ABOUT ME

Data Scientist and Machine/deep learning engineer

I have experience in a wide range of classical machine learning and more recent deep learning algorithms and have developed machine learning solutions to problems in multiple domains.

My experience primarily comprises developing models for time series predictions and anomaly detection based on signal processing and machine/deep learning algorithms.

Biomedicine, finance and transportation are the major domains I have worked during my academic and professional career.

I have also worked as a freelance developer with local startups in computer vision and financial domains and have developed production-ready deep learning models. Since august 2017, I am working as a data scientist developing data-driven solutions for our clients including include KT, ETRI, Seoul Metropolitan Govt. amongst others.

Data from individual IoT sensors was pre-processed into a 5-min sampled time series of average travel time for each road. The pre-processed and the road infrastructure data was stored into an SQLite database. Multiple linear and machine learning algorithms were compared for lookahead predictions and it was found that TensorFlow-based Long short-term memroy networks (RNN) yielded the best performance that reduced the prediction error to less than 50% of no prediction.

(As a freelance for a local fashion startup) ~ A convolutional neural network was trained on clothing items as a multiclass classification problem. After training, the middle layer of the CNN was used for feature extraction for the images. CNN features were normalized and feature hashing was used for convenient querying. For a given query image, its features are extracted and hashed. The images with the same hashed representation as that of query image are returned as similar images. (2016.10 ~ 2016.12, implemented in Python and TensorFlow, under NDA)
