+
- Rank (r): 16
|
40 |
+
- Alpha: 16
|
41 |
+
- Target Modules:

### Merger Details
|
51 |
+
|
52 |
+
- Merger Method: Linear interpolation
|
53 |
+
- Merger Weights: Equal weights (0.25) for each adapter
|
54 |
+
- Combined Rank: 16 (maintained from source adapters)
|
55 |
+
|
56 |
+
## Usage
|
57 |
+
|
58 |
+
This merged adapter must be used with the base Llama-3.1-8B-instruct model.
|
59 |
+
|
60 |
+
### Loading the Model
|
61 |
+
|
62 |
+
```python
|
63 |
+
from peft import PeftModel, PeftConfig
|
64 |
+
from transformers import AutoModelForCausalLM, AutoTokenizer
|
65 |
+
|
66 |
+
# Load base model
|
67 |
+
base_model = AutoModelForCausalLM.from_pretrained("meta-llama/Llama-3.1-8B-instruct")
|
68 |
+
tokenizer = AutoTokenizer.from_pretrained("meta-llama/Llama-3.1-8B-instruct")
|
69 |
+
|
70 |
+
# Load merged LoRA adapter
|
71 |
+
model = PeftModel.from_pretrained(base_model, "path_to_merged_adapter")
|
72 |
+
```
|
73 |
+
|
74 |
+
## Limitations and Biases
|
75 |
+
|
76 |
+
- This merged adapter inherits limitations and biases from:
|
77 |
+
- The base Llama-3.1-8B-instruct model
|
78 |
+
- All four source adapters
|
79 |
+
- The merging process may result in:
|
80 |
+
- Potential loss of specialized capabilities from individual adapters
|
81 |
+
- Averaged behavior across different adapter specializations
|
82 |
+
- Possible interference between adapter weights
|
83 |
+
|
84 |
+
## Merging Process
|
85 |
+
|
86 |
+
The adapters were merged using the following approach:
|
87 |
+
1. Linear interpolation of adapter weights
|
88 |
+
2. Equal weighting (0.25) applied to each source adapter
|
89 |
+
3. Preservation of original LoRA rank and architecture
|
90 |
+
|
91 |
+
### Method Used
|
92 |
+
|
93 |
+
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.
|
94 |
+
|
95 |
+
### Step-by-Step Merging Process
|
96 |
+
|
97 |
+
1. Load the base model and initial adapter:
|
98 |
+
```python
|
99 |
+
from peft import PeftModel, PeftConfig
|
100 |
+
from transformers import AutoModelForCausalLM, AutoTokenizer
|
101 |
+
|
102 |
+
MODEL_NAME = "meta-llama/Meta-Llama-3.1-8B-Instruct"
|
103 |
+
model = AutoModelForCausalLM.from_pretrained(MODEL_NAME)
|
104 |
+
tokenizer = AutoTokenizer.from_pretrained(MODEL_NAME)
|
105 |
+
|
106 |
+
# Load first adapter as base
|
107 |
+
peft_model = PeftModel.from_pretrained(model, "llama319", adapter_name="llama319")
|
108 |
+
```
|
109 |
+
|
110 |
+
2. Load additional adapters:
|
111 |
+
```python
|
112 |
+
# Load remaining adapters
|
113 |
+
peft_model.load_adapter("llama320", adapter_name="llama320")
|
114 |
+
peft_model.load_adapter("llama318", adapter_name="llama318")
|
115 |
+
peft_model.load_adapter("llama317", adapter_name="llama317")
|
116 |
+
peft_model.load_adapter("llama313", adapter_name="llama313")
|
117 |
+
peft_model.load_adapter("llama314", adapter_name="llama314")
|
118 |
+
peft_model.load_adapter("llama315", adapter_name="llama315")
|
119 |
+
peft_model.load_adapter("llama316", adapter_name="llama316")
|
120 |
+
```
|
121 |
+
|
122 |
+
3. Configure and execute the merger:
|
123 |
+
```python
|
124 |
+
# Load F32 models (higher precision)
|
125 |
+
peft_model.load_adapter("llama324", adapter_name="llama324")
|
126 |
+
peft_model.load_adapter("llama320", adapter_name="llama320")
|
127 |
+
