kaggle: otto-Multi-Objective Recommender System

My solution, which was in third place at the end of the competition, is now available to the public.

Solution Overview

Makotu part of this URL for solutions.
https://www.kaggle.com/competitions/otto-recommender-system/discussion/382879

Code

Execute .ipynb and .py in order from 0 to 5 in the code folder.

Estimated execution times are as follows.
preprocessing: about 1 day (especially clustering takes time)
Make features: about 1 day
Training & predict: about 1 day

Data

The data for the main source refers to data from radek.
https://www.kaggle.com/datasets/radek1/otto-full-optimized-memory-footprint
https://www.kaggle.com/datasets/radek1/otto-train-and-test-data-for-local-validation
First put these data into "input/train_test" and "input/train_valid" before executing.

Model

https://www.kaggle.com/datasets/mhyodo/otto-makotu-models

for prediction

To reproduce the inference, take the following steps

1. store the original data in the input folder train_test and train_valid (please read the readme for those folders)
2. run code folder from 0-3 (up to 3_features)
3. store the above trained models in each model in the model folder
4. run prediction.py in 5 of the code folder

for train

1. store the original data in the input folder train_test and train_valid (please read the readme for those folders)
2. run code folder from 0-3 (up to 3_features)
3. run train.py in 4 of the code folder

Environment

GPU memory: 24GB(RTX 3090)
CPU memory: 128GB
The system will work in the following environment.
If you have less than that, it will probably stop working in places, so please adjust the code accordingly.
