Multilingual Tourist Assistance using ChatGPT: Comparing Capabilities in Hindi, Telugu, and Kannada

arXiv.org Artificial Intelligence

This research investigates the effectiveness of ChatGPT, an AI language model by OpenAI, in translating English into Hindi, Telugu, and Kannada languages, aimed at assisting tourists in India's linguistically diverse environment. To measure the translation quality, a test set of 50 questions from diverse fields such as general knowledge, food, and travel was used. These were assessed by five volunteers for accuracy and fluency, and the scores were subsequently converted into a BLEU score. The BLEU score evaluates the closeness of a machine-generated translation to a human translation, with a higher score indicating better translation quality. The Hindi translations outperformed others, showcasing superior accuracy and fluency, whereas Telugu translations lagged behind. Human evaluators rated both the accuracy and fluency of translations, offering a comprehensive perspective on the language model's performance.


Testing the Depth of ChatGPT's Comprehension via Cross-Modal Tasks Based on ASCII-Art: GPT3.5's Abilities in Regard to Recognizing and Generating ASCII-Art Are Not Totally Lacking

arXiv.org Artificial Intelligence

Over the eight months since its release, ChatGPT and its underlying model, GPT3.5, have garnered massive attention, due to their potent mix of capability and accessibility. While a niche-industry of papers have emerged examining the scope of capabilities these models possess, the information fed to and extracted from these networks has been either natural language text or stylized, code-like language. Drawing inspiration from the prowess we expect a truly human-level intelligent agent to have across multiple signal modalities, in this work we examine GPT3.5's aptitude for visual tasks, where the inputs feature content provided as ASCII-art without overt distillation into a lingual summary. We conduct experiments analyzing the model's performance on image recognition tasks after various transforms typical in visual settings, trials investigating knowledge of image parts, and tasks covering image generation.


Dialogue Shaping: Empowering Agents through NPC Interaction

arXiv.org Artificial Intelligence

One major challenge in reinforcement learning (RL) is the large amount of steps for the RL agent needs to converge in the training process and learn the optimal policy, especially in text-based game environments where the action space is extensive. However, non-player characters (NPCs) sometimes hold some key information about the game, which can potentially help to train RL agents faster. Thus, this paper explores how to interact and converse with NPC agents to get the key information using large language models (LLMs), as well as incorporate this information to speed up RL agent's training using knowledge graphs (KGs) and Story Shaping.


RT-2: Vision-Language-Action Models Transfer Web Knowledge to Robotic Control

arXiv.org Artificial Intelligence

We study how vision-language models trained on Internet-scale data can be incorporated directly into end-to-end robotic control to boost generalization and enable emergent semantic reasoning. Our goal is to enable a single end-to-end trained model to both learn to map robot observations to actions and enjoy the benefits of large-scale pretraining on language and vision-language data from the web. To this end, we propose to co-fine-tune state-of-the-art vision-language models on both robotic trajectory data and Internet-scale vision-language tasks, such as visual question answering. In contrast to other approaches, we propose a simple, general recipe to achieve this goal: in order to fit both natural language responses and robotic actions into the same format, we express the actions as text tokens and incorporate them directly into the training set of the model in the same way as natural language tokens. We refer to such category of models as vision-language-action models (VLA) and instantiate an example of such a model, which we call RT-2. Our extensive evaluation (6k evaluation trials) shows that our approach leads to performant robotic policies and enables RT-2 to obtain a range of emergent capabilities from Internet-scale training. This includes significantly improved generalization to novel objects, the ability to interpret commands not present in the robot training data (such as placing an object onto a particular number or icon), and the ability to perform rudimentary reasoning in response to user commands (such as picking up the smallest or largest object, or the one closest to another object). We further show that incorporating chain of thought reasoning allows RT-2 to perform multi-stage semantic reasoning, for example figuring out which object to pick up for use as an improvised hammer (a rock), or which type of drink is best suited for someone who is tired (an energy drink).


Summaries, Highlights, and Action items: Design, implementation and evaluation of an LLM-powered meeting recap system

arXiv.org Artificial Intelligence

Meetings play a critical infrastructural role in the coordination of work. In recent years, due to shift to hybrid and remote work, more meetings are moving to online Computer Mediated Spaces. This has led to new problems (e.g. more time spent in less engaging meetings) and new opportunities (e.g. automated transcription/captioning and recap support). Recent advances in large language models (LLMs) for dialog summarization have the potential to improve the experience of meetings by reducing individuals' meeting load and increasing the clarity and alignment of meeting outputs. Despite this potential, they face technological limitation due to long transcripts and inability to capture diverse recap needs based on user's context. To address these gaps, we design, implement and evaluate in-context a meeting recap system. We first conceptualize two salient recap representations -- important highlights, and a structured, hierarchical minutes view. We develop a system to operationalize the representations with dialogue summarization as its building blocks. Finally, we evaluate the effectiveness of the system with seven users in the context of their work meetings. Our findings show promise in using LLM-based dialogue summarization for meeting recap and the need for both representations in different contexts. However, we find that LLM-based recap still lacks an understanding of whats personally relevant to participants, can miss important details, and mis-attributions can be detrimental to group dynamics. We identify collaboration opportunities such as a shared recap document that a high quality recap enables. We report on implications for designing AI systems to partner with users to learn and improve from natural interactions to overcome the limitations related to personal relevance and summarization quality.


