Solution overview

Overview

The training steps of the model include 2 stages:

• Continue pretraining: Using text corpus collected from external data about elementary school mathematics knowledge, some types of exercises to help LLM align with mathematical knowledge.

• Finetuning: Using the dataset provided by the organizers and some filtered data in the format Question, Choices, Explanation, Answer to train Reasoning for the model from Stage 1.

Finetune

We train the model following instruction with the input being Question + Choices and the output being Explanation + Answer.

The input data is filled with complete explanations to ensure the model always makes inferences before giving an answer.

Inference

Using intfloat/e5-base as embedding model

In the inference phase, we use a few-shot prompting, using an additional embedding model to find the top-k samples that are most similar to the question + input choice. We then post-process and give the final answer.

Data Curation

In this section, we will provide the data sets used and processing directions to create data sets for the two stages of Continue Pretraining and Finetuning.

Data from Competition

This is the original data provided by the contest organizers. We used models such as GPT-3.5, GPT-4 to process the data, as well as create manual data sets for evaluation in development environment. All datasets are placed in datasets/.

All processed datasets:

Dataset Name	Description	Size	Filename	Note
Original Train	training dataset from competition organizer	1200	math_train.json, with explanation: 537	Only a few with explanation
GPT3.5 Generate Explanation	Using GPT3.5 to generate explanation fields	1200	with-missing-explain-3.5.json
GPT4 Generate Explanation	Using GPT4 to generate explanation fields	1200	with-missing-explain-4.json
Public Test	public test dataset from competition organizer	189	math_test.json	Several questions with no answer
Public Test with Hand Label for Local Evaluation	add answer fields to public test dataset	189	math_test_with_hand_label.json
Crawled Hand Label Public Test	Create a similar public test dataset for evaluation	140	validation/convert_collect_data.json
Qualified dataset for Finetune	Combination of Cleaned Original Train Missing Explanation with Generated by GPT-4	1349	qualified_data.json

External Datasets

We rely mainly on crawling online teaching websites for elementary school students and the benchmark dataset is translated into Vietnamese to take advantage of the above two stages.

External datasets:

Vietnamese Elementary Math Knowledge and Workbook	Crawled dataset of text corpus in https://tech12h.com/	10246	https://huggingface.co/datasets/hllj/vi_math_problem_crawl	text corpus about math and problem in books for students.

Continue pretraining Dataset

The dataset will follow the continue pretrain direction with text corpora and training for 1 epoch. All datasets for pretraining are in datasets/pretrain/.

Total		32653

Finetuning Dataset

Finetuning data set is created from the competition dataset plus with external datasets with multiple-choice format, in addition to adding data, we also filter out some erroneous data or missing explanations to increase the model's inference ability. All datasets for finetuning are in datasets/finetune/.

Final Solution

Pretraining

bash run_pt.sh

Finetune with SFTTrainer

using HuggingFaceH4/zephyr-7b-beta as base model

ACCELERATE_LOG_LEVEL=info accelerate launch --config_file <multi_gpu.yaml / deepspeed_zero3.yaml> --num_processes=1 sft.py config_lora.yaml

Example:

ACCELERATE_LOG_LEVEL=info accelerate launch --config_file multi_gpu.yaml --num_processes=1 sft.py config_lora.yaml

Inference

Quantization inference 4bit / 8bit

python inference.py --model_name hllj/zephyr-7b-beta-vi-math --peft_model outputs-sft-zephyr-beta-v1/checkpoint-1500/ --load_in 4bit/8bit --max_new_tokens 512 --temperature 0.1

• model_name: base model using for finetuning
• peft_model: folder contains LoRA finetune output
• load_in: 4bit / 8bit quantization
• max_new_tokens: maximum generating tokens
• temperature: temperature for sampling (we're chosing range from 0.1 to 0.5)

Inference with vLLM

vLLM is faster about (20%~40%) comparing with simple quantization inference.

Merge base model with LoRA

Because when inference with vLLM, it doesn't allow using LoRA outputs but the merged weights itself

python merge_peft_adapter.py --model_type auto --base_model <name or path base model> --tokenizer_path <name or path tokenizer> --lora_model <lora folder> --output_dir <output folder for merged model>

Example:

python merge_peft_adapter.py --model_type auto --base_model hllj/mistral-vi-math --tokenizer_path lora --lora_model lora --output_dir final

Inference

python inference_vllm.py --model_path <output folder for merged model> --max_new_tokens 1024 --temperature 0.1 --output_filepath submission.csv

Example:

python inference_vllm.py --model_path final --max_new_tokens 1024 --temperature 0.1 --output_filepath submission.csv
