The name altility stands for 'actively learning utility', and was first developed
to help electric utilities in the process of placing new smart meters in space and
collecting their data at different times. This package, however, can now be used
and be further developed for any type of spatio-temporal prediction task.
### Installation:
```
pip install altility
```
### Docker:
For using altility within an Ubuntu docker container
```
docker run -it aryandoustarsam/altility
```
For using altility with Jupyter notebook inside a docker container
```
docker run -it -p 3333:1111 -v ~/path_to_data/data:/data aryandoustarsam/altility:jupyter
[inside running container]: jupyter notebook --ip 0.0.0.0 --port 1111 --no-browser --allow-root
[in local machine browser]: localhost:3333
[in local machine browser, type token shown in terminal]
```
### Usage guide:
At the core of the altility package stands the class **altility.ADL_model**. It
bundles properties and methods of the active deep learning (ADL) model that we
want to train. Bellow is a list of all parameters it takes when initialized, methods
it contains and results it can generate.

picked_array = np.zeros([len(y_cand),], dtype=bool)
picked_array[ADL_model.batch_index_list] = True
pred_array = np.invert(picked_array)
### Extract selected data from candidate data pool for training
y_picked = y_cand[picked_array]
x_t_picked = x_t_cand[picked_array]
x_s_picked = x_s_cand[picked_array]
### Train model with picked data
ADL_model.train(
y_picked,
x_t_picked,
x_s_picked,
silent=False,
plot=True
)
### Extract not selected data from candidate data pool for testing/predicting
y_pred = y_cand[pred_array]
x_t_pred = x_t_cand[pred_array]
x_s_pred = x_s_cand[pred_array]
### Predict on remaining data
ADL_model.predict(
y_pred,
x_t_pred,
x_s_pred,
silent=False,
plot=True
)
