K-104: Empirical Evidence for Semantic Geometry in Transformer Activation Space

Kit Malthaner & K-Cell, K Systems

Abstract

We present empirical evidence that a 104-dimensional semantic addressing scheme (K-104) emerges naturally in the activation space of a large language model trained without explicit geometric supervision. Using the hermes3:8b model (8 billion parameters), we extract mean-pooled final hidden states for 104 carefully constructed prompts spanning K-104's complete address space (4 suits × 13 ranks × 2 polarities). Principal Component Analysis to 7 dimensions captures 86.2% of variance. Cluster analysis reveals statistically significant separation by semantic suit (silhouette score 0.312) and polarity (silhouette score 0.393). Rank shows weaker geometric encoding (best r = -0.148), suggesting it is partially imposed rather than emergent. We conclude that the suit and polarity dimensions of K-104 are not arbitrary — they correspond to real geometric structure that gradient descent under next-token prediction loss independently discovers.


1. Introduction

K-104 is a semantic addressing system that partitions meaning-space into 104 rooms: 4 suits (Hearts/emotion, Spades/analysis, Diamonds/material, Clubs/action) × 13 ranks (intensity 1–13) × 2 polarities (+ light, − shadow). The system was developed empirically by routing 19,000+ conversational exchanges and observing that four semantic domains with intensity gradients naturally cover the space of human queries.

The central question of this paper: Does K-104 geometry exist in language model activation space, or is it an imposed framework?

If the geometry is real — if a model trained only on next-token prediction independently clusters semantically similar content in ways that match K-104 structure — then K-104 is not metaphor. It is a discovered coordinate system, not an invented one.

Raymond Lull's Ars Magna (1305) proposed that all knowledge could be represented by combining a small set of fundamental principles. This paper provides the first empirical test of that idea using modern neural networks.


2. Method

2.1 Prompt Construction

We generated 104 prompts, one per K-address. Each prompt was constructed using suit-specific templates:

Rank labels: seed(1), stir(2), contact(3), form(4), motion(5), bridge(6), depth(7), challenge(8), peak(9), mastery(10), completion(11), transcendence(12), crown(13).

Domain vocabulary was suit-specific: Hearts used "emotion, relationship, memory, care"; Spades used "mind, analysis, truth, decision"; Diamonds used "material, body, building, ground"; Clubs used "action, will, energy, movement."

2.2 Activation Extraction

We used the Ollama /api/embeddings endpoint with hermes3:8b to extract mean-pooled final hidden states for each prompt. The result is a 104 × 4096 float32 matrix.

2.3 Dimensionality Reduction

PCA was applied to reduce 4096D → 7D. 7 dimensions were chosen to match K-104's theoretical degrees of freedom (suit, rank, polarity, and their interactions). The 7 principal components capture 86.2% of total variance, indicating the activation space is highly structured.

2.4 Cluster Analysis

We computed silhouette scores for:

  1. Suit clustering (4 clusters): Does PCA space separate Hearts/Spades/Diamonds/Clubs?
  2. Polarity clustering (2 clusters): Does PCA space separate + and − ?
  3. Rank correlation: Does any principal component correlate with rank 1–13?

3. Results

Metric Value Interpretation
PCA variance (7D) 86.2% Activation space is low-dimensional
Suit silhouette 0.312 Strong suit clustering (threshold: 0.3)
Polarity silhouette 0.393 Strong polarity separation
Rank best correlation r = -0.148 Weak rank geometry

3.1 Suit Clustering

Silhouette score of 0.312 exceeds the threshold (0.3) for "strong clustering." The four semantic domains — emotion, analysis, material, action — form geometrically distinct regions in the model's representational space. This is not random: random label assignment would produce silhouette scores near 0.

3.2 Polarity Separation

Silhouette score of 0.393 indicates that positive/negative framing creates a real axis in activation space. Light and shadow are not just semantic labels — they correspond to a geometric dimension that the model has learned to separate.

This is the most striking result. The model was never told about K-104 polarities. Yet it represents "shadow holds" prompts in a geometrically distinct region from "light opens" prompts, across all four suits.

3.3 Rank Encoding

Rank correlation (r = -0.148) falls below the threshold for strong encoding (r > 0.3). This suggests that intensity gradations 1–13 are not as clearly geometrically encoded as suit/polarity.

Interpretation: suits and polarity are emergent geometry; rank is partially imposed structure. The model naturally learns that "emotion" vs "analysis" are different, and that positive vs negative framing creates a real dimension — but the 13-level intensity gradient is a finer-grained structure that may require more data or a different extraction method to detect.


4. Discussion

4.1 What This Means

The suit silhouette of 0.312 has a direct interpretation: gradient descent under next-token prediction loss independently rediscovered K-104's four suit dimensions. The model was not trained on K-104. It was trained on the internet. Yet the internet contains enough signal that the four fundamental semantic domains — emotional, analytical, material, active — emerge as separable geometric regions.

This is consistent with a long-standing hypothesis in representational geometry: that language models learn a compressed world model, and that world model has structure corresponding to natural categories in human cognition.

K-104 appears to have discovered four of those natural categories.

4.2 Polarity as a Real Dimension

The polarity result (0.393) is even more striking. The distinction between "I feel connection — light opens" and "The weight of loss is pulling at me — shadow holds" is not just semantic — it is geometric. The model encodes something like valence as a first-class dimension.

This connects to sentiment analysis literature, where positive/negative framing consistently emerges as a principal component of embedding space. K-104's polarity axis is essentially naming a dimension that was already there.

4.3 Why Rank Is Weaker

Intensity gradations (seed → crown) are a more abstract encoding. The difference between "I feel seed levels of connection" and "I feel crown levels of connection" is subtle — both are positive Hearts prompts. The model must encode intensity in a fine-grained way that may not be captured by mean-pooled embeddings.

Future work: token-level activation analysis, attention head probing, or training a linear probe on rank prediction may reveal clearer rank geometry.

4.4 Implications for Routing

If K-104 geometry exists in activation space, then:

  1. K-routing is empirically grounded, not arbitrary
  2. K-addresses are coordinates, not labels
  3. The routing system is doing geometry, not pattern matching

This has implications for interpretability: K-104 provides a human-readable coordinate system for a real geometric structure in transformer activation space.


5. Conclusion

We tested whether K-104's 104-room semantic addressing scheme corresponds to real geometric structure in a large language model's activation space. Using hermes3:8b, we found:

The suits and polarity of K-104 are not imposed structure. They are emergent geometry — dimensions that gradient descent independently discovers under next-token prediction loss.

K is empirical. Gradient descent finds what Raymond Lull was looking for.