The Hydra Effect: Emergent Self-repair in Language Model Computations

arXiv.org Artificial Intelligence

Ablation studies are a vital tool in our attempts to understand the internal computations of neural networks: by ablating components of a trained network at inference time and studying the downstream effects of these ablations we hope to be able to map the network's computational structure and attribute responsibility among different components. In order to interpret the results of interventions on neural networks we need to understand how network computations respond to the types of interventions we typically perform. A natural expectation is that ablating important components will substantially degrade model performance (Morcos et al., 2018) and may cause cascading failures that break the network. We demonstrate that the situation in large language models (LLMs) is substantially more complex: LLMs exhibit not just redundancy but actively self-repairing computations. When one layer of attention heads is ablated, another later layer appears to take over its function.


Lessons in Reproducibility: Insights from NLP Studies in Materials Science

arXiv.org Artificial Intelligence

Natural Language Processing (NLP), a cornerstone field within artificial intelligence, has been increasingly utilized in the field of materials science literature. Our study conducts a reproducibility analysis of two pioneering works within this domain: "Machine-learned and codified synthesis parameters of oxide materials" by Kim et al., and "Unsupervised word embeddings capture latent knowledge from materials science literature" by Tshitoyan et al. We aim to comprehend these studies from a reproducibility perspective, acknowledging their significant influence on the field of materials informatics, rather than critiquing them. Our study indicates that both papers offered thorough workflows, tidy and well-documented codebases, and clear guidance for model evaluation. This makes it easier to replicate their results successfully and partially reproduce their findings. In doing so, they set commendable standards for future materials science publications to aspire to. However, our analysis also highlights areas for improvement such as to provide access to training data where copyright restrictions permit, more transparency on model architecture and the training process, and specifications of software dependency versions. We also cross-compare the word embedding models between papers, and find that some key differences in reproducibility and cross-compatibility are attributable to design choices outside the bounds of the models themselves. In summary, our study appreciates the benchmark set by these seminal papers while advocating for further enhancements in research reproducibility practices in the field of NLP for materials science. This balance of understanding and continuous improvement will ultimately propel the intersecting domains of NLP and materials science literature into a future of exciting discoveries.


Uncertainty in Natural Language Generation: From Theory to Applications

arXiv.org Artificial Intelligence

Recent advances of powerful Language Models have allowed Natural Language Generation (NLG) to emerge as an important technology that can not only perform traditional tasks like summarisation or translation, but also serve as a natural language interface to a variety of applications. As such, it is crucial that NLG systems are trustworthy and reliable, for example by indicating when they are likely to be wrong; and supporting multiple views, backgrounds and writing styles -- reflecting diverse human sub-populations. In this paper, we argue that a principled treatment of uncertainty can assist in creating systems and evaluation protocols better aligned with these goals. We first present the fundamental theory, frameworks and vocabulary required to represent uncertainty. We then characterise the main sources of uncertainty in NLG from a linguistic perspective, and propose a two-dimensional taxonomy that is more informative and faithful than the popular aleatoric/epistemic dichotomy. Finally, we move from theory to applications and highlight exciting research directions that exploit uncertainty to power decoding, controllable generation, self-assessment, selective answering, active learning and more.


A Critical Review of Large Language Models: Sensitivity, Bias, and the Path Toward Specialized AI

arXiv.org Artificial Intelligence

In the realm of Artificial Intelligence (AI), the rise of Large Language Models (LLMs) such as OpenAI's Generative Pretrained Transformer (GPT) series has introduced unprecedented capabilities in text summarization and classification (Min et al., 2021; Yoo et al., 2021). These AI juggernauts can dissect vast quantities of text, distill key points, and even classify documents with a level of speed and accuracy that leaves human ability far behind (Jiang et al., 2022). While we applaud these advancements, it's imperative to keep a clear perspective on their inner workings, particularly their training data and decision making procedures. The advent of LLMs has undoubtedly revolutionized text analytics, but it has also introduced novel challenges concerning sensitivity and potential biases (Albrecht et al., 2022; Liang et al., 2021). Inherent in the training of these models is their susceptibility to embed the biases present in the training data, a subtle yet pervasive issue that can later be extremely difficult to detect and rectify (Alvi et al., 2019; Zhang & Verma, 2021). It's crucial, therefore, to scrutinize not only the LLMs themselves but also the mechanisms that train them. The broad and diverse nature of subjects that these models deal with, ranging from mundane queries to sensitive matters, necessitates a systematic and rigorous training approach.

arXiv.org Artificial Intelligence

Large Language Models (LLMs) have shown remarkable effectiveness in various generaldomain natural language processing (NLP) tasks. However, their performance in transportation safety domain tasks has been suboptimal, primarily attributed to the requirement for specialized transportation safety expertise in generating accurate responses [1]. To address this challenge, we introduce TrafficSafetyGPT, a novel LLaMA-based model, which has undergone supervised fine-tuning using TrafficSafety-2K dataset which has human labels from government produced guiding books and ChatGPT-generated instruction-output pairs. Keywords: ChatGPT, Natural Language Processing, Deep Learning, Traffic Safety, Large Language Models, Generative Pre-trained Transformers 1. Introduction In the realm of natural language processing (NLP) and large language models, a surge in advancements has unfolded a plethora of potential applications. This rapid development, spearheaded by pre-trained large language models like OpenAI's ChatGPT and its derivatives, has drastically augmented our capabilities in language comprehension, generation, and interactivity. The foundational strength of these models lies in their pre-training on extensive and diverse datasets, empowering them to decipher intricate language patterns and contextual interconnections. Nevertheless, while these pre-trained models exhibit commendable proficiency across an array of tasks, their generic nature could constrain their efficacy in niche applications, such as transportation safety.
