How does BERT process disfluency?

no code implementations SIGDIAL (ACL) 2021 Ye Tian, Tim Nieradzik, Sepehr Jalali, Da-Shan Shiu

Analysis on sentence embeddings of disfluent and fluent sentence pairs reveals that the deeper the layer, the more similar their representation (exp2).

Breeze-7B Technical Report

no code implementations5 Mar 2024 Chan-Jan Hsu, Chang-Le Liu, Feng-Ting Liao, Po-chun Hsu, Yi-Chang Chen, Da-Shan Shiu

Breeze-7B is an open-source language model based on Mistral-7B, designed to address the need for improved language comprehension and chatbot-oriented capabilities in Traditional Chinese.

Advancing the Evaluation of Traditional Chinese Language Models: Towards a Comprehensive Benchmark Suite

1 code implementation15 Sep 2023 Chan-Jan Hsu, Chang-Le Liu, Feng-Ting Liao, Po-chun Hsu, Yi-Chang Chen, Da-Shan Shiu

In an effort to advance the evaluation of language models in Traditional Chinese and stimulate further research in this field, we have open-sourced our benchmark and opened the model for trial.

Generative Diffusion Models for Radio Wireless Channel Modelling and Sampling

no code implementations10 Aug 2023 Ushnish Sengupta, Chinkuo Jao, Alberto Bernacchia, Sattar Vakili, Da-Shan Shiu

In this paper, we propose a diffusion model based channel sampling approach for rapidly synthesizing channel realizations from limited data.

Zero-shot Domain-sensitive Speech Recognition with Prompt-conditioning Fine-tuning

1 code implementation18 Jul 2023 Feng-Ting Liao, Yung-Chieh Chan, Yi-Chang Chen, Chan-Jan Hsu, Da-Shan Shiu

In this work, we propose a method to create domain-sensitive speech recognition models that utilize textual domain information by conditioning its generation on a given text prompt.

Image generation with shortest path diffusion

1 code implementation1 Jun 2023 Ayan Das, Stathi Fotiadis, Anil Batra, Farhang Nabiei, FengTing Liao, Sattar Vakili, Da-Shan Shiu, Alberto Bernacchia

We compute the shortest path according to this metric, and we show that it corresponds to a combination of image sharpening, rather than blurring, and noise deblurring.

Improved Convergence Rates for Sparse Approximation Methods in Kernel-Based Learning

no code implementations8 Feb 2022 Sattar Vakili, Jonathan Scarlett, Da-Shan Shiu, Alberto Bernacchia

Kernel-based models such as kernel ridge regression and Gaussian processes are ubiquitous in machine learning applications for regression and optimization.

Uniform Generalization Bounds for Overparameterized Neural Networks

no code implementations13 Sep 2021 Sattar Vakili, Michael Bromberg, Jezabel Garcia, Da-Shan Shiu, Alberto Bernacchia

As a byproduct of our results, we show the equivalence between the RKHS corresponding to the NT kernel and its counterpart corresponding to the Mat\'ern family of kernels, showing the NT kernels induce a very general class of models.

Optimal Order Simple Regret for Gaussian Process Bandits

no code implementations NeurIPS 2021 Sattar Vakili, Nacime Bouziani, Sepehr Jalali, Alberto Bernacchia, Da-Shan Shiu

Consider the sequential optimization of a continuous, possibly non-convex, and expensive to evaluate objective function $f$.

Towards a Universal NLG for Dialogue Systems and Simulators with Future Bridging

no code implementations21 May 2021 Philipp Ennen, Yen-Ting Lin, Ali Girayhan Ozbay, Ferdinando Insalata, Maolin Li, Ye Tian, Sepehr Jalali, Da-Shan Shiu

In light of the recent success of data-driven approaches, we propose the novel future bridging NLG (FBNLG) concept for dialogue systems and simulators.

How to distribute data across tasks for meta-learning?

no code implementations15 Mar 2021 Alexandru Cioba, Michael Bromberg, Qian Wang, Ritwik Niyogi, Georgios Batzolis, Jezabel Garcia, Da-Shan Shiu, Alberto Bernacchia

We show that: 1) If tasks are homogeneous, there is a uniform optimal allocation, whereby all tasks get the same amount of data; 2) At fixed budget, there is a trade-off between number of tasks and number of data points per task, with a unique solution for the optimum; 3) When trained separately, harder task should get more data, at the cost of a smaller number of tasks; 4) When training on a mixture of easy and hard tasks, more data should be allocated to easy tasks.

Model agnostic meta-learning on trees

no code implementations1 Jan 2021 Jezabel Garcia, Federica Freddi, Jamie McGowan, Tim Nieradzik, Da-Shan Shiu, Ye Tian, Alberto Bernacchia

In meta-learning, the knowledge learned from previous tasks is transferred to new ones, but this transfer only works if tasks are related, and sharing information between unrelated tasks might hurt performance.

Meta-Learning

Optimal allocation of data across training tasks in meta-learning

no code implementations1 Jan 2021 Georgios Batzolis, Alberto Bernacchia, Da-Shan Shiu, Michael Bromberg, Alexandru Cioba

They are tested on benchmarks with a fixed number of data-points for each training task, and this number is usually arbitrary, for example, 5 instances per class in few-shot classification.

Cyclic orthogonal convolutions for long-range integration of features

no code implementations NeurIPS Workshop SVRHM 2021 Federica Freddi, Jezabel R Garcia, Michael Bromberg, Sepehr Jalali, Da-Shan Shiu, Alvin Chua, Alberto Bernacchia

We propose a novel architecture that allows flexible information flow between features $z$ and locations $(x, y)$ across the entire image with a small number of layers.
