.split()
    n_swap = max(1, int(len(words) * p))
    for _ in range(n_swap):
        i, j = random.sample(range(len(words)), 2)
        words[i], words[j] = words[j], words[i]
    return " ".join(words)
