Dynamic graph representation is a way of modelling and storing graphs where the structure or data can change over time. This approach allows for updates such as adding or removing nodes and edges without needing to rebuild the entire graph from scratch. It is often used in situations where relationships between items are not fixed…

Graph-Based Anomaly Detection
Graph-based anomaly detection is a technique used to find unusual patterns or outliers in data that can be represented as networks or graphs, such as social networks or computer networks. It works by analysing the structure and connections between nodes to spot behaviours or patterns that do not fit the general trend. This method is…
Graph Signal Processing
Graph Signal Processing (GSP) is a field that studies how to analyse and process data that lives on graphs, such as social networks or transportation systems. It extends traditional signal processing, which deals with time or space signals, to more complex structures where data points are connected in irregular ways. GSP helps to uncover patterns,…
Imitation Learning Techniques
Imitation learning techniques are methods in artificial intelligence where a computer or robot learns to perform tasks by observing demonstrations, usually from a human expert. Instead of programming every action or rule, the system watches and tries to mimic the behaviour it sees. This approach helps machines learn complex tasks quickly by copying examples, making…
Multi-Objective Reinforcement Learning
Multi-Objective Reinforcement Learning is a type of machine learning where an agent learns to make decisions by balancing several goals at the same time. Instead of optimising a single reward, the agent considers multiple objectives, which can sometimes conflict with each other. This approach helps create solutions that are better suited to real-life situations where…
Reward Sparsity Handling
Reward sparsity handling refers to techniques used in machine learning, especially reinforcement learning, to address situations where positive feedback or rewards are infrequent or delayed. When an agent rarely receives rewards, it can struggle to learn which actions are effective. By using special strategies, such as shaping rewards or providing hints, learning can be made…
Policy Gradient Optimization
Policy Gradient Optimisation is a method used in machine learning, especially in reinforcement learning, to help an agent learn the best actions to take to achieve its goals. Instead of trying out every possible action, the agent improves its decision-making by gradually changing its strategy based on feedback from its environment. This approach directly adjusts…
Sample-Efficient Reinforcement Learning
Sample-efficient reinforcement learning is a branch of artificial intelligence that focuses on training systems to learn effective behaviours from as few interactions or data samples as possible. This approach aims to reduce the amount of experience or data needed for an agent to perform well, making it practical for real-world situations where gathering data is…
Model Performance Tracking
Model performance tracking is the process of monitoring how well a machine learning model is working over time. It involves collecting and analysing data on the model’s predictions to see if it is still accurate and reliable. This helps teams spot problems early and make improvements when needed.
Inference Pipeline Optimization
Inference pipeline optimisation is the process of making the steps that turn machine learning models into predictions faster and more efficient. It involves improving how data is prepared, how models are run, and how results are delivered. The goal is to reduce waiting time and resource usage while keeping results accurate and reliable.
