Currently I’m having a career break. Before that, I was an AI/ML Engineer at MediaTek, Taiwan.

I am …

• An AI/ML Engineer who enjoys bringing AI to reality and making it reliable and helpful.
• A ceramics enthusiasts who loves the feeling of creating things by hand. (My ceramics brand: Lean Out Pottery Studio
• An avid reader, espically enjoying contemporary, literary fiction, and other fiction genres. I run an Instagram page to document what I’ve read: 書癡安娜的不完美生活
• A Korean learner. 저는 한국어를 배우고 있어요. 저는 K-드라마를 아주 춯아해요.
• A socialized INFJ. I am emotionally rich but know how to coexist with my emotions. I recharge through solitude, yet I am also good at interacting with others.

We collected a dataset called “EMOPIA”, which is a shared multi-modal (audio and MIDI) database focusing on perceived emotion in pop piano music, to facilitate research on various tasks related to music emotion. I also made an attempt to control the emotion of the generated piano music generated by Transformer using this dataset.

In this paper, I use two transfer learning methods to improve the performance of a VAE-based music generation model given the limited training data. Both the objective and subjective test shows that the two methods indeed improve the performace.

In this work, we try to use the VQ-VAE as feature extractor and two kinds of classifier to automatically classify the genre, theme, or mood of a given audio song. The dataset given by the host is quiet noisy and so we decide not to move forward on this task, but still it’s an interesting experience.

Mini Projects

Code
In the beginning of my ML journey, I start by translating MidiNet from TensorFlow to PyTorch. MidiNet is an well-known GAN-based framework in music automatic generaion field. This project currently has 40 stars on GitHub.

Code
This is a small project I’ve done when I’m taking the course “Artificial intelligence” @ NTU. I use X-ray as input to predict covid19. In this work, I try to use focal loss to deal with data imbalance.

Report
This is the final project I’ve done for the course “Introduction to Intelligent Vehicles” @ NTU. This project got the “Top 20% (~20 ppl) reports” award from the Instrucor!
A context-aware music recommendation system (CARS) means to recommend music based on the environmental factors such as the driver’s mood, the weather condition, or the traffic conditions. On the other hand, in some research, they use music to regularize the driver’s emotions, making driving safer. Especially, the tempo of the music is a common feature to do that. So I try to use the tempo information of the music as an additional feature for the CARS, and the result shows that the tempo information can improve the accuracy of the CARS.
