cesnet-tszoo 0.1.0

A toolkit for working with large time series network traffic datasets.

The goal of cesnet-tszoo project is to provide time series datasets with useful tools for preprocessing and reproducibility. Such as:

• API for downloading, configuring and loading CESNET-TimeSeries24, CESNET-AGG23 datasets. Each with various sources and aggregations.
• Example of configuration options:
  • Data can be split into train/val/test sets. Split can be done by time series or by time periods.
  • Transforming of data with built-in scalers or with custom scalers.
  • Handling missing values built-in fillers or with custom fillers.
• Creation and import of benchmarks, for easy reproducibility of experiments.
• Creation and import of annotations. Can create annotations for specific time series, specific time or specific time in specific time series.

Examples

Initialize dataset to create train, validation, and test dataframes

Using TimeBasedCesnetDataset dataset

from cesnet_tszoo.datasets import CESNET_TimeSeries24
from cesnet_tszoo.utils.enums import SourceType, AgreggationType
from cesnet_tszoo.configs import TimeBasedConfig

dataset = CESNET_TimeSeries24.get_dataset(data_root="/some_directory/", source_type=SourceType.INSTITUTIONS, aggregation=AgreggationType.AGG_1_DAY, is_series_based=False)
config = TimeBasedConfig(
    ts_ids=50, # number of randomly selected time series from dataset
    train_time_period=range(0, 100), 
    val_time_period=range(100, 150), 
    test_time_period=range(150, 250), 
    features_to_take=["n_flows", "n_packets"])
dataset.set_dataset_config_and_initialize(config)

train_dataframe = dataset.get_train_df()
val_dataframe = dataset.get_val_df()
test_dataframe = dataset.get_test_df()

Time-based datasets are configured with TimeBasedConfig.

Using SeriesBasedCesnetDataset dataset

from cesnet_tszoo.datasets import CESNET_TimeSeries24
from cesnet_tszoo.utils.enums import SourceType, AgreggationType
from cesnet_tszoo.configs import SeriesBasedConfig

dataset = CESNET_TimeSeries24.get_dataset(data_root="/some_directory/", source_type=SourceType.INSTITUTIONS, aggregation=AgreggationType.AGG_1_DAY, is_series_based=True)
config = SeriesBasedConfig(
    time_period=range(0, 250), 
    train_ts=100, # number of randomly selected time series from dataset
    val_ts=30, # number of randomly selected time series from dataset
    test_ts=20, # number of randomly selected time series from dataset
    features_to_take=["n_flows", "n_packets"])
dataset.set_dataset_config_and_initialize(config)

train_dataframe = dataset.get_train_df()
val_dataframe = dataset.get_val_df()
test_dataframe = dataset.get_test_df()

Series-based datasets are configured with SeriesBasedConfig.

Using load_benchmark

from cesnet_tszoo.benchmarks import load_benchmark

benchmark = load_benchmark(identifier="2e92831cb502", data_root="/some_directory/")
dataset = benchmark.get_initialized_dataset()

train_dataframe = dataset.get_train_df()
val_dataframe = dataset.get_val_df()
test_dataframe = dataset.get_test_df()

Whether loaded dataset is series-based or time-based depends on the benchmark. What can be loaded corresponds to previous datasets.
