# phi-2-DLEC

The DLEC (Distributive Layer Expansion Curve) methodology offers a novel approach to improving neural network models by focusing on the strategic duplication of certain effective layers. 
Developed with the aim of enhancing model performance, DLEC carefully identifies and amplifies the impact of key layers within the model's architecture. 

Below is a overview of the method and its implementation, particularly in how it integrates with the Hugging Face Transformers library and utilizes PyTorch and BitsAndBytes for efficient operation.

Overview
Setting Up: First, the script ensures all necessary components are in place, from libraries to the model and dataset.

Database for Activations: A SQLite database is established to track layer activations, providing a clear view into how individual neurons react and which layers are most influential — these are our 'beneficial layers.'

Analyzing and Identifying: By analyzing activation data, the script pinpoints which layers are most valuable to the model's performance.

Configuring DLEC: A configuration is then created, guiding how the model should incorporate duplicates of these beneficial layers to boost effectiveness without unnecessarily increasing complexity.

Reconfiguring and Running the Model: Finally, the model is adjusted according to DLEC's insights, focusing enhancement on the identified layers.

Key Features:
Selective Layer Duplication: DLEC doesn't just add more layers; it doubles down on the ones that really matter. This methodical selection ensures we're making the most of the model's capabilities without wasteful expansion.

Smart Resource Management: By honing in on specific areas for improvement, DLEC aims to make better use of computational and memory resources, promoting more efficient learning without adding undue complexity to the model.

This approach is about making informed, strategic enhancements to model architecture, prioritizing efficiency and effectiveness in utilizing neural network capabilities.

# This Method is still in development and I do not expect "Game Changing" or will I oversell this method, it is purely done for fun. Please let me know how the model works for you.

## 💻 Usage

```python
!pip install -qU transformers accelerate

from transformers import AutoTokenizer
import transformers
import torch

model = "TheSkullery/phi-2-DLEC"
messages = [{"role": "user", "content": "What is a large language model?"}]

tokenizer = AutoTokenizer.from_pretrained(model)
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
pipeline = transformers.pipeline(
    "text-generation",
    model=model,
    torch_dtype=torch.float16,
    device_map="auto",
)

outputs = pipeline(prompt, max_new_tokens=256, do_sample=True, temperature=0.7, top_k=50, top_p=0.95)
print(outputs[0]["generated_text"])
