AI & Bias - What are Algorithms and how do they work?
People & Blogs
Introduction
In our everyday lives, algorithms are silently influencing the decisions we make, the information we consume, the places we visit, and the connections we form. Whether it’s stumbling across a new favorite biryani taco recipe or locating the nearest laundromat in a hurry, algorithms are integral to our daily experiences. Streaming services analyze our tastes to deliver personalized recommendations. Algorithms have become deeply woven into the fabric of our lives, yet many of us may not fully understand what they are or how they function.
Understanding Algorithms
An algorithm is a precise set of instructions or steps designed to solve a specific problem. While algorithms are often expressed in code, they can also exist in other forms, such as recipes. For example, if you have various ingredients and want to make a cake, following a cake recipe provides the algorithm that transforms your ingredients into a delicious outcome.
Search engine algorithms function similarly, but they are more complex. At the core of a search engine lies a network of algorithms that work in concert. When you submit a search query, the first algorithm attempts to comprehend your request by dissecting the search terms, checking for spelling errors, and considering synonyms to derive meaning.
Once the meaning is determined, another algorithm searches a colossal database, which contains information about hundreds of billions of web pages. This database is populated by algorithms known as crawlers, which continuously scour the web for new and updated content.
Ranking and Relevance
After generating a list of potential results, the next challenge is determining which pages to display and in what order. Here, the algorithm employs various criteria to rank search results based on factors such as expertise, authoritativeness, and trustworthiness. It evaluates how many credible sites link back to each result and assesses user-friendliness.
Finally, the algorithm personalizes the search results by comparing them against your web history and personal information to present content that is best suited to you. In mere seconds, the search engine delivers personalized results, showcasing the remarkable efficiency of algorithms.
Applications Beyond Search Engines
Algorithms are not limited to search engines; they enhance numerous aspects of our lives. For instance, when you send a text message, algorithms are used to transmit it to the recipient securely. Online shopping relies on algorithms to protect your credit card information from cyber threats.
In medical imaging, algorithms analyze MRI scans, and in meteorology, they predict storm paths. In drug discovery, algorithms assist in developing treatments for diseases. As we navigate an increasingly data-rich world, algorithms are learning more about us and are shaping the way we interact with various technologies.
The Challenge of Bias
While algorithms offer significant benefits, they also raise critical concerns, primarily regarding bias. Returning to our discussion of search engines, the quality control mechanisms that determine which sites are authoritative and trustworthy are not always transparent. Questions about who determines these metrics and how they are quantified are essential, especially when algorithms affect societal viewpoints and accessibility to information.
In conclusion, algorithms are indispensable tools designed to solve problems efficiently. However, as they become more integrated into our daily lives, understanding their implications, including the potential for bias, becomes increasingly important.
