Sleep Model -- A Sequence Model for Predicting the Next Sleep Stage

no code implementations17 Feb 2023 Iksoo Choi, Wonyong Sung

As sleep disorders are becoming more prevalent there is an urgent need to classify sleep stages in a less disturbing way. In particular, sleep-stage classification using simple sensors, such as single-channel electroencephalography (EEG), electrooculography (EOG), electromyography (EMG), or electrocardiography (ECG) has gained substantial interest.

Fully Neural Network Based Speech Recognition on Mobile and Embedded Devices

no code implementations NeurIPS 2018 Jinhwan Park, Yoonho Boo, Iksoo Choi, Sungho Shin, Wonyong Sung

The RNN implementation on embedded devices can suffer from excessive DRAM accesses because the parameter size of a neural network usually exceeds that of the cache memory and the parameters are used only once for each time step.

SVD-Softmax: Fast Softmax Approximation on Large Vocabulary Neural Networks

no code implementations NeurIPS 2017 Kyuhong Shim, Minjae Lee, Iksoo Choi, Yoonho Boo, Wonyong Sung

The approximate probability of each word can be estimated with only a small part of the weight matrix by using a few large singular values and the corresponding elements for most of the words.
