What is limited memory AI?

There are numerous terms and definitions in the field of artificial intelligence which can make it hard to distinguish categories from subsets or types of artificial intelligence. Number of subsets of AI include machine learning, big data and natural language processing, but this article will cover only one type of artificial intelligence – limited memory. Other types of AI include reactive machines, theory of mind, and self-awareness.

Limited memory consists of machine learning models that extract knowledge from previously learned information, facts, stored data or events. As distinct from reactive machines, limited memory is able to learn from the past by analysing actions or data given to them with the purpose of building probationary knowledge.

This type of AI is employed by virtual voice assistants, chatbots, self-driving cars, and several other technologies. 

Autonomous vehicles, also known as self-driving cars, use limited memory technology that relies on a combination of observationally gathered and integrated knowledge. Their ability to drive and function adequately among human-reliant vehicles comes from analysing their environment, detecting patterns or alterations in external factors, and adapting as required.

Self-driving cars don’t just monitor their environment, but also take into account the movement of other traffic participants found in their line of sight. Its software analyses the data and decides on adapting the speed or choosing the direction of the vehicle. In the past, autonomous vehicles without limited memory AI needed up to 100 seconds to react and make decisions based on external factors. After the implementation of limited memory, response time on machine-based observations has decreased tremendously, showing the value of limited memory AI.

With AI penetrating our daily lives with the intention to stay and make our lives easier it is interesting to see how quickly it is developing and evolving, allowing different industries to advance. Science fiction is gradually becoming reality with new technological developments emerging every day. Who knows what tomorrow brings?
