Definitions:
- Validation Set: A subset of data used to evaluate the performance of a machine learning model during the training process. The validation set helps to fine-tune the model's hyperparameters and prevent overfitting by providing an independent measure of the model's performance. It is distinct from the training set and the test set.
- Vector Databases: Databases designed to store and manage vectors, which are high-dimensional data representations often used in machine learning and artificial intelligence. Vector databases support efficient querying and similarity searches, making them ideal for applications such as recommendation systems, image recognition, and natural language processing.
- Vectorisation: The process of converting data into a vector format, where data points are represented as numerical vectors. Vectorisation is a crucial step in data preprocessing for machine learning, enabling algorithms to process and analyse the data efficiently. It is commonly used in natural language processing, image processing, and other data-intensive applications.
- Version Control Systems (VCS): Software tools that help manage changes to source code over time. Version control systems allow developers to track changes, collaborate on code, and revert to previous versions if necessary. Popular VCS tools include Git, Subversion (SVN), and Mercurial. They are essential for maintaining code integrity and facilitating team collaboration in software development.
- Virtual Machines (VMs): Emulated computer systems that run on top of a physical machine. Virtual machines provide a complete computing environment, including an operating system, applications, and data, and can be isolated from the host system. VMs are used for various purposes, such as running multiple operating systems on a single physical machine, testing software, and creating isolated development environments.
- Virtual Private Network (VPN): A technology that creates a secure and encrypted connection over a less secure network, such as the internet. VPNs are used to protect data privacy and security by encrypting data traffic and routing it through secure servers. They are commonly used for remote access to corporate networks, secure browsing, and protecting online activities.
- Virtual Reality (VR): A technology that creates a simulated environment, giving users the impression of being present in a virtual world. VR uses head-mounted displays, sensors, and other devices to provide an immersive experience. It is used in various applications, including gaming, education, training, and virtual tourism.
- Visual Studio Code: A popular, lightweight, and extensible code editor developed by Microsoft. Visual Studio Code supports a wide range of programming languages and provides features such as syntax highlighting, code refactoring, debugging, and integration with version control systems. It is widely used by developers for coding and debugging applications.
- Visualisation: The process of creating visual representations of data to facilitate understanding and communication. Visualisation involves transforming data into charts, graphs, maps, and other visual formats to reveal patterns, trends, and insights. Effective visualisation is crucial in data science, business intelligence, and user experience design, as it helps stakeholders to make informed decisions.
- Voice User Interface (VUI): An interface that enables users to interact with a digital system using voice commands. VUIs use speech recognition and natural language processing to understand and respond to user inputs. They are commonly used in virtual assistants, smart speakers, and other voice-enabled devices to provide a hands-free and intuitive user experience.
