Refined Continuous Control of DDPG Actors via Parametrised Activation

no code implementations4 Jun 2020 Mohammed Hossny, Julie Iskander, Mohammed Attia, Khaled Saleh

In this paper, we propose enhancing actor-critic reinforcement learning agents by parameterising the final actor layer which produces the actions in order to accommodate the behaviour discrepancy of different actuators, under different load conditions during interaction with the environment.

POS Tagging for Improving Code-Switching Identification in Arabic

no code implementations WS 2019 Mohammed Attia, Younes Samih, Ali Elkahky, Hamdy Mubarak, Ahmed Abdelali, Kareem Darwish

When speakers code-switch between their native language and a second language or language variant, they follow a syntactic pattern where words and phrases from the embedded language are inserted into the matrix language.

Learning from Relatives: Unified Dialectal Arabic Segmentation

no code implementations CONLL 2017 Younes Samih, Mohamed Eldesouki, Mohammed Attia, Kareem Darwish, Ahmed Abdelali, Hamdy Mubarak, Laura Kallmeyer

Arabic dialects do not just share a common koin{\'e}, but there are shared pan-dialectal linguistic phenomena that allow computational models for dialects to learn from each other.

A Neural Architecture for Dialectal Arabic Segmentation

no code implementations WS 2017 Younes Samih, Mohammed Attia, Mohamed Eldesouki, Ahmed Abdelali, Hamdy Mubarak, Laura Kallmeyer, Kareem Darwish

The automated processing of Arabic Dialects is challenging due to the lack of spelling standards and to the scarcity of annotated data and resources in general.

CogALex-V Shared Task: GHHH - Detecting Semantic Relations via Word Embeddings

no code implementations WS 2016 Mohammed Attia, Suraj Maharjan, Younes Samih, Laura Kallmeyer, Thamar Solorio

The evaluation results of our system on the test set is 88. 1{\%} (79. 0{\%} for TRUE only) f-measure for Task-1 on detecting semantic similarity, and 76. 0{\%} (42. 3{\%} when excluding RANDOM) for Task-2 on identifying finer-grained semantic relations.

Arabic Word Generation and Modelling for Spell Checking

no code implementations LREC 2012 Khaled Shaalan, Mohammed Attia, Pavel Pecina, Younes Samih, Josef van Genabith

Furthermore, from a large list of valid forms and invalid forms we create a character-based tri-gram language model to approximate knowledge about permissible character clusters in Arabic, creating a novel method for detecting spelling errors.
