Artificial Intelligence (AI) has rapidly evolved into a deep tech powerhouse, revolutionising industries ranging from healthcare to finance and everything in between. As AI technology becomes increasingly complex, so does the terminology surrounding it.
1. AI refers to machines or software that can perform tasks requiring human intelligence. These tasks include reasoning, learning, problem-solving, understanding language, and recognizing patterns. AI is the umbrella term encompassing machine learning (ML), deep learning (DL), and other subfields of computational intelligence.
2. Machine Learning is a subset of AI that allows systems to learn from data and improve their performance over time without being explicitly programmed. ML models analyze large datasets to identify patterns and make predictions or decisions. Applications range from recommendation systems (like Netflix) to fraud detection in banking.
3. Deep Learning is a specialized branch of machine learning that uses neural networks with multiple layers (often referred to as deep neural networks). These models are particularly effective at processing vast amounts of data and can be used for tasks such as image recognition, natural language processing, and speech recognition. DL has been instrumental in major AI breakthroughs, from self-driving cars to advanced medical diagnostics.
1. Neural networks are a series of algorithms designed to recognize relationships in a set of data, modeled after the human brain’s network of neurons. Each node, or "neuron," in the network processes data and passes it to the next layer, helping the system identify complex patterns. Neural networks are the foundation of most deep learning models.
2. NLP is the field of AI focused on enabling computers to understand, interpret, and respond to human language in a way that is both meaningful and useful. Applications of NLP include chatbots, voice assistants like Siri and Alexa, sentiment analysis, and language translation tools.

1. In supervised learning, models are trained on labeled data, meaning the input data comes with corresponding output labels. The goal of supervised learning is to make predictions or decisions based on this labeled dataset. Examples include spam detection in emails and image classification.
2. Unlike supervised learning, unsupervised learning works with data that doesn’t have labeled outputs. The system is tasked with identifying hidden patterns or structures in the data. Clustering and association are common unsupervised learning tasks, used in market segmentation and recommendation engines.
3. This hybrid approach uses both labeled and unlabeled data for training. Semi-supervised learning is particularly useful when acquiring large labeled datasets is expensive or time-consuming. A common application is in image recognition, where labeling every image might not be feasible.
1. Transfer Learning allows a pre-trained model, developed for one task, to be repurposed for another, related task. This approach is particularly effective in deep learning, where models trained on vast datasets (such as ImageNet) can be fine-tuned to perform well on different but related tasks, saving time and computational resources.
2. Generative AI refers to algorithms that can create new content such as images, text, audio, or video. These models learn patterns from existing data and generate new examples that mirror those patterns. Examples of generative AI include OpenAI’s GPT models, which can write text, and DALL-E, which generates images from textual descriptions.
3. Autonomous systems are machines or software that operate without human intervention. These systems often use AI algorithms, including reinforcement learning and computer vision, to make decisions and execute actions independently. Autonomous vehicles, drones, and robotic process automation (RPA) are common examples.
1. Edge AI refers to deploying AI algorithms locally on devices like smartphones, sensors, and IoT devices rather than relying on cloud-based systems. This allows real-time data processing with lower latency, which is critical for applications like autonomous driving, smart homes, and wearable health tech.
2. Explainable AI aims to create AI systems whose decisions can be understood and explained by humans. In traditional deep learning models, the decision-making process is often seen as a “black box,” but XAI techniques ensure transparency and interpretability, which are vital in areas like healthcare and finance where understanding the rationale behind decisions is critical.
3. Quantum AI refers to the application of quantum computing to solve AI problems. Quantum computers, which leverage the principles of quantum mechanics, can potentially process information much faster than classical computers. While still in its early stages, Quantum AI holds promise for solving computationally intensive tasks like large-scale optimization and cryptography.
1. Data mining involves extracting useful information from large datasets. In AI, data mining techniques are used to prepare datasets for training models by identifying patterns, anomalies, or relationships in the data. It is often used in business analytics, customer segmentation, and fraud detection.
2. AI ethics is the branch of ethics concerned with how AI impacts individuals and society at large. Topics within AI ethics include privacy, bias, fairness, accountability, and the potential consequences of AI in areas like employment and surveillance. As AI becomes more prevalent, ensuring ethical deployment is a growing concern.
3. AI bias occurs when an AI system produces results that are systematically prejudiced due to biased training data or flawed algorithms. Bias in AI can lead to unfair treatment of certain groups, particularly in sensitive applications like hiring, lending, and law enforcement. Identifying and mitigating bias is a critical part of responsible AI development.
1. Federated learning is a distributed approach to machine learning that allows models to be trained across multiple devices without centralizing data. Each device trains the model locally and only shares the updates, keeping the raw data on the device. This technique is particularly valuable for preserving privacy in applications like healthcare and mobile services.
2. RPA refers to software robots or “bots” that automate repetitive tasks typically performed by humans. These bots follow predefined rules to interact with digital systems, performing tasks like data entry, processing transactions, and managing emails. RPA is frequently used to streamline operations in industries such as finance, insurance, and customer service.
