Experience

  • Reducing Gender Bias in Word-level Language Models with Gender-Equalizing Loss Function
    https://arxiv.org/abs/1905.12801

    This paper proposes a novel method to address gender bias in the neural language models. We introduce a penalty term to the objective function of the language model to penalize the discrimination against gender. This method benefits from being simple, intuitive and can be easily incorporated into any text generation model. The proposed model’s performance was evaluated using multiple fairness metrics as well as perplexity showing that this method, when trained with counterfactual data augmentation, outperforms all existing techniques in the literature.

  • Semi-supervised Image Classification with Low Resource Labelled Data
    https://github.com/muaz-urwa/Semi-Supervised-Image-Classification-with-low-resource-labelled-data

    I attended Yann Lecun's Deep Learning class at NYU last year, and this was my term project from it.

    I was awarded the academic award for the class of 2019 at NYU CUSP. This also gave me the honor to address the esteemed audience at the convocation ceremony as a valedictorian speaker.

  • Fare Evasion Detection using Computer Vision
    https://github.com/muaz-urwa/Fare-Evasion-Detection-using-Computer-Vision

    I proposed and presented a cost-effective automated system to measure (rather than estimate) the fare evasion in New York subways using security camera footage to MTA.

  • Human Steering Behaviors Study using Computer Vision
    https://github.com/muaz-urwa/Analyzing-Steering-Behvaiors-of-Human-Agents-using-Computer-Vision

    We wanted to observe if the steering behaviors described are observed in urban settings. We collected video data from a few urban spaces around metro tech to observe the pedestrian mobility tracks in those spaces and used Computer Vision to perform the analysis.
