Evaluating CLIP: Towards Characterization of Broader Capabilities and Downstream Implications

no code implementations5 Aug 2021 Sandhini Agarwal, Gretchen Krueger, Jack Clark, Alec Radford, Jong Wook Kim, Miles Brundage

Recently, there have been breakthroughs in computer vision ("CV") models that are more generalizable with the advent of models such as CLIP and ALIGN.

Reliability Check via Weight Similarity in Privacy-Preserving Multi-Party Machine Learning

no code implementations14 Jan 2021 Kennedy Edemacu, Beakcheol Jang, Jong Wook Kim

Multi-party machine learning is a paradigm in which multiple participants collaboratively train a machine learning model to achieve a common learning objective without sharing their privately owned data.

Successive Point-of-Interest Recommendation with Local Differential Privacy

no code implementations26 Aug 2019 Jong Seon Kim, Jong Wook Kim, Yon Dohn Chung

A point-of-interest (POI) recommendation system performs an important role in location-based services because it can help people to explore new locations and promote advertisers to launch advertisements at appropriate locations.

Adversarial Learning for Improved Onsets and Frames Music Transcription

no code implementations20 Jun 2019 Jong Wook Kim, Juan Pablo Bello

Automatic music transcription is considered to be one of the hardest problems in music information retrieval, yet recent deep learning approaches have achieved substantial improvements on transcription performance.

Neural Music Synthesis for Flexible Timbre Control

no code implementations1 Nov 2018 Jong Wook Kim, Rachel Bittner, Aparna Kumar, Juan Pablo Bello

The recent success of raw audio waveform synthesis models like WaveNet motivates a new approach for music synthesis, in which the entire process --- creating audio samples from a score and instrument information --- is modeled using generative neural networks.

CREPE: A Convolutional Representation for Pitch Estimation

2 code implementations17 Feb 2018 Jong Wook Kim, Justin Salamon, Peter Li, Juan Pablo Bello

To date, the best performing techniques, such as the pYIN algorithm, are based on a combination of DSP pipelines and heuristics.
