Devil’s Advocate: Novel Boosting Ensemble Method from Psychological Findings for Text Classification

1 code implementation Findings (EMNLP) 2021 Hwiyeol Jo, Jaeseo Lim, Byoung-Tak Zhang

We present a new form of ensemble method–Devil’s Advocate, which uses a deliberately dissenting model to force other submodels within the ensemble to better collaborate.

Taxonomy and Analysis of Sensitive User Queries in Generative AI Search

no code implementations5 Apr 2024 Hwiyeol Jo, Taiwoo Park, Nayoung Choi, Changbong Kim, Ohjoon Kwon, Donghyeon Jeon, Hyunwoo Lee, Eui-Hyeon Lee, Kyoungho Shin, Sun Suk Lim, Kyungmi Kim, Jihye Lee, Sun Kim

Although there has been a growing interest among industries to integrate generative LLMs into their services, limited experiences and scarcity of resources acts as a barrier in launching and servicing large-scale LLM-based conversational services.

Ground-Truth Labels Matter: A Deeper Look into Input-Label Demonstrations

no code implementations25 May 2022 Kang Min Yoo, Junyeob Kim, Hyuhng Joon Kim, Hyunsoo Cho, Hwiyeol Jo, Sang-Woo Lee, Sang-goo Lee, Taeuk Kim

Despite recent explosion of interests in in-context learning, the underlying mechanism and the precise impact of the quality of demonstrations remain elusive.

Ruminating Word Representations with Random Noise Masking

no code implementations1 Jan 2021 Hwiyeol Jo, Byoung-Tak Zhang

Through the re-training process, some of noises can be compensated and other noises can be utilized to learn better representations.

Human-Like Active Learning: Machines Simulating the Human Learning Process

no code implementations7 Nov 2020 Jaeseo Lim, Hwiyeol Jo, Byoung-Tak Zhang, Jooyong Park

In the end, we showed not only that we can make build better machine training framework through the human experiment result, but also empirically confirm the result of human experiment through imitated machine experiments; human-like active learning have crucial effect on learning performance.

Ruminating Word Representations with Random Noised Masker

no code implementations8 Nov 2019 Hwiyeol Jo, Byoung-Tak Zhang

Next, we gradually add random noises to the word representations and repeat the training process from scratch, but initialize with the noised word representations.

Expansional Retrofitting for Word Vector Enrichment

no code implementations22 Aug 2018 Hwiyeol Jo

Retrofitting techniques, which inject external resources into word representations, have compensated the weakness of distributed representations in semantic and relational knowledge between words.

Psychological State in Text: A Limitation of Sentiment Analysis

no code implementations3 Jun 2018 Hwiyeol Jo, Jeong Ryu

Starting with the idea that sentiment analysis models should be able to predict not only positive or negative but also other psychological states of a person, we implement a sentiment analysis model to investigate the relationship between the model and emotional state.

Extrofitting: Enriching Word Representation and its Vector Space with Semantic Lexicons

2 code implementations WS 2018 Hwiyeol Jo, Stanley Jungkyu Choi

The method consists of 3 steps as follows: (i) Expanding 1 or more dimension(s) on all the word vectors, filling with their representative value.

What we really want to find by Sentiment Analysis: The Relationship between Computational Models and Psychological State

no code implementations11 Apr 2017 Hwiyeol Jo, Soo-Min Kim, Jeong Ryu

As the first step to model emotional state of a person, we build sentiment analysis models with existing deep neural network algorithms and compare the models with psychological measurements to enlighten the relationship.

Re-presenting a Story by Emotional Factors using Sentimental Analysis Method

no code implementations13 Jul 2016 Hwiyeol Jo, Yohan Moon, Jong In Kim, Jeong Ryu

The results of CES-D and PANAS show the relationship between emotion and memory retrieval as follows: depressed people have shown a tendency of representing a story more negatively, and they seemed less expressive.
