# Cornac
**Cornac** is a comparative framework for multimodal recommender systems. It focuses on making it **convenient** to work with models leveraging **auxiliary data** (e.g., item descriptive text and image, social network, etc). **Cornac** enables **fast** experiments and **straightforward** implementations of new models. It is **highly compatible** with existing machine learning libraries (e.g., TensorFlow, PyTorch).

## Installation
Currently, we are supporting Python 3. There are several ways to install Cornac:
- **From PyPI (you may need a C++ compiler):**
```bash
pip3 install cornac
```
- **From Anaconda:**
```bash
conda install cornac -c conda-forge
```
- **From the GitHub source (for latest updates):**
```bash
pip3 install Cython numpy scipy
git clone https://github.com/PreferredAI/cornac.git
cd cornac
python3 setup.py install
```
**Note:**
Additional dependencies required by models are listed [here](README.md#Models).
Some algorithm implementations use `OpenMP` to support multi-threading. For Mac OS users, in order to run those algorithms efficiently, you might need to install `gcc` from Homebrew to have an OpenMP compiler:
```bash
brew install gcc | brew link gcc
```
## Getting started: your first Cornac experiment
<p align="center"><i>Flow of an Experiment in Cornac</i></p>
```python
import cornac
from cornac.eval_methods import RatioSplit
from cornac.models import MF, PMF, BPR
from cornac.metrics import MAE, RMSE, Precision, Recall, NDCG, AUC, MAP
# load the built-in MovieLens 100K and split the data based on ratio
ml_100k = cornac.datasets.movielens.load_feedback()
rs = RatioSplit(data=ml_100k, test_size=0.2, rating_threshold=4.0, seed=123)
# initialize models, here we are comparing: Biased MF, PMF, and BPR
models = [
MF(k=10, max_iter=25, learning_rate=0.01, lambda_reg=0.02, use_bias=True, seed=123),
PMF(k=10, max_iter=100, learning_rate=0.001, lambda_reg=0.001, seed=123),
BPR(k=10, max_iter=200, learning_rate=0.001, lambda_reg=0.01, seed=123),
]
# define metrics to evaluate the models
metrics = [MAE(), RMSE(), Precision(k=10), Recall(k=10), NDCG(k=10), AUC(), MAP()]
# put it together in an experiment, voilà!
cornac.Experiment(eval_method=rs, models=models, metrics=metrics, user_based=True).run()
```
**Output:**
| | MAE | RMSE | AUC | MAP | NDCG@10 | Precision@10 | Recall@10 | Train (s) | Test (s) |
| ------------------------ | -----: | -----: | -----: | ------: | ------: | -----------: | --------: | ---------: | -------: |

| [PMF](cornac/models/pmf) | 0.7534 | 0.9138 | 0.7744 | 0.0491 | 0.0617 | 0.0533 | 0.0479 | 2.18 | 1.64 |
| [BPR](cornac/models/bpr) | N/A | N/A | 0.8695 | 0.0753 | 0.0975 | 0.0727 | 0.0891 | 3.74 | 1.49 |
