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])
