LightAutoML (LAMA) is an AutoML framework which provides automatic model creation for the following tasks:
- binary classification
- multiclass  classification
- regression

Current version of the package handles datasets that have independent samples in each row. I.e. **each row is an object with its specific features and target**.
Multitable datasets and sequences are a work in progress :)

**Note**: we use [`AutoWoE`](https://pypi.org/project/autowoe) library to automatically create interpretable models.

**Documentation** of LightAutoML is available [here](https://lightautoml.readthedocs.io/), you can also [generate](https://github.com/AILab-MLTools/LightAutoML/blob/master/.github/CONTRIBUTING.md#building-documentation) it.

# Installation
To install LAMA framework on your machine from PyPI, execute following commands:
```bash

# Install base functionality:

pip install -U lightautoml

# For partial installation use corresponding option.
# Extra dependecies: [nlp, cv, report]
# Or you can use 'all' to install everything

pip install -U lightautoml[nlp]

```

Additionaly, run following commands to enable pdf report generation:

```bash
# MacOS
brew install cairo pango gdk-pixbuf libffi

# Debian / Ubuntu
sudo apt-get install build-essential libcairo2 libpango-1.0-0 libpangocairo-1.0-0 libgdk-pixbuf2.0-0 libffi-dev shared-mime-info

Let's solve the popular Kaggle Titanic competition below. There are two main ways to solve machine learning problems using LightAutoML:
* Use ready preset for tabular data:
```python
import pandas as pd
from sklearn.metrics import f1_score

from lightautoml.automl.presets.tabular_presets import TabularAutoML
from lightautoml.tasks import Task

df_train = pd.read_csv('../input/titanic/train.csv')
df_test = pd.read_csv('../input/titanic/test.csv')

automl = TabularAutoML(
    task = Task(
        name = 'binary',
        metric = lambda y_true, y_pred: f1_score(y_true, (y_pred > 0.5)*1))
)
oof_pred = automl.fit_predict(
    df_train,
    roles = {'target': 'Survived', 'drop': ['PassengerId']}
)
test_pred = automl.predict(df_test)

pd.DataFrame({
    'PassengerId':df_test.PassengerId,
    'Survived': (test_pred.data[:, 0] > 0.5)*1
}).to_csv('submit.csv', index = False)
```

LighAutoML framework has a lot of ready-to-use parts and extensive customization options, to learn more check out the [resources](#Resources) section.

# LightAutoML - automatic model creation framework

LightAutoML (LAMA) is an AutoML framework which provides automatic model creation for the following tasks:
- binary classification
- multiclass  classification
- regression

Current version of the package handles datasets that have independent samples in each row. I.e. **each row is an object with its specific features and target**.
Multitable datasets and sequences are a work in progress :)

**Note**: we use [`AutoWoE`](https://pypi.org/project/autowoe) library to automatically create interpretable models.

**Authors**: [Alexander Ryzhkov](https://kaggle.com/alexryzhkov), [Anton Vakhrushev](https://kaggle.com/btbpanda), [Dmitry Simakov](https://kaggle.com/simakov), Vasilii Bunakov, Rinchin Damdinov, Alexander Kirilin, Pavel Shvets.

**Documentation** of LightAutoML is available [here](https://lightautoml.readthedocs.io/), you can also [generate](https://github.com/AILab-MLTools/LightAutoML/blob/master/.github/CONTRIBUTING.md#building-documentation) it.

# (New features) GPU and Spark pipelines
Full GPU and Spark pipelines for LightAutoML currently available for developers testing (still in progress). The code and tutorials for:
- GPU pipeline is [available here](https://github.com/Rishat-skoltech/LightAutoML_GPU)
- Spark pipeline is [available here](https://github.com/sb-ai-lab/SLAMA)

# Installation
To install LAMA framework on your machine from PyPI, execute following commands:
```bash

# Install base functionality:

pip install -U lightautoml

# For partial installation use corresponding option.
# Extra dependecies: [nlp, cv, report]
# Or you can use 'all' to install everything

pip install -U lightautoml[nlp]

```

Additionaly, run following commands to enable pdf report generation:

```bash
# MacOS
brew install cairo pango gdk-pixbuf libffi

# Debian / Ubuntu
sudo apt-get install build-essential libcairo2 libpango-1.0-0 libpangocairo-1.0-0 libgdk-pixbuf2.0-0 libffi-dev shared-mime-info

# Fedora
sudo yum install redhat-rpm-config libffi-devel cairo pango gdk-pixbuf2

# Windows
# follow this tutorial https://weasyprint.readthedocs.io/en/stable/install.html#windows
```

Let's solve the popular Kaggle Titanic competition below. There are two main ways to solve machine learning problems using LightAutoML:
* Use ready preset for tabular data:
```python
import pandas as pd
from sklearn.metrics import f1_score

from lightautoml.automl.presets.tabular_presets import TabularAutoML
from lightautoml.tasks import Task

df_train = pd.read_csv('../input/titanic/train.csv')
df_test = pd.read_csv('../input/titanic/test.csv')

automl = TabularAutoML(
    task = Task(
        name = 'binary',
        metric = lambda y_true, y_pred: f1_score(y_true, (y_pred > 0.5)*1))
)
oof_pred = automl.fit_predict(
    df_train,
    roles = {'target': 'Survived', 'drop': ['PassengerId']}
)
test_pred = automl.predict(df_test)

pd.DataFrame({
    'PassengerId':df_test.PassengerId,
    'Survived': (test_pred.data[:, 0] > 0.5)*1
}).to_csv('submit.csv', index = False)
```

LighAutoML framework has a lot of ready-to-use parts and extensive customization options, to learn more check out the [resources](#Resources) section.

**Note 1**: for production you have no need to use profiler (which increase work time and memory consomption), so please do not turn it on - it is in off state by default

**Note 2**: to take a look at this report after the run, please comment last line of demo with report deletion command.
