Neuro-Symbolic Regex Synthesis Framework via Neural Example Splitting

no code implementations20 May 2022 Su-Hyeon Kim, Hyunjoon Cheon, Yo-Sub Han, Sang-Ki Ko

We tackle the problem of learning regexes faster from positive and negative strings by relying on a novel approach called `neural example splitting'.

SplitRegex: Faster Regex Synthesis via Neural Example Splitting

no code implementations29 Sep 2021 Su-Hyeon Kim, Hyunjoon Cheon, Yo-Sub Han, Sang-Ki Ko

SplitRegex is a divided-and-conquer framework for learning target regexes; split (=divide) positive strings and infer partial regexes for multiple parts, which is much more accurate than the whole string inferring, and concatenate (=conquer) inferred regexes while satisfying negative strings.

6MapNet: Representing soccer players from tracking data by a triplet network

no code implementations10 Sep 2021 Hyunsung Kim, Jihun Kim, Dongwook Chung, Jonghyun Lee, Jinsung Yoon, Sang-Ki Ko

Although the values of individual soccer players have become astronomical, subjective judgments still play a big part in the player analysis.

SoftRegex: Generating Regex from Natural Language Descriptions using Softened Regex Equivalence

no code implementations IJCNLP 2019 Jun-U Park, Sang-Ki Ko, Marco Cognetta, Yo-Sub Han

We continue the study of generating se-mantically correct regular expressions from natural language descriptions (NL).

Neural Sign Language Translation based on Human Keypoint Estimation

no code implementations28 Nov 2018 Sang-Ki Ko, Chang Jo Kim, Hyedong Jung, Choongsang Cho

Using the KETI sign language dataset, we develop a neural network model for translating sign videos into natural language sentences by utilizing the human keypoints extracted from a face, hands, and body parts.