peft_model.load_adapter("llama318", adapter_name="llama318")
|
128 |
+
peft_model.load_adapter("llama317", adapter_name="llama317")
|
129 |
+
|
130 |
+
# Load BF16 models
|
131 |
+
peft_model.load_adapter("llama316", adapter_name="llama316")
|
132 |
+
peft_model.load_adapter("llama315", adapter_name="llama315")
|
133 |
+
peft_model.load_adapter("llama314", adapter_name="llama314")
|
134 |
+
peft_model.load_adapter("llama313", adapter_name="llama313")
|
135 |
+
|
136 |
+
# Define adapters and weights
|
137 |
+
# F32 models weighted slightly higher due to higher precision
|
138 |
+
f32_adapters = ["llama319", "llama324", "llama320", "llama318", "llama317"]
|
139 |
+
bf16_adapters = ["llama316", "llama315", "llama314", "llama313"]
|
140 |
+
|
141 |
+
adapters = f32_adapters + bf16_adapters
|
142 |
+
weights = [1.2] * len(f32_adapters) + [0.8] * len(bf16_adapters) # Adjusted weights based on precision
|
143 |
+
|
144 |
+
peft_model.add_weighted_adapter(adapters, weights, "merge", combination_type="ties", density=0.2)
|
145 |
+
peft_model.set_adapter("merge")
|
146 |
+
peft_model.save_pretrained("merged")
|
147 |
+
|
148 |
+
```
|
149 |
+
|
150 |
+
### Key Parameters
|
151 |
+
|
152 |
+
- `combination_type="ties"`: Uses the TIES (Task Interference Edge Selection) method for combining adapters
|
153 |
+
- `density=0.2`: Controls the sparsity of the merged weights
|
154 |
+
|
155 |
+
|
156 |
+
### Notes
|
157 |
+
|
158 |
+
- The order of loading adapters may affect the final result
|
159 |
+
- Equal weights were chosen to maintain balanced influence from each adapter
|
160 |
+
- The merged adapter maintains the same architecture and rank as the original adapters
|
161 |
+
- 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.
|
162 |
+
|
163 |
+
|
164 |
+
## Datasets
|
165 |
+
|
166 |
+
- Not yet released, but should be released after evaluation has completed.
|
167 |
+
- Creating dataset alone tooks more than 3 month for creating 30k pairs dataset.
|
168 |
+
- Only 1k pairs example considered to be synthetic dataset, the rest half synthetic and human written text.
|
169 |
+
|
170 |
+
### Use Cases
|
171 |
+
|
172 |
+
- This merged adapter can be used for a wide range of tasks, including but not limited to:
|
173 |
+
- Accessibility
|
174 |
+
- Revision & Editing
|
175 |
+
- instruction-following use with xml tags
|
176 |
+
- Thinking & reasoning with xml tag of <thinking> and </thinking>, if being asked i the instructions.
|
177 |
+
|
178 |
+
|
179 |
+
These Models not optimized for code, math, or other specialized tasks that need Perefence Optimization.
|
180 |
+
|
181 |
+
## Why SFT Instead of RLHF/DPO?
|
182 |
+
- RLHF and DPO approaches often lead to vocabulary limitations and overfitting due to their optimization objectives
|
183 |
+
|
184 |
+
|
185 |
+
## Why Multiple Adapters?
|
186 |
+
- Resource Issue: Placing the training into smaller adapters requires less GPU memory and compute time while gives more control over the training process.
|
187 |
+
- Iterative Development: Each adapter can be developed and tested independently
|
188 |
+
- Training Infrastructure: The complete fine-tuning process was conducted across multiple sessions, totaling over 100 hours on high-end GPUs (H100, H200, or L40s)
|
189 |
+
- Flexibility: Multiple adapters allow for different combinations or weightings
