Webinar: Machine Learning – adding power to the toolbox

Wednesday 23rd September, 2020, 3-4pm AEST

New computing technologies are seeing artificial intelligence methods expand in usefulness. Machine learning is one of these approaches that is gaining momentum for more and more uses.

Based on pattern recognition and iterative learning it delivers repeatable, reliable, automated services. This might be identifying fish, forecasting environmental conditions, transaction tracking, risk estimation, robotics and marketing, to name just a few applications. It works by running mathematical calculations over large volumes of data and using the result to make a prediction, refining the calculations based on how well the prediction works.

This prediction and refining process is learning and can be done in many different ways. Please join us to hear more about the methods and what’s involved, it may inspire ideas of new ways it can be applied in your industry or research area.

Part 1: ML applied to wave prediction

Presented by: Mathieu Cocho, Carnegie Clean Energy

Carnegie Clean Energy is developing advanced controller for its CETO wave-energy converter, with aim to increase the system’s power capture, and reduce loads in extreme conditions. Most advanced controllers rely heavily on future (predicted) knowledge of the incident wave front. Physics-based estimation of future waves can be prohibitively computationally expensive, however, Machine Learning (ML) is being applied in an increasing number of fields to great effect, with its implementation resulting in improved computational performance across the board.

Carnegie has developed a machine learning-based wave predictor, which has the potential to predict surface elevation up to 30 seconds into the future, in fractions of a second. This presentation will provide insight into the development and performance of this tool, which has direct applications in wave energy, but also in other industries, where knowledge of future wave is critical for safety, reliability and success.

Part 2: Automated visual assessment of benthos using machine learning in aquaculture environmental monitoring

Imagery is a common method used for monitoring the benthic environment around aquaculture sites in Tasmania. Images taken beneath the farms’ infrastructure are scored based on the presence of several indicators that relate to sediment condition. An important indicator is the bacterium Beggiatoa growing under anoxic (low-oxygen) conditions, thus potentially indicating impact. Scoring for Beggiatoa is based on percentage cover on the seafloor. Manually evaluating images is time consuming and potentially a source of error (misclassification) dependent on the expertise and focus of the observer, which naturally limits the efficacy of this approach.

Here, we introduce machine learning-based computer vision techniques to automate the ‘scoring’ process. This would foster objectivity in assessment, time savings and the release of human resources with the exception of spot validation for quality assurance.  If adopted, this method and similar methods using automated approaches could be used to facilitate decisions around aquaculture operations and environmental monitoring.
