Improved analysis of randomized SVD for top-eigenvector approximation

no code implementations16 Feb 2022 Ruo-Chun Tzeng, Po-An Wang, Florian Adriaens, Aristides Gionis, Chi-Jen Lu

We present a novel analysis of the randomized SVD algorithm of \citet{halko2011finding} and derive tight bounds in many cases of interest.

Rethinking Why Intermediate-Task Fine-Tuning Works

1 code implementation Findings (EMNLP) 2021 Ting-Yun Chang, Chi-Jen Lu

Supplementary Training on Intermediate Labeled-data Tasks (STILTs) is a widely applied technique, which first fine-tunes the pretrained language models on an intermediate task before on the target task of interest.

TinyGAN: Distilling BigGAN for Conditional Image Generation

1 code implementation29 Sep 2020 Ting-Yun Chang, Chi-Jen Lu

Generative Adversarial Networks (GANs) have become a powerful approach for generative image modeling.

Multiple Text Style Transfer by using Word-level Conditional Generative Adversarial Network with Two-Phase Training

no code implementations IJCNLP 2019 Chih-Te Lai, Yi-Te Hong, Hong-You Chen, Chi-Jen Lu, Shou-De Lin

The objective of non-parallel text style transfer, or controllable text generation, is to alter specific attributes (e. g. sentiment, mood, tense, politeness, etc) of a given text while preserving its remaining attributes and content.

On the Algorithmic Power of Spiking Neural Networks

no code implementations28 Mar 2018 Chi-Ning Chou, Kai-Min Chung, Chi-Jen Lu

Our main technical insight is a dual view of the SNN dynamics, under which SNN can be viewed as a new natural primal-dual algorithm for the l1 minimization problem.

Tracking the Best Expert in Non-stationary Stochastic Environments

no code implementations NeurIPS 2016 Chen-Yu Wei, Yi-Te Hong, Chi-Jen Lu

We study the dynamic regret of multi-armed bandit and experts problem in non-stationary stochastic environments.

Tensor Decomposition via Simultaneous Power Iteration

no code implementations ICML 2017 Po-An Wang, Chi-Jen Lu

Tensor decomposition is an important problem with many applications across several disciplines, and a popular approach for this problem is the tensor power method.

Generalized Mirror Descents in Congestion Games

no code implementations25 May 2016 Po-An Chen, Chi-Jen Lu

Are there more cases of natural no-regret dynamics that perform well in suitable classes of games in terms of convergence and quality of outcomes that the dynamics converge to?

Rivalry of Two Families of Algorithms for Memory-Restricted Streaming PCA

no code implementations4 Jun 2015 Chun-Liang Li, Hsuan-Tien Lin, Chi-Jen Lu

In this paper, we analyze the convergence rate of a representative algorithm with decayed learning rate (Oja and Karhunen, 1985) in the first family for the general $k>1$ case.
