    MBTI personality classification using Apache Spark
    (ResearchGate, 2021) Orynbekova K.; Talasbek A.; Omar A.
    Personality determines how person make decisions, speak or react on different situations. In this paper explained shortly the specifics of Myers-Briggs Type Indicator personality classification, then details of preparation of the experiment to run on Apache Spark platform. In experiment three different classification algorithms (Logistic Regression, Naive Bayes, Support Vector Machine) are used to train and predict MBTI personality pairs on a Kaggle dataset consisting of 8675 users tweets. In the end explained the data preprocessing and algorithm training, testing, validation details and results. The models with different vector combinations have been compared, and results have been described.

    Pronounciation analysis and mispronounciation detection
    (2022) Omar A.
    We are interested in developing software that can automatically recognize particular phone segments that a non-native student of a foreign language has pronounced incorrectly. A language training system can provide the student with feedback about individual pronunciation errors by using the information about the phone level. For this purpose, in this work, I am trying to develop a transformer model that will recognize spell errors in speech. There were two strategies that were examined: the first one on the original audio dataset, and the second one on the synthetically augmented dataset. Both experiments were compared in this work.
