I worked with Prof. Austen Lamacraft on using neural networks for lossless audio compression. We are currently gathering results and writing a paper about our findings.* Learned about digital signal processing and wavelet theory, built a neural network that performs a wavelet transform of an audio signal.* Learned about variational inference and variational autoencoders, combined and implemented them with the WaveNet architecture and bits-back compression.* Obtained compression… Show more I worked with Prof. Austen Lamacraft on using neural networks for lossless audio compression. We are currently gathering results and writing a paper about our findings.* Learned about digital signal processing and wavelet theory, built a neural network that performs a wavelet transform of an audio signal.* Learned about variational inference and variational autoencoders, combined and implemented them with the WaveNet architecture and bits-back compression.* Obtained compression ratios better than prior work.* Used PyTorch to code and train dozens of experiments with varying network structures. Deployed experiments on GPU cluster. Created a 9.3 GB dataset of classical music. Show less

Building on my history of contributions to the Zulip open-source project, I joined Zulip for an internship in my gap year between high school and university. Zulip is an open-source work chat platform, similar to Slack.* Built up the Zulip bot ecosystem from a prototype stage to a developer- and user-friendly ecosystem: For example, added server-side storage accessible by bots, enriched and streamlined bot API, enhanced the web interface for customizing bots, wrote technical documentation… Show more Building on my history of contributions to the Zulip open-source project, I joined Zulip for an internship in my gap year between high school and university. Zulip is an open-source work chat platform, similar to Slack.* Built up the Zulip bot ecosystem from a prototype stage to a developer- and user-friendly ecosystem: For example, added server-side storage accessible by bots, enriched and streamlined bot API, enhanced the web interface for customizing bots, wrote technical documentation for developing and using bots. Mostly work in Python and Javascript.* Worked on the Zulip mobile app in React Native. Refactored core components to normalize the previously highly redundant Redux message database. Prevented impending loss of messages in large organizations due to database size limitations by compressing the whole database on each client’s phone. Annotated large parts of the Javascript code for the Flow type checker. Show less
