A Multi-Dimensional, Cross-Domain and Hierarchy-Aware Neural Architecture for ISO-Standard Dialogue Act Tagging

no code implementations COLING 2022 Stefano Mezza, Wayne Wobcke, Alan Blair

Dialogue Act tagging with the ISO 24617-2 standard is a difficult task that involves multi-label text classification across a diverse set of labels covering semantic, syntactic and pragmatic aspects of dialogue.

Organ localisation using supervised and semi supervised approaches combining reinforcement learning with imitation learning

no code implementations6 Dec 2021 Sankaran Iyer, Alan Blair, Laughlin Dawes, Daniel Moses, Christopher White, Arcot Sowmya

The results of experiments on localisation of the Spleen, Left and Right Kidneys in CT Images using supervised and semi supervised learning (SSL) demonstrate the ability to address data limitations with a much smaller data set and fewer annotations, compared to other state-of-the-art methods.

Can Label-Noise Transition Matrix Help to Improve Sample Selection and Label Correction?

no code implementations29 Sep 2021 Yu Yao, Xuefeng Li, Tongliang Liu, Alan Blair, Mingming Gong, Bo Han, Gang Niu, Masashi Sugiyama

Existing methods for learning with noisy labels can be generally divided into two categories: (1) sample selection and label correction based on the memorization effect of neural networks; (2) loss correction with the transition matrix.

Man versus Machine: AutoML and Human Experts' Role in Phishing Detection

no code implementations27 Aug 2021 Rizka Purwanto, Arindam Pal, Alan Blair, Sanjay Jha

Our paper compares the performances of six well-known, state-of-the-art AutoML frameworks on ten different phishing datasets to see whether AutoML-based models can outperform manually crafted machine learning models.

Eccentric Regularization: Minimizing Hyperspherical Energy without explicit projection

no code implementations23 Apr 2021 Xuefeng Li, Alan Blair

Several regularization methods have recently been introduced which force the latent activations of an autoencoder or deep neural network to conform to either a Gaussian or hyperspherical distribution, or to minimize the implicit rank of the distribution in latent space.

Simeon -- Secure Federated Machine Learning Through Iterative Filtering

no code implementations13 Mar 2021 Nicholas Malecki, Hye-Young Paik, Aleksandar Ignjatovic, Alan Blair, Elisa Bertino

Federated learning enables a global machine learning model to be trained collaboratively by distributed, mutually non-trusting learning agents who desire to maintain the privacy of their training data and their hardware.

Complexity-based speciation and genotype representation for neuroevolution

no code implementations11 Oct 2020 Alexander Hadjiivanov, Alan Blair

This paper introduces a speciation principle for neuroevolution where evolving networks are grouped into species based on the number of hidden neurons, which is indicative of the complexity of the search space.

PhishZip: A New Compression-based Algorithm for Detecting Phishing Websites

Multi-hop Reading Comprehension via Deep Reinforcement Learning based Document Traversal

no code implementations23 May 2019 Alex Long, Joel Mason, Alan Blair, Wei Wang

To address MH-QA specifically, we propose a Deep Reinforcement Learning based method capable of learning sequential reasoning across large collections of documents so as to pass a query-aware, fixed-size context subset to existing models for answer extraction.

Sparse, guided feature connections in an Abstract Deep Network

no code implementations16 Dec 2014 Anthony Knittel, Alan Blair

The ADN system provides a method for developing a very sparse, deep feature topology, based on observed relationships between features, that is able to find solutions in irregular domains, and initialize a network prior to gradient descent learning.
