Utilizing Language Models for Energy Load Forecasting
Energy load forecasting plays a crucial role in optimizing resource
allocation and managing energy consumption in buildings and cities. In this
paper, we propose a novel approach that leverages language models for energy
load forecasting. We employ prompting techniques to convert energy consumption
data into descriptive sentences, enabling fine-tuning of language models. By
adopting an autoregressive generating approach, our proposed method enables
predictions of various horizons of future energy load consumption. Through
extensive experiments on real-world datasets, we demonstrate the effectiveness
and accuracy of our proposed method. Our results indicate that utilizing
language models for energy load forecasting holds promise for enhancing energy
efficiency and facilitating intelligent decision-making in energy systems.Comment: BuildSys 2023 Accepte
Human Mobility Question Answering (Vision Paper)
Question answering (QA) systems have attracted much attention from the
artificial intelligence community as they can learn to answer questions based
on the given knowledge source (e.g., images in visual question answering).
However, the research into question answering systems with human mobility data
remains unexplored. Mining human mobility data is crucial for various
applications such as smart city planning, pandemic management, and personalised
recommendation system. In this paper, we aim to tackle this gap and introduce a
novel task, that is, human mobility question answering (MobQA). The aim of the
task is to let the intelligent system learn from mobility data and answer
related questions. This task presents a new paradigm change in mobility
prediction research and further facilitates the research of human mobility
recommendation systems. To better support this novel research topic, this
vision paper also proposes an initial design of the dataset and a potential
deep learning model framework for the introduced MobQA task. We hope that this
paper will provide novel insights and open new directions in human mobility
research and question answering research
Location Contact Tracing: Penetration, Privacy, Position and Performance
The recent COVID-19 pandemic changed radically the world and how people interact, move and behave. Following a lockdown that was imposed worldwide, although with different timing, Mobile Contact Tracing Apps (MCTA) were proposed to digitally trace contacts between individuals, while releasing gradually mobility constraints mandated to contain the disease spread. A general privacy concern on the use of GPS data shifted the efforts towards distributed applications, which use Bluetooth technology to trace proximity and potential infections. Nonetheless, GPS data would help more health operators to understand where hotbeds are, and to what extent the spread is progressing and at what pace. On top of these premises, in this work we take a closer look at the major pillars of MCTA, namely Penetration, Privacy, Position and Performance. We focus on (i) how the penetration rate affects the ability for a tracing applications to work, (ii) the proposal of a novel method of tracing, which build on the GPS technology, (iii) how the position of infections is beneficial to rapidly reduce the infection, and (iv) the discussion of the effects of such paradigm in different scenarios
MAPLE: Mobile App Prediction Leveraging Large Language model Embeddings
Despite the rapid advancement of mobile applications, predicting app usage
remains a formidable challenge due to intricate user behaviours and
ever-evolving contexts. To address these issues, this paper introduces the
Mobile App Prediction Leveraging Large Language Model Embeddings (MAPLE) model.
This innovative approach utilizes Large Language Models (LLMs) to predict app
usage accurately. Rigorous testing on two public datasets highlights MAPLE's
capability to decipher intricate patterns and comprehend user contexts. These
robust results confirm MAPLE's versatility and resilience across various
scenarios. While its primary design caters to app prediction, the outcomes also
emphasize the broader applicability of LLMs in different domains. Through this
research, we emphasize the potential of LLMs in app usage prediction and
suggest their transformative capacity in modelling human behaviours across
diverse fields
