Discriminative Sample-Guided and Parameter-Efficient Feature Space Adaptation for Cross-Domain Few-Shot Learning

1 code implementation7 Mar 2024 Rashindrie Perera, Saman Halgamuge

In this paper, we look at cross-domain few-shot classification which presents the challenging task of learning new classes in previously unseen domains with few labelled examples.

Day-ahead regional solar power forecasting with hierarchical temporal convolutional neural networks using historical power generation and weather data

no code implementations4 Mar 2024 Maneesha Perera, Julian De Hoog, Kasun Bandara, Damith Senanayake, Saman Halgamuge

In this work, we propose two deep-learning-based regional forecasting methods that can effectively leverage both types of time series (aggregated and individual) with weather data in a region.

When To Grow? A Fitting Risk-Aware Policy for Layer Growing in Deep Neural Networks

no code implementations6 Jan 2024 Haihang Wu, Wei Wang, Tamasha Malepathirana, Damith Senanayake, Denny Oetomo, Saman Halgamuge

Neural growth is the process of growing a small neural network to a large network and has been utilized to accelerate the training of deep neural networks.

GINN-LP: A Growing Interpretable Neural Network for Discovering Multivariate Laurent Polynomial Equations

1 code implementation18 Dec 2023 Nisal Ranasinghe, Damith Senanayake, Sachith Seneviratne, Malin Premaratne, Saman Halgamuge

In this work, we propose GINN-LP, an interpretable neural network to discover the form and coefficients of the underlying equation of a dataset, when the equation is assumed to take the form of a multivariate Laurent Polynomial.

Multi-Resolution, Multi-Horizon Distributed Solar PV Power Forecasting with Forecast Combinations

1 code implementation22 Jun 2022 Maneesha Perera, Julian De Hoog, Kasun Bandara, Saman Halgamuge

We propose a forecast combination approach based on particle swarm optimization (PSO) that will enable a forecaster to produce accurate forecasts for the task at hand by weighting the forecasts produced by individual models.

A machine learning accelerated inverse design of underwater acoustic polyurethane coatings with cylindrical voids

no code implementations2 Mar 2022 Hansani Weeratunge, Zakiya Shireen, Sagar Iyer, Richard Sandberg, Saman Halgamuge, Adrian Menzel, Andrew Phillips, Elnaz Hajizadeh

Here, we report the development of a detailed "Materials Informatics" framework for the design of acoustic coatings for underwater sound attenuation through integrating Machine Learning (ML) and statistical optimization algorithms with a Finite Element Model (FEM).

Self Organizing Nebulous Growths for Robust and Incremental Data Visualization

1 code implementation9 Dec 2019 Damith Senanayake, Wei Wang, Shalin H. Naik, Saman Halgamuge

In addition, SONG is capable of handling new data increments, no matter whether they are similar or heterogeneous to the already observed data distribution.

Improving MMD-GAN Training with Repulsive Loss Function

1 code implementation ICLR 2019 Wei Wang, Yuan Sun, Saman Halgamuge

To address this issue, we propose a repulsive loss function to actively learn the difference among the real data by simply rearranging the terms in MMD.
