Depth Estimation using Weighted-loss and Transfer Learning

no code implementations11 Apr 2024 Muhammad Adeel Hafeez, Michael G. Madden, Ganesh Sistu, Ihsan Ullah

The optimized loss function is a combination of weighted losses to which enhance robustness and generalization: Mean Absolute Error (MAE), Edge Loss and Structural Similarity Index (SSIM).

Beyond the Known: Adversarial Autoencoders in Novelty Detection

no code implementations6 Apr 2024 Muhammad Asad, Ihsan Ullah, Ganesh Sistu, Michael G. Madden

The first is that we compute the novelty probability by linearizing the manifold that holds the structure of the inlier distribution.

Robust Classification of High-Dimensional Spectroscopy Data Using Deep Learning and Data Synthesis

no code implementations26 Mar 2020 James Houston, Frank G. Glavin, Michael G. Madden

This paper presents a new approach to classification of high dimensional spectroscopy data and demonstrates that it outperforms other current state-of-the art approaches.

Using a Game Engine to Simulate Critical Incidents and Data Collection by Autonomous Drones

no code implementations31 Aug 2018 David L. Smyth, Frank G. Glavin, Michael G. Madden

Using a game engine, we have developed a virtual environment which models important aspects of critical incident scenarios.

Adaptive Shooting for Bots in First Person Shooter Games Using Reinforcement Learning

no code implementations14 Jun 2018 Frank G. Glavin, Michael G. Madden

In current state-of-the-art commercial first person shooter games, computer controlled bots, also known as non player characters, can often be easily distinguishable from those controlled by humans.

Analysis of the Effect of Unexpected Outliers in the Classification of Spectroscopy Data

no code implementations14 Jun 2018 Frank G. Glavin, Michael G. Madden

Multi-class classification algorithms are very widely used, but we argue that they are not always ideal from a theoretical perspective, because they assume all classes are characterized by the data, whereas in many applications, training data for some classes may be entirely absent, rare, or statistically unrepresentative.

Learning to Shoot in First Person Shooter Games by Stabilizing Actions and Clustering Rewards for Reinforcement Learning

no code implementations13 Jun 2018 Frank G. Glavin, Michael G. Madden

While reinforcement learning (RL) has been applied to turn-based board games for many years, more complex games involving decision-making in real-time are beginning to receive more attention.

DRE-Bot: A Hierarchical First Person Shooter Bot Using Multiple Sarsa(λ) Reinforcement Learners

no code implementations13 Jun 2018 Frank G. Glavin, Michael G. Madden

This paper describes an architecture for controlling non-player characters (NPC) in the First Person Shooter (FPS) game Unreal Tournament 2004.

One-Class Classification: Taxonomy of Study and Review of Techniques

no code implementations30 Nov 2013 Shehroz S. Khan, Michael G. Madden

In this paper we present a unified view of the general problem of OCC by presenting a taxonomy of study for OCC problems, which is based on the availability of training data, algorithms used and the application domains applied.
