AI without the hype: models, agents and use cases that work in production.
Adversarial machine learning studies deliberate attacks on AI systems (evasion, poisoning and model extraction) and the defenses used to resist them, chiefly adversarial training, robustness certification and monitoring the distribution of production input data.
Federated learning trains AI models collaboratively across many devices or organisations without moving the original data: each participant trains locally and sends only gradients to the central server. Formalised by Google in 2016, it does not guarantee privacy on its own: it needs differential privacy or secure aggregation to prevent leaks from those gradients.
Recommendation systems are the invisible engine behind Netflix, Amazon, and Spotify. Collaborative filtering predicts individual preferences by analysing the behaviour of millions of users without examining item content: 80% of what Netflix viewers watch and 35% of Amazon sales come from algorithmic recommendations.
Explainable AI (XAI) is the set of techniques that open the black box of AI models and answer why they made a given decision. Methods such as LIME, SHAP and Grad-CAM activation maps are the most widely used. Its adoption is mandatory in regulated environments: healthcare, justice, and financial services.
Reinforcement learning is the AI technique in which an agent learns to make optimal decisions through trial and error, without labelled data: it acts in an environment, receives a reward or penalty based on the outcome, and adjusts its strategy to maximise long-term cumulative reward.
Intelligent automation combines AI, machine learning, and physical robots that perceive, decide, and adapt in real time instead of following a fixed script. It is transforming manufacturing, logistics, healthcare, and food processing, and by 2024 there were already more than 4.6 million industrial robots active worldwide, per the IFR.
Computer vision is the branch of artificial intelligence that lets machines interpret digital images: detecting objects, segmenting regions and recognising patterns through convolutional neural networks. Since 2012, when AlexNet cut ImageNet classification error to 15.3%, it has spread into manufacturing, medicine, transport and precision agriculture.
Natural Language Processing (NLP) is the AI discipline that enables machines to understand, interpret, and generate human text and speech. Powered by the transformer architecture since 2017, NLP drives chatbots, automatic translation, and clinical diagnosis tools, with open challenges in causal reasoning, energy efficiency, and bias mitigation.
Deep neural networks are today the foundation of almost every artificial intelligence application: from facial recognition to machine translation. Built on architectures like CNNs, RNNs, and Transformers, deep learning has transformed computer vision, speech recognition, and natural language processing over the last decade.
