Fruit Picker Activity Recognition with Wearable Sensors and Machine Learning

no code implementations20 Apr 2023 Joel Janek Dabrowski, Ashfaqur Rahman

For farmers and managers, the knowledge of when a picker bag is emptied is important for managing harvesting bins more effectively to minimise the time the picked fruit is left out in the heat (resulting in reduced shelf life).

A Semi-supervised Approach for Activity Recognition from Indoor Trajectory Data

no code implementations9 Jan 2023 Mashud Rana, Ashfaqur Rahman, Daniel Smith

The increasingly wide usage of location aware sensors has made it possible to collect large volume of trajectory data in diverse application domains.

Activity Recognition Decision Making +1

An operational framework to automatically evaluate the quality of weather observations from third-party stations

no code implementations5 Dec 2022 Quanxi Shao, Ming Li, Joel Janek Dabrowski, Shuvo Bakar, Ashfaqur Rahman, Andrea Powell, Brent Henderson

With increasing number of crowdsourced private automatic weather stations (called TPAWS) established to fill the gap of official network and obtain local weather information for various purposes, the data quality is a major concern in promoting their usage.

Smart Headset, Computer Vision and Machine Learning for Efficient Prawn Farm Management

no code implementations14 Oct 2022 Mingze Xi, Ashfaqur Rahman, Chuong Nguyen, Stuart Arnold, John McCulloch

Understanding the growth and distribution of the prawns is critical for optimising the feed and harvest strategies.

Deep Learning and Statistical Models for Time-Critical Pedestrian Behaviour Prediction

no code implementations26 Feb 2020 Joel Janek Dabrowski, Johan Pieter de Villiers, Ashfaqur Rahman, Conrad Beyers

We show that, though the neural network model achieves an accuracy of 80%, it requires long sequences to achieve this (100 samples or more).

Sequence-to-Sequence Imputation of Missing Sensor Data

no code implementations25 Feb 2020 Joel Janek Dabrowski, Ashfaqur Rahman

Although the sequence-to-sequence (encoder-decoder) model is considered the state-of-the-art in deep learning sequence models, there is little research into using this model for recovering missing sensor data.

ForecastNet: A Time-Variant Deep Feed-Forward Neural Network Architecture for Multi-Step-Ahead Time-Series Forecasting

1 code implementation11 Feb 2020 Joel Janek Dabrowski, Yifan Zhang, Ashfaqur Rahman

Recurrent and convolutional neural networks are the most common architectures used for time series forecasting in deep learning literature.

Efficient Orthogonal Parametrisation of Recurrent Neural Networks Using Householder Reflections

1 code implementation ICML 2017 Zakaria Mhammedi, Andrew Hellicar, Ashfaqur Rahman, James Bailey

Our contributions are as follows; we first show that constraining the transition matrix to be unitary is a special case of an orthogonal constraint.
