Merged-Llama-Adapters-317-320

A merged LoRA adapter combining four fine-tuned adapters (317-320) for the Llama-3.1-8B language model.

Model Details

Base Model: meta-llama/Llama-3.1-8B-instruct
Adaptation Method: Merged LoRA

Merger Configuration

Source Adapters

All source adapters share the following configuration:

Rank (r): 16
Alpha: 16
Target Modules:
- q_proj (Query projection)
- k_proj (Key projection)
- v_proj (Value projection)
- o_proj (Output projection)
- up_proj (Upsampling projection)
- down_proj (Downsampling projection)
- gate_proj (Gate projection)

Merger Details

Merger Method: Linear interpolation
Merger Weights: Equal weights (0.25) for each adapter
Combined Rank: 16 (maintained from source adapters)

Usage

This merged adapter must be used with the base Llama-3.1-8B-instruct model.

Limitations and Biases

This merged adapter inherits limitations and biases from:
- The base Llama-3.1-8B-instruct model
- More baises from traning data as most of them were fiction work.
The merging process may result in:
- Potential loss of specialized capabilities from individual adapters
- Averaged behavior across different adapter specializations
- Possible interference between adapter weights

Merging Process

The adapters were merged using the following approach:

Linear interpolation of adapter weights
Equal weighting (0.25) applied to each source adapter
Preservation of original LoRA rank and architecture

Method Used

The adapters were merged using PEFT (Parameter-Efficient Fine-Tuning) library's weighted adapter combination feature. The process combines multiple LoRA adapters using linear interpolation with specified weights.

Key Parameters

combination_type="ties": Uses the TIES (Task Interference Edge Selection) method for combining adapters
density=0.2: Controls the sparsity of the merged weights

Notes

The order of loading adapters may affect the final result
Equal weights were chosen to maintain balanced influence from each adapter
The merged adapter maintains the same architecture and rank as the original adapters
While this adapter merges multiple fine-tunes, each component was developed as part of independent research efforts to explore and language model capabilities as part of R&D process.

Datasets

Not yet released, but should be released after evaluation has completed.
Only 1k pairs example of revision task + => <->

Use Cases

This merged adapter can be used for a wide range of tasks, including but not limited to:
- Accessibility
- Revision & Editing
- instruction-following use with xml tags
- Thinking & reasoning with xml tag of and , if being asked i the instructions.

These Models not optimized for code, math, or other specialized tasks that need Perefence Optimization.

Why SFT Instead of RLHF/DPO?

RLHF and DPO approaches often lead to vocabulary limitations and overfitting due to their optimization objectives
