+ Building the architecture of Speech Analytic system that provides information insight the audio data like mentioned entities, topic, keywords and emotions of the speaker.+ Contributing to the Automatic Transcription Solutions `Origin-STT' in text pre-processing and building a dynamic language model for the vast number of speech domains. This product honored in the highest award category in the information technology field at Vietnam Talent Awards 2019. + Post-processing Automatic Speech Recognition (ASR). Building model to re-format the result of ASR (that don’t have punctuation and all lower case character) for readable. The technique using here is chunk merging combine with Transformer model had been benefit for processing effective long sequence and take accurate result. This model is applied in Meeting Transcription System that deployed for Vietnam Congress Office , Vietnam Central Committee Office of the Communist Party, and many provinces office in Vietnam. + Chatbot Framework. The framework is base on Rasa, making it easy to create and train a chatbot. Developer can define actions for chatbot and end user can train chatbot to decide when action should be run by chatting to it. Framework is core and it can integrate with any chat text interface (facebook messenger, skype,..) or voice interface to interact with people.

Chatbot has some functionslike find, order product, check status delivery,...+ Chatbot for E-commerce website like Chongiadung, Adayroi. Chatbot is embedded ontheir Facebook page and acting like customer services, it supports some action like makeorder, check and cancel order,...+ Vietnamese spell correction. Using an end-to-end deep learning model to auto correctVietnamese errors such as misspellings, missing marks, lowercase letters,... This modelusing seq2seq architecture, and training in using 12 million pairs of sentence error mappingwith correct. The result can view in https://ai.botdy.vn+ Image searching. Building a system for searching product images. Using Faster RCNNfor object detection and Inception pre-trained for feature extraction and search in featureextracted.

+ Recommendation system. Galaxy gift is an application of Samsung, that offer promotescode for a user using Samsung mobile. Using some method, for example, content-based,session-base to recommend user some promotes that maybe they like.+ Handwriting Optical Character Recognition. Making a model to do OCR for handwritingtext, using CRNN architecture for image extract features and make correct text using asequence-to-sequence model. This model is got the second prize in Cinammon hackathonwith character error rate is 0.1.+ Text search engine. Making a module using word embedding that can search contentwith semantic, apply for searching promotion code of Samsung Galaxy Gift system+ Big Data analysis. Samsung has two giant factories that produce mobile phone in Vietnam,in Samsung SVMC, I joined build Hadoop system for save log from equipment, do analysiswith Spark in this data to monitor, find out anomaly and improve the performance in theproduction line.
