Exploring the Impact of Generative Artificial Intelligence in Education: A Thematic Analysis
Kaushik, Abhishek, Yadav, Sargam, Browne, Andrew, Lillis, David, Williams, David, Donnell, Jack Mc, Grant, Peadar, Kernan, Siobhan Connolly, Sharma, Shubham, Arora, Mansi
The recent advancements in Generative Artificial intelligence (GenAI) technology have been transformative for the field of education. Large Language Models (LLMs) such as ChatGPT and Bard can be leveraged to automate boilerplate tasks, create content for personalised teaching, and handle repetitive tasks to allow more time for creative thinking. However, it is important to develop guidelines, policies, and assessment methods in the education sector to ensure the responsible integration of these tools. In this article, thematic analysis has been performed on seven essays obtained from professionals in the education sector to understand the advantages and pitfalls of using GenAI models such as ChatGPT and Bard in education. Exploratory Data Analysis (EDA) has been performed on the essays to extract further insights from the text. The study found several themes which highlight benefits and drawbacks of GenAI tools, as well as suggestions to overcome these limitations and ensure that students are using these tools in a responsible and ethical manner.
Adaptive Self-Supervised Learning Strategies for Dynamic On-Device LLM Personalization
Mendoza, Rafael, Cruz, Isabella, Liu, Richard, Deshmukh, Aarav, Williams, David, Peng, Jesscia, Iyer, Rohan
Large language models (LLMs) have revolutionized how we interact with technology, but their personalization to individual user preferences remains a significant challenge, particularly in on-device applications. Traditional methods often depend heavily on labeled datasets and can be resource-intensive. To address these issues, we present Adaptive Self-Supervised Learning Strategies (ASLS), which utilizes self-supervised learning techniques to personalize LLMs dynamically. The framework comprises a user profiling layer for collecting interaction data and a neural adaptation layer for real-time model fine-tuning. This innovative approach enables continuous learning from user feedback, allowing the model to generate responses that align closely with user-specific contexts. The adaptive mechanisms of ASLS minimize computational demands and enhance personalization efficiency. Experimental results across various user scenarios illustrate the superior performance of ASLS in boosting user engagement and satisfaction, highlighting its potential to redefine LLMs as highly responsive and context-aware systems on-device.
Doppler-aware Odometry from FMCW Scanning Radar
Rennie, Fraser, Williams, David, Newman, Paul, De Martini, Daniele
Abstract-- This work explores Doppler information from a millimetre-Wave (mm-W) Frequency-Modulated Continuous-Wave (FMCW) scanning radar to make odometry estimation more robust and accurate. Firstly, doppler information is added to the scan masking process to enhance correlative scan matching. Secondly, we train a Neural Network (NN) for regressing forward velocity directly from a single radar scan; we fuse this estimate with the correlative scan matching estimate and show improved robustness to bad estimates caused by challenging environment geometries, e.g. We test our method with a novel custom dataset which is released with this work at https://ori.ox.ac.uk/publications/datasets. Index Terms-- radar odometry, doppler, navigation, dataset As considered deployment scenarios become more challenging, the detection methods and the sensors collecting data about a vehicle's surroundings must Figure 1: Radar scan from the RDD dataset. Currently, the primary sensors used by autonomous two regions extracted show the "zig-zag" pattern caused by vehicles are cameras and LiDAR: while these traditional the alternating modulation patterns - in conjunction with the sensors may perform adequately under favourable conditions, ego-vehicle speed.
On Semi-Supervised Classification
Krishnapuram, Balaji, Williams, David, Xue, Ya, Carin, Lawrence, Figueiredo, Mário, Hartemink, Alexander J.
A graph-based prior is proposed for parametric semi-supervised classification. The prior utilizes both labelled and unlabelled data; it also integrates features from multiple views of a given sample (e.g., multiple sensors), thus implementing a Bayesian form of co-training. An EM algorithm for training the classifier automatically adjusts the tradeoff between the contributions of: (a) the labelled data; (b) the unlabelled data; and (c) the co-training information. Active label query selection is performed using a mutual information based criterion that explicitly uses the unlabelled data and the co-training information. Encouraging results are presented on public benchmarks and on measured data from single and multiple sensors.
