Artificial intelligence now pervades many parts of our lives and is here to stay for the foreseeable future. This bird’s eye view of the top open source AI tools serves as a reminder of how AI has already impacted our lives.
Imagine the digital future, in which you are dining at a restaurant. In this future scenario, right from the food served on your plate to the waiter who attends to you, everything has been arranged according to your taste and personality traits, without you being asked a single question. Imagine a world in which even the angle at which a plate is served at this restaurant or the smile of the waiter can be calculated with potential suggestions to suit your personality or mood. In such a world, if you are trying to buy a pair of shoes, you’d make a few swipes on your smartphone and all the available shoes in your favourite colour, with the accurate shape of the sole and height of heel, will show up on your screen. All this thanks to machine learning (ML) — and the possibilities are endless.
Artificial intelligence or AI has now penetrated many aspects of our lives. Let’s talk about 2018! All these voice recognition systems we use to search on Google and command our smartphones are the beginning of a new age. We have not yet understood the full potential of AI yet. A limited version of AI technology is already fitted inside our cars. Apple’s Siri, Google’s OK Google, and Amazon’s Echo services are already in use, analysing your tone and voice along with answering your query. These AI-backed services have a natural language processing system and are able to respond to the commands. You can now get directions to a location and look for a specific restaurant, all by just swiping your fingers on a screen!
Driverless cars are now on trial and the population of robots is on the rise, as they are expected to replace humans in certain fields in the very near future. You could expect robot hotel receptionists and robots to clean our houses, reducing us to couch potatoes. Oh well, let’s stick to the brighter side of things!
Machine learning is a branch of artificial intelligence that deals with the self-learning of computers. This means that machines effectively learn to grow and change without any need for programming.
And automation is the new emerging technology through which no more human assistance is required during any process. In other words, this is programmed control. This process uses different control frameworks for different systems or equipment such as electronic hardware, production lines, boilers, phone systems, boats, airplanes and vehicles, so that there is insignificant or less human mediation. A few procedures have already been totally computerised.
The automation, which we know today, began with simple machines, like water wheels, in the 11th century. Gradually, humans started developing on these simple machines and innovating over time.
Open source artificial intelligence tools
Now let’s look at a few open source AI tools that are helping researchers currently working on their projects.
Apache Mahout: This is an open source machine learning tool under the Apache licence. It has been designed to simplify working on common math problems involving statistics and linear algebra. This ML tool has been designed by the Apache Software Foundation and is built on a platform called Mahout Hadoop. Data analysts use this open source machine learning tool to carry out a critical and detailed analysis of Big Data. An understanding of quantitative data helps to extract useful information and pinpoint the trends. Mahout’s algorithms help users in clustering and grouping Big Data by first saving the data in the Hadoop distributed file system. It has a cross-platform operating system, and it gives users an environment with R-like syntax.
Distributed Machine Learning Toolkit (DMTK): This is an open source ML tool that simplifies various tasks on Big Data. DMTK was released by Microsoft, with new and advanced algorithms getting added to this toolkit regularly. This toolkit lets researchers experiment with algorithms by modifying them and tweaking them according to their needs. Previously, researchers needed many computational resources to work on Big Data, since it has been proved that bigger data models lead to better results, but this was quite challenging. The DMTK enables innovation in both the system’s algorithm and in ML algorithms.
Open Neural Networks (OpenNN): This is an open source library written in the C++ language. It has been designed for deep learning and for the implementation of neural networks. This library has an easy-to-understand and deep architecture, and is used in advanced ML research. This open source library is used in the logistics and marketing verticals. OpenNN also allows high performance computing as it has a higher processing speed.
OpenCyc: This is an open source general knowledge database that makes text understanding possible. Cycorp launched OpenCyc to make sure that users have unrestricted access to this knowledge base and that they can use OpenCyc in different applications. The vast knowledge base of OpenCyc contains a diverse range of concepts, facts, taxonomies, assertions and rules. It is available in two forms, i.e., ontology as well as the semantic Web endpoints. The latter can also be referred to as the permanent URIs, which means that both the RDF representations and human-readable forms are returned to the users.
Cycorp enables apps to sift through a large database and process the relevant information to come up with an accurate interpretation. It helps in the differentiation of relative words and synonyms of a particular key search word and ensures the app performs like a person, exhibiting human cognitive abilities and discernment. OpenCyc has assisted AI researchers in their projects so they can now use its ontologies to ensure machine learning (ML) that can be interrupted by humans to prevent machines from causing harm. Cyc has revolutionised ML by enabling the apps to learn the complicated reasoning and logic of the human mind.
