The emergence of 5G networks will allow cloud computing providers to offer more convenient services. However, security and privacy issues of cloud services in 5G networks represent huge challenges. Recently, to improve security and privacy, …

Understanding Credibility of Adversarial Examples against Smart Grid

2021

Stability assessment is an important task for maintaining reliable operations of power grids. With increased system complexity, deep learning-based stability assessment approaches are promising to address the shortfalls of the traditional time-domain simulation-based approaches. However, …

NusaCrowd: Open Source Initiative for Indonesian NLP Resources

2022 · arXiv (Cornell University)

We present NusaCrowd, a collaborative initiative to collect and unify existing resources for Indonesian languages, including opening access to previously non-public resources. Through this initiative, we have brought together 137 datasets and 118 standardized data …

Probabilistic PV Power Forecasting by a Multi-Modal Method using GPT-Agent to Interpret Weather Conditions

2024

Traditionally Photovoltaic (PV) power generation forecasting is based on numeric meteorological vectors to capture weather conditions, which generally misses valuable multimodal information such as those contained in linguistic weather descriptions. In the light of the …

Classifying Relations via Long Short Term Memory Networks along Shortest Dependency Path

2015 · arXiv (Cornell University)

Relation classification is an important research arena in the field of natural language processing (NLP). In this paper, we present SDP-LSTM, a novel neural network to classify the relation of two entities in a sentence. …

Natural Language Inference by Tree-Based Convolution and Heuristic Matching

2016

In this paper, we propose the TBCNNpair model to recognize entailment and contradiction between two sentences. In our model, a tree-based convolutional neural network (TBCNN) captures sentencelevel semantics; then heuristic matching layers like concatenation, element-wise …

Survey of Hallucination in Natural Language Generation

2022 · ACM Computing Surveys

Natural Language Generation (NLG) has improved exponentially in recent years thanks to the development of sequence-to-sequence deep learning technologies such as Transformer-based language models. This advancement has led to more fluent and coherent NLG, leading …

A Multitask, Multilingual, Multimodal Evaluation of ChatGPT on Reasoning, Hallucination, and Interactivity

2023 · arXiv (Cornell University)

This paper proposes a framework for quantitatively evaluating interactive LLMs such as ChatGPT using publicly available data sets. We carry out an extensive technical evaluation of ChatGPT using 23 data sets covering 8 different common …
