We introduces a novel data selection strategy, SelectIT, for LLM instruction tuning, which uses LLM uncertainty to efficiently identify high-quality IT data without requiring additional resources. SelectIT includes three types of self-reflection: token, sentence, and model, which can individually and jointly improve the performance of IT data selection. By applying SelectIT to the Alpaca-GPT4 dataset, we introduce a compact and strong IT dataset, called Selective Alpaca. Different models and domain tasks demonstrate the effectiveness of SelectIT. Our analysis reveals that SelectIT effectively excludes abnormal data and tends to select longer and calculational data.

We introduce a novel IT dataset, Selective Alpaca, by selecting the high-quality IT data from the Alpaca-GPT4 dataset.

SelectIT employs different grain uncertainty of LLMs: token, sentence, and model, which can effectually improve the accuracy of IT data selection.
We use the foundation model itself to rate the IT data based on the uncertainty of various tokens.
python3 self_reflection/token_level.py \
-model-name-or-path models--meta-llama--Llama-2-7b-hf \ # path of LLMs
-rp ./data/rating_prompt.txt \ # path of rating_prompt
-i ./data/alpaca_gpt4.json \ # path of instruction dataset
-o ./data/test.json \ # path of output dataset
-k 5 \ # hyper-parameters
-proportion 0.2 \ # the number of instruction data
-alpha 0.2 \ # hyper-parameters
We use sentence-level uncertainty to improve the rating process by exploiting the effect of different prompts on LLMs.
python3 self_reflection/sentence_level.py \
-model-name-or-path models--meta-llama--Llama-2-7b-hf \
-rp ./data/rating_prompt.txt \
-i ./data/alpaca_gpt4.json \
-o ./data/test.json \
-k 5
-proportion 0.2 \
-alpha 0.2 \
We utilize the uncertainty between different LLMs, enabling a collaborative decision-making process for IT data selection.

-o ./data/test.json \
-k 5

-alpha 0.2 \
We provide two training configuration for different LLMs, which can effectively verify the robustness of SelectIT.
We can utilize the following training configuration to fine tune the LLaMA-2 LLMs. Example usages on 4 A800 by 1 node:
