## Python
![Python version](https://img.shields.io/badge/python-2.7%2C%203.5%2C%203.6-blue.svg)

#### Installation

Installation can be done through pip:
```shell
pip install libtlda
```

The pip package installs all dependencies. To ensure that these dependencies that don't mess up your current python environment, you should set up a virtual environment. If you're using [conda](https://conda.io/docs/), this can be taken care of by running:
```
conda env create -f environment.yml
source activate libtlda
```

#### Usage

LibTLDA follows a similar structure as [scikit-learn](http://scikit-learn.org/). There are several classes of classifiers that can be imported through for instance:

```python
from libtlda.iw import ImportanceWeightedClassifier
```

With a data set of labeled source samples `(X,y)` and unlabeled target samples `Z`, the classifier can be called and trained using:

```python
clf = ImportanceWeightedClassifier(iwe='kmm')
clf.fit(X, y, Z)
```

Given a trained classifier, predictions can be made as follows:
```python
predictions = clf.predict(Z)
```

Check the [documentation](https://libtlda.readthedocs.io/en/latest/) for more information on specific classes, methods and functions.

## Matlab
![Matlab version](https://img.shields.io/badge/matlab-R2017a-blue.svg)

#### Installation:

First clone the repository and change directory to matlab:
```shell
git clone https://github.com/wmkouw/libTLDA
cd libTLDA/matlab/
```

In the matlab command window, call the installation script. It downloads all dependencies ([minFunc](https://www.cs.ubc.ca/~schmidtm/Software/minFunc.html), [libsvm](https://www.csie.ntu.edu.tw/~cjlin/libsvm/)) and adds them, along with `libtlda`, to your path:
```MATLAB
install.m
```

#### Usage

There is an example script that can be edited to test the different classifiers:
```MATLAB
example.m
```

Questions, comments and bugs can be submitted in the [issues tracker](https://github.com/wmkouw/libTLDA/issues). Any particular method / algorithm / technique that you feel should be included, can be submitted as an issue as well.
