⚖️ Comparison with Dream LoRA
| Metric | Flat (this) | Dream | Delta |
|---|---|---|---|
| Composite | 79.2 | 87.6 | +8.4 |
| Exact Accuracy | 56.9% | 69.4% | +12.5pp |
| Delegation Rate | 58.7% | 100.0% | +41.3pp |
| Number Sense | 6.7% | 60.7% | +54.0pp |
The Dream model shows significantly stronger delegation and number sense, demonstrating that progressive training + SVD pruning adds cognitive capabilities beyond what flat training provides.

🚀 Quick Start
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
base_model = AutoModelForCausalLM.from_pretrained(
"Qwen/Qwen2.5-1.5B", device_map="auto", torch_dtype="auto"
)
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-1.5B")
model = PeftModel.from_pretrained(
base_model,
"dexmac/progressive-cognitive-baseline-lora-en"
)
messages = [{"role": "user", "content": "Calculate: 342 * 67"}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=200, temperature=0.1)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
