- Finance: Financial institutions like Wells Fargo segment customers based on factors like credit score, spending behaviour and account activity, offering tailored financial products.
- Airlines: Companies like Delta and American Airlines segment their customer base to offer personalised rewards, services and promotions based on frequent flyer status and travel patterns.
Computer vision applications
Whether you've used a camera on a smartphone or travelled through airport security, almost all of us have experienced a computer vision application in one way or another. Computer vision applications are the real-world uses of technology that allow computers and systems to ‘see’ and interpret visual information from the world around them.
Let's explore what the main types of computer vision applications are and how they can be used to add value.
Image recognition and classification
Image recognition is one of the most widely recognised applications of computer vision, a branch of AI focused on enabling machines to interpret and analyse visual data. In image recognition, an ML model is trained to identify and classify objects, features or patterns in images.
For instance, facial recognition software is used to identify individuals in photos, while autonomous vehicles rely on image recognition to detect road signs, pedestrians and other vehicles. In retail, image recognition can be used to automatically catalogue products or detect damaged items in warehouses. By allowing machines to ‘see’ and understand images, businesses can automate processes, improve accuracy and enhance user experiences.
Object detection and tracking
Object detection extends the concept of image recognition by not only identifying objects within images but also locating and tracking them in real time. This is especially useful in industries like security, manufacturing and logistics.
For example, in surveillance systems, AI-powered cameras can detect and track people or vehicles as they move through a monitored area, triggering alerts when unusual activity is detected. In warehouses, object detection can be used to track inventory as it moves throughout the facility, improving inventory management and efficiency. Real-time object tracking has applications in robotics, where robots must navigate environments and interact with objects autonomously.
Facial recognition
Facial recognition is a subset of image recognition that specifically focuses on identifying individuals based on unique facial features. This technology has gained significant traction in sectors like security, retail and health care.
Airports use facial recognition for faster and more secure passenger identification, while retail stores use it for personalised customer experiences, such as offering discounts or loyalty rewards to frequent visitors. However, facial recognition also raises privacy concerns, and its ethical implications are still widely debated. Despite these challenges, it remains an influential tool in the security and customer service industries.
Computer vision empowers machines to interpret visual data, driving smarter automation and sharper insights. From image recognition for sorting products or enabling autonomous vehicles to object detection for real-time tracking in security and logistics and facial recognition for streamlined identification — these tools boost efficiency, enhance user experiences and open new possibilities across industries.
NLP and large language models (LLMs)
NLP offers a range of powerful tools that help businesses better understand and interact with their customers. In this section, you'll explore key applications of NLP — sentiment analysis, chatbots and virtual assistants, and text summarisation — highlighting how these technologies can enhance customer engagement, streamline operations and improve decision-making through actionable insights.
Sentiment analysis
Sentiment analysis is an application of NLP that focuses on understanding the emotional tone or sentiment expressed in text. By analysing customer reviews, social media posts or feedback surveys, businesses can gauge public opinion about their products, services or brand.
ML models trained on vast amounts of text data can determine whether the sentiment is positive, negative or neutral, and even detect the underlying emotions such as joy, frustration or anger. This insight allows companies to respond proactively to customer concerns, improve products and adjust marketing strategies to better resonate with their audience.
Chatbots and virtual assistants
Chatbots and virtual assistants are becoming essential tools for automating customer service. These AI-powered systems use NLP and LLMs to understand and respond to customer queries in natural language.
Whether embedded on websites or integrated into messaging apps, chatbots can handle a wide range of tasks, from answering frequently asked questions to processing orders and troubleshooting issues. Virtual assistants, like Siri or Alexa, go a step further by integrating with devices to perform tasks such as setting reminders, controlling smart home devices or providing weather updates. By automating routine interactions, businesses can improve efficiency, reduce operational costs and offer 24/7 support to customers.
Text summarisation
With the increasing volume of text data available across industries, businesses often struggle to process and extract useful information. Text summarisation uses ML models to condense large volumes of text into concise summaries, making it easier for users to digest important information quickly.
For example, news outlets use summarisation algorithms to generate concise headlines or brief summaries of lengthy articles. Legal firms can use it to summarise contracts or case documents, saving time for lawyers and clients alike. By automating the process of summarising text, businesses can streamline workflows and improve information accessibility.
NLP enables businesses to analyse and interpret human language, providing valuable insights and enhancing customer interactions. Together, these tools help businesses make informed decisions, enhance user experiences and optimise operations.
