University of International Business and Economics Sept. 2013- July. 2017 Bachelor of Portuguese Language(Major) / International Trade(Minor) Course Project

1. Neural network parser with the Penn TreeBank data Dec 2019

● Developed a project in Python to train a neural network parser with Penn TreeBank data.

● Used the encoder-decoder framework and conducted experiments with the various attention mechanisms to observe their effect on the performance of the parser.

● Achieved 93% accuracy on the data set with scaled Luong attention 2. POS tag with Average Perceptron Algorithm Nov 2019

● Developed a project to label sentences with part of speech tags.

● Used perceptron algorithm and average perceptron to train the data and viterbi to decode. Took the bigram along with affixes as features.

● Achieved around 92% accuracy on the data set with affixes 3. Detect the discourse relationship with Convolutional Neural Network Oct 2019

● Developed a Python program that builds a CNN model with the data of Penn Discourse Treebank.

● Preprocessed raw data with Google News word vectors, used tensorflow and keras to build the model.

● Achieved around 74% accuracy on the explicit discourse relations 4. Building Logistic Regression Model for Sentiment Analysis Sept 2019

● Developed a Python program that builds a logistic regression model from scratch using posterior possibility.

● Used the mini-batch stochastic gradient descent to optimize the parameters. Implemented a test round after each epoch using development set data. Smooth the trained model by L2 regularization. 5. Song Lyric Mood Detection Annotation May 2019

● Developed a project to annotate the song lyrics with four types of mood and its intensity level.

● Wrote the Annotation Guidelines, used MAE to annotate data, set the gold standard and used NLTK metrics package to compute the Inter Annotator Agreement.

● First-authored a paper pending submission to a relevant workshop 6. Building Association of Computational Linguistics Corpus Dec 2018

● Collected papers published by the Association of Computational Linguistics in 2018 and developed a Python program that transforms those articles in PDF format into TXT format.

● Achieved adding the data into NLTK as a Corpus.
