Everything Has Context
falcon-ehc-contrived-financial-7b
🤷 Purpose
A finetuned adapter (base model: falcon-7b-instruct) that was engineered for Q/A, context-retrieval trained on dylanalloy/ehc-contrived-financial dataset. Read more on the dataset page to understand a bit about how this repo could be used in future "chain-of-thought" research, and what this model cannot reasonably achieve given the contrived nature of the dataset's context.
🧶 Explain
falcon-7b-instruct base model is high performing for the compute, QLoRA is great, bitsandbytes makes quantization easy, PEFT makes the QLoRA training method easy.
The whole thing can be trained on a single 12GB VRAM NVIDIA card released since 2020 in about 2 hours.
🏋️ Training
Finetuning with QLoRA is heavily documented, but the training here was done using the following parameters:
training_args = TrainingArguments(
per_device_train_batch_size=1
, gradient_accumulation_steps=4
, num_train_epochs=20
, learning_rate=2e-4
, fp16=True
, save_total_limit=3
, logging_steps=13
, output_dir=OUTPUT_DIR
, max_steps=500
, optim="paged_adamw_8bit"
, lr_scheduler_type="cosine"
, warmup_ratio=0.05
)
⌨️ Usage
PEFT is important in this implementation. So is bitsandbytes. If you do not know how to use them, their documentation is excellent.

## your to-do:
## process & chunk the responses from your source of context (usually a vector db) & loop into generating longer pieces until the '[ANSWER]:' is created by this adapter model
## without your intervention, [FOLLOWUP]: and [CONTEXT]: will be hallucinated and will be derived from mostly undesirable model knowledge
## this will not do you much good because it will use base model knowledge to continue its own research
# print("FOLLOWUP: "+answer)
## but this will get you started with a context flow where you can inject information and generate further until an answer is found
print("[FOLLOWUP]: "+answer.split('CONTEXT:')[0])
