--- library_name: tf-keras tags: - timeseries --- # Timeseries classification from scratch Based on the _Timeseries classification from scratch_ example on [keras.io](https://keras.io/examples/timeseries/timeseries_classification_from_scratch/) created by [hfawaz](https://github.com/hfawaz/). ## Model description The model is a Fully Convolutional Neural Network originally proposed in [this paper](https://arxiv.org/abs/1611.06455). The implementation is based on the TF 2 version provided [here](https://github.com/hfawaz/dl-4-tsc/). The hyperparameters (kernel_size, filters, the usage of BatchNorm) were found via random search using [KerasTuner](https://github.com/keras-team/keras-tuner). ## Intended uses & limitations Given a time series of 500 samples, the goal is to automatically detect the presence of a specific issue with the engine. The data used to train the model was already _z-normalized_: each timeseries sample has a mean equal to zero and a standard deviation equal to one. ## Training and evaluation data The dataset used here is called [FordA](http://www.j-wichard.de/publications/FordPaper.pdf). The data comes from the [UCR archive](https://www.cs.ucr.edu/%7Eeamonn/time_series_data_2018/). The dataset contains: - 3601 training instances - 1320 testing instances Each timeseries corresponds to a measurement of engine noise captured by a motor sensor. ## Training procedure ### Training hyperparameters The following hyperparameters were used during training: | name | learning_rate | decay | beta_1 | beta_2 | epsilon | amsgrad | training_precision | |----|-------------|-----|------|------|-------|-------|------------------| |Adam|9.999999747378752e-05|0.0|0.8999999761581421|0.9990000128746033|1e-07|False|float32| ## Model Plot
