On the Trustworthiness of Tree Ensemble Explainability Methods

no code implementations30 Sep 2021 Angeline Yasodhara, Azin Asgarian, Diego Huang, Parinaz Sobhani

The recent increase in the deployment of machine learning models in critical domains such as healthcare, criminal justice, and finance has highlighted the need for trustworthy methods that can explain these models to stakeholders.

Shrinking Bigfoot: Reducing wav2vec 2.0 footprint

no code implementations EMNLP (sustainlp) 2021 Zilun Peng, Akshay Budhkar, Ilana Tuil, Jason Levy, Parinaz Sobhani, Raphael Cohen, Jumana Nassour

Using a teacher-student approach, we distilled the knowledge from the original wav2vec 2. 0 model into a student model, which is 2 times faster and 4. 8 times smaller than the original model.

A Hybrid Instance-based Transfer Learning Method

no code implementations3 Dec 2018 Azin Asgarian, Parinaz Sobhani, Ji Chao Zhang, Madalin Mihailescu, Ariel Sibilia, Ahmed Bilal Ashraf, Babak Taati

Transfer learning can help overcome this issue by transferring the knowledge from readily available datasets (source) to a new dataset (target).

Boosting Model Performance through Differentially Private Model Aggregation

no code implementations12 Nov 2018 Sophia Collet, Robert Dadashi, Zahi N. Karam, Chang Liu, Parinaz Sobhani, Yevgeniy Vahlis, Ji Chao Zhang

In this work, two approaches for private model aggregation are proposed that enable the transfer of knowledge from existing models trained on other companies' datasets to a new company with limited labeled data while protecting each client company's underlying individual sensitive information.

A Dataset for Multi-Target Stance Detection

no code implementations EACL 2017 Parinaz Sobhani, Diana Inkpen, Xiaodan Zhu

Current models for stance classification often treat each target independently, but in many applications, there exist natural dependencies among targets, e. g., stance towards two or more politicians in an election or towards several brands of the same product.

Stance and Sentiment in Tweets

no code implementations5 May 2016 Saif M. Mohammad, Parinaz Sobhani, Svetlana Kiritchenko

However, a person may express the same stance towards a target by using negative or positive language.

A Dataset for Detecting Stance in Tweets

no code implementations LREC 2016 Saif Mohammad, Svetlana Kiritchenko, Parinaz Sobhani, Xiaodan Zhu, Colin Cherry

Apart from stance, the tweets are also annotated for whether the target of interest is the target of opinion in the tweet.

Long Short-Term Memory Over Tree Structures

no code implementations16 Mar 2015 Xiaodan Zhu, Parinaz Sobhani, Hongyu Guo

The chain-structured long short-term memory (LSTM) has showed to be effective in a wide range of problems such as speech recognition and machine translation.
