## What This Is
|
| 24 |
|
| 25 |
+
TopologicalQwen is a 1.7B parameter model distilled from Qwen3-30B-A3B using **Topological Knowledge Distillation (TKD)** β a methodology that treats the teacher's output distribution over a concatenated token stream as a bounded variation (BV) function and decomposes knowledge transfer into three channels via the Mesh Fundamental Identity:
|
| 26 |
|
| 27 |
+
1. **Smooth distillation (AC component)** β Standard KL divergence over regions where the teacher's distribution varies continuously. This is what every other KD method does and stops at.
|
| 28 |
+
2. **Jump corrections (D^j f)** β Explicit correction terms at conceptual boundaries where the teacher's distribution exhibits discontinuities. These are the points where topic, register, or reasoning mode shifts β standard KD smears across them, losing structural information.
|
| 29 |
+
3. **Drift corrections (D^c f)** β The Cantor/singular-continuous component capturing gradual distributional drift that neither the smooth nor jump terms account for. This is the residual structure that emerges in generation quality.
|
|
|
|
|
|
|
|
|
|
|
|
|
| 30 |
|
| 31 |
+
Standard knowledge distillation only handles term (1). TKD captures all three.

## Training Methodology
|
| 48 |
|
| 49 |
+
The TKD pipeline has four phases:
|
| 50 |
|
| 51 |
+
**Phase 1 β Teacher logit caching:** Single forward pass through the teacher (Qwen3-30B-A3B) with top-k logit compression to disk. One pass, no repeated teacher inference.
|
| 52 |
|
| 53 |
+
**Phase 2 β DISC topology pass:** Vectorized discrepancy operator maps the knowledge manifold, identifying where the teacher's distribution has structural features (jumps, drift, curvature).
|
| 54 |
|
| 55 |
+
**Phase 3 β Topology-guided adaptive windowing:** Training windows cut at low-discrepancy positions rather than fixed stride. The topology tells you where to cut without losing information across boundaries.
|
| 56 |
+
|
| 57 |
+
**Phase 4 β Curriculum-ordered continuous KD:** Belt-fed training with proof-weighted loss. 55% cross-entropy with decaying proof weights (2.5Γ β 1.5Γ), 45% KL divergence at T=2.0. Proof weights amplify loss on reasoning-critical tokens.

## Usage
|
| 62 |
+
|
| 63 |
+
```python
|
| 64 |
+
from transformers import AutoModelForCausalLM, AutoTokenizer
|
| 65 |
+
|
| 66 |
+
model = AutoModelForCausalLM.from_pretrained(
|
| 67 |
+
"reaperdoesntknow/TopologicalQwen",
|
| 68 |
+
torch_dtype="auto",
|
| 69 |
+
device_map="auto"
|
| 70 |
+
)
|
| 71 |
+
tokenizer = AutoTokenizer.from_pretrained("reaperdoesntknow/TopologicalQwen")
|
| 72 |
+
|
| 73 |
+
messages = [{"role": "user", "content": "Derive the Euler-Lagrange equation from the principle of stationary action."}]
|
| 74 |
+
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
|
| 75 |
+
inputs = tokenizer(text, return_tensors="pt").to(model.device)
|
| 76 |
+
output = model.generate(**inputs, max_new_tokens=1024, temperature=0.7, top_p=0.9)
|
| 77 |
+
print(tokenizer.decode(output[0], skip_special_tokens=True))
|
| 78 |
+
```
|
| 79 |
+
|
| 80 |
+
## Why Topology Matters
|
| 81 |
|
| 82 |
+
Every knowledge distillation method in the literature treats the teacher's output as a smooth function and minimizes KL divergence globally. This works for the easy parts β regions where the teacher's distribution varies slowly. But language has structure: topic shifts, reasoning mode transitions, register changes. At these boundaries, the teacher's distribution jumps. Standard KD averages across these jumps, teaching the student a blurred version of the teacher's actual knowledge.
|
| 83 |
+
|
| 84 |
+
TKD uses the DISC (Discrepancy Calculus) framework to detect these structural features before training, then allocates capacity and loss weight accordingly. The result is a student that preserves the teacher's structural understanding, not just its surface statistics.
|
| 85 |
+
|
| 86 |
+
The empirical evidence: this model at 1.7B consistently produces responses with structural reasoning quality that standard distillation at the same parameter count does not achieve.
