ARBML Save

Motivation

As you know machine learning has proven its importance in many fields, like computer vision, NLP, reinforcement learning, adversarial learning, etc .. Unfortunately, there is a little work to make machine learning accessible for Arabic-speaking people.

Goal

Our goal is to enrich the Arabic content by creating open-source projects and open the community eyes on the significance of machine learning. We want to create interactive applications that allow novice Arabs to learn more about machine learning and appreciate its advances.

Challenges

Arabic language has many complicated features compared to other languages. First, Arabic language is written right to left. Second, it contains many letters that cannot be pronounced by most foreigners like ض ، غ ، ح ، خ، ظ. Moreover, Arabic language contains special characters called Diacritics which are special characters that help readers pronounced words correctly. For instance the statement السَّلامُ عَلَيْكُمْ وَرَحْمَةُ اللَّهِ وَبَرَكَاتُهُ containts special characters after most of the letters. The diactrics follow special rules to be given to a certain character. These rules are construct a complete area called النَّحْوُ الْعَرَبِيُّ. Compared to English, the Arabic language words letters are mostly connected اللغة as making them disconnected is difficult to read ا ل ل غ ة. Finally, there as many as half a billion people speaking Arabic which resulted in many dialects in different countires.

Procedure

Our procedure is generalized and can be generalized to many language models not just Arabic. This standrized approach takes part as multiple steps starting from training on colab then porting the models to the web.

Models

Name	Description	Notebook	Demo
Arabic Diacritization	Simple RNN model ported from Shakkala
Arabic2English Translation	seq2seq with Attention

Arabic Sentiment Classification	RNN with Bidirectional layer
Arabic Image Captioning	Encoder-Decoder architecture with attention
Arabic Word Similarity	Embedding layers using cosine similarity
Arabic Digits Classification	Basic RNN model with classification head
Arabic Speech Recognition	Basic signal processing and classification
Arabic Object Detection	SSD Object detection model
Arabic Poems Meter Classification	Bidirectional GRU
Arabic Font Classification	CNN
Arabic Text Detection	Optical Character Recognition (OCR)

Datasets

Tools

To make models easily accessible by contributers, developers and novice users we use two approaches

Google Colab

Google colaboratory is a free service that is offered by Google for research purposes. The interface of a colab notebook is very similar to jupyter notebooks with slight differences. Google offers three hardware accelerators CPU, GPU and TPU for speeding up training. We almost all the time use GPU because it is easier to work with and acheives good results in a reasonable time. Check this great tutorial on medium.

TensorFlow.js

TensorFlow.js is part of the TensorFlow ecosystem that supports training and inference of machine learning models in the browser. Please check these steps if you want to port models to the web:

1. Use keras to train models then save the model as model.save('keras.h5')

2. Install the TensorFlow.js converter using pip install tensorflowjs

3. Use the following script to tensorflowjs_converter --input_format keras keras.h5 model/

4. The model directory will contain the files model.json and weight files same to group1-shard1of1

5. Finally you can load the model using TensorFlow.js

Check this tutorial that I made for the complete procedure.

Website

We developed many models to run directly in the browser. Using TensorFlow.js the models run using the client GPU. Since the webpage is static there is no risk of privacy or security. You can visit the website here . Here is the main intefrace of the website

The added models so far

Poems Generation

English Translation

Words Embedding

Sentiment Classification

Image Captioning

Diactrization

Contribution

Check the CONTRIBUTING.md for a detailed explanantion about how to contribute.

Resources

As a start we will start on Github for hosting the website, models, datasets and other contents. Unfortunately, there is a limitation on the space that will hunt us in the future. Please let us know what you suggest on that matter.
