logo Unsupervised Domain Adaptation for Time Series Classification

This repository contains the official implementation of the benchmark titled "Deep Unsupervised Domain Adaptation for Time Series Classification: a Benchmark" available on ArXiv.

This work was conducted by the logo team at Ericsson Research in France as part of the open source initiative.

avg rank Average rank diagrams, using accuracy on all tested algorithms and hyperparameter tuning methods. The different colors specify the employed hyperparameter tuning method: green for IWCV, blue for Source Risk and red for Target Risk.

Contributions

We welcome contributions to our benchmark.

For contributing, please follow the contribution.md guide.

Requirements

Make sure you have an env with python==3.10 and run the following:

pip install -r requirements.txt

Run

Make sure you are inside src/, then to run a short pipeline of CoDATS model on har dataset with source=12 and target=16 follow the two commands:

Generate the config with hydra

python3 -m _utils.generate_conf 'stages/preprocess=har' 'stages/train=CoDATS' 'utils.idxExperiment=1' 'stages.tune.tuner_config.address=null' 'stages.tune.ray_config.resume=false' 'stages.tune.ray_config.num_samples=1' 'global.train_time_limit=15' 'global.tune_time_limit=30' '++stages.tune.tuner_config.hyperparam_fixed.device=cpu' 'stages.tune.ray_config.resources_per_trial.gpu=0'

Run the pipeline

bash run.sh

View result

cat output/results/dataset_name\=har/source\=12/target\=16/classifier_name\=CoDATS/metrics.json

Docker

To build the docker image:

docker build -t uda-4-tsc:latest .

To run the docker image:

docker run --name uda-4-tsc --network host --entrypoint bash -idt -v /path/to/cloned/uda-4-tsc:/tmp  uda-4-tsc:latest

Now you have the necessary env to run the code.

Alternatively you can use the already published docker image on docker hub: TODO
