The Role of Data in AI
Data serves as the foundation of AI providing the raw material from which models learn, make predictions, and generate insights.
Big data plays a significant role in training sophisticated AI systems, with large and diverse datasets enhancing the model’s ability to handle complex tasks, as seen in applications such as language translation and autonomous vehicles.
[Big Data: Refers to extremely large and complex datasets that are generated at high velocity from various sources. These datasets are difficult to process using traditional data management tools but can provide valuable insights when effectively analyzed using advanced techniques such as AI and machine learning.]
Data Collection Techniques
Data is gathered through a variety of methods including surveys, sensors, and web scraping, each offering unique insights depending on the source and context.
Surveys: Involve directly soliciting information from respondents, allowing researchers to gather targeted, structured data on specific topics, preferences, or behaviors
Sensors: Data collected from devices that monitor and measure physical environments and/or processes, such as temperature, motion, or pressure sensors, providing real-time, continuous streams of data.
Web Scraping: This means automatically extracting large quantities of data from websites, such as social media posts, product reviews, or news articles, that can be used to uncover trends, sentiments, and insights.
Other Types: Data can also be collected from application programming interfaces (APIs), crowdsourcing, user interactions, A/B testing, simulations, and more. Also, it can be used in an AI model.
Data Preprocessing: Ensures that the data used in and AI model is clean consistent, and ready for analysis, thereby improving model accuracy and performance. It includes: Handing missing and incomplete data, normalization, scaling, and data transformation.
Data Cleaning: Involves identifying and correcting errors within datasets, including outliers and data “noise” to maintain the model’s integrity
