2022 Trends in Artificial Intelligence and Machine Learning: Reasoning Meets Learning - insideBIGDATA

#artificialintelligence

For most organizations, the bifurcation of Artificial Intelligence has been as stark as it's been simplistic. AI was either machine learning or rules-based approaches (the former of which outnumbered the latter), supervised or unsupervised learning, computer vision or natural language technologies. Due to a number of developments in the past year around ModelOps, composite AI, and neuro-symbolic AI, there's currently a growing awareness throughout the enterprise that AI--and its ROI--not only involves each of the foresaid dimensions, but does so optimally when they operate in conjunction with each other to pare the costs, difficulty, and time they otherwise require. CTO Marco Varone, "There are situations where you can get better results combining the different approaches; there are situations where you can use both and it's not too different, and there are situations where it's better with one approach." By incorporating the full AI spectrum into their toolkits, organizations can not only deploy the most appropriate method for their cognitive computing tasks, but also exploit surrounding areas of opportunity like intellectual property for machine learning models, cloud or Internet of Things use cases, and explainable AI. "The future is what we call a hybrid or composite approach where you use all the techniques that are available and you put them together in a way that the end user or data scientist trying to solve a specific problem can take different techniques and decide to use the ones giving the best results," Varone predicted.


Symbolic AI: The key to the thinking machine

#artificialintelligence

Even as many enterprises are just starting to dip their toes into the AI pool with rudimentary machine learning (ML) and deep learning (DL) models, a new form of the technology known as symbolic AI is emerging from the lab that has the potential to upend both the way AI functions and how it relates to its human overseers. Symbolic AI's adherents say it more closely follows the logic of biological intelligence because it analyzes symbols, not just data, to arrive at more intuitive, knowledge-based conclusions. It's most commonly used in linguistics models such as natural language processing (NLP) and natural language understanding (NLU), but it is quickly finding its way into ML and other types of AI where it can bring much-needed visibility into algorithmic processes. The technology actually dates back to the 1950s, says expert.ai's Luca Scagliarini, but was considered old-fashioned by the 1990s when demand for procedural knowledge of sensory and motor processes was all the rage.


Getting AI to Reason: Using Neuro-Symbolic AI for Knowledge-Based Question Answering

#artificialintelligence

Language is what makes us human. Asking questions is how we learn. Building on the foundations of deep learning and symbolic AI, we have developed technology that can answer complex questions with minimal domain-specific training. Initial results are very encouraging – the system outperforms current state-of-the-art techniques on two prominent datasets with no need for specialized end-to-end training. As this technology matures, it will be possible to use it for better customer support, business intelligence, medical informatics, advanced discovery, and much more.


Neurosymbolic AI: The 3rd Wave

arXiv.org Artificial Intelligence

Current advances in Artificial Intelligence (AI) and Machine Learning (ML) have achieved unprecedented impact across research communities and industry. Nevertheless, concerns about trust, safety, interpretability and accountability of AI were raised by influential thinkers. Many have identified the need for well-founded knowledge representation and reasoning to be integrated with deep learning and for sound explainability. Neural-symbolic computing has been an active area of research for many years seeking to bring together robust learning in neural networks with reasoning and explainability via symbolic representations for network models. In this paper, we relate recent and early research results in neurosymbolic AI with the objective of identifying the key ingredients of the next wave of AI systems. We focus on research that integrates in a principled way neural network-based learning with symbolic knowledge representation and logical reasoning. The insights provided by 20 years of neural-symbolic computing are shown to shed new light onto the increasingly prominent role of trust, safety, interpretability and accountability of AI. We also identify promising directions and challenges for the next decade of AI research from the perspective of neural-symbolic systems.


Neuro Symbolic Systems are Leading AI to the World of Imagination

#artificialintelligence

Neuro-symbolic systems, might recognize items using neural network pattern recognition and then uses symbolic AI reasoning to understand. Neuro-symbolic AI is a combination of neural networks and symbolic AI, which is more efficient than these two alone. It is a novel area of AI research that seeks to combine traditional rules-based AI approaches with modern deep learning techniques. Moreover, like a person, a neuro-symbolic system utilizes logic and language processing to answer the question. Symbolic AI refers to all steps on symbolic human-readable representations of the problem, solved using logic and search.
