Neurosymbolic Systems of Perception & Cognition: The Role of Attention

arXiv.org Artificial Intelligence

A cognitive architecture aimed at cumulative learning must provide the necessary information and control structures to allow agents to learn incrementally and autonomously from their experience. This involves managing an agent's goals as well as continuously relating sensory information to these in its perception-cognition information stack. The more varied the environment of a learning agent is, the more general and flexible must be these mechanisms to handle a wider variety of relevant patterns, tasks, and goal structures. While many researchers agree that information at different levels of abstraction likely differs in its makeup and structure and processing mechanisms, agreement on the particulars of such differences is not generally shared in the research community. A binary processing architecture (often referred to as System-1 and System-2) has been proposed as a model of cognitive processing for low- and high-level information, respectively. We posit that cognition is not binary in this way and that knowledge at any level of abstraction involves what we refer to as neurosymbolic information, meaning that data at both high and low levels must contain both symbolic and subsymbolic information. Further, we argue that the main differentiating factor between the processing of high and low levels of data abstraction can be largely attributed to the nature of the involved attention mechanisms. We describe the key arguments behind this view and review relevant evidence from the literature.

AI/ML-driven information systems are critical to today's multidisciplinary approach to improving healthcare outcomes, which includes sophisticated imaging and genetic-based tailored therapy models. Artificial Intelligence is basically a great evolution in the field of computer science. AI has changed the way of computing and carrying out tasks easier as well as automated. Artificial Intelligence is a way in which a machine learns about patterns and ways and by using its intelligence produces desired results.


How AI improves AML efforts across the financial services industry - Banking Exchange

#artificialintelligence

Money laundering and other types of financial crime have plagued the financial industry for years. Banks and other financial institutions have consistently found themselves one step behind criminals looking to take advantage of the holes within banks' security and monitoring systems and carry out criminal activity undetected. In response, many of these organizations have put in place anti-money laundering (AML) solutions. However, it's no secret that these systems still leave much to be desired. Attempting to stop money laundering without concern for accuracy can create real challenges.


Artificial intelligence reveals the secrets of the spider web - Digital Journal

#artificialintelligence

Despite years of in-depth study there is much still to learn about a spider's web, from the intricate patterns to the tensile strength and optoelectronic architectures. Webs are highly-complex structures, as with spider webs actively springing towards prey as the result of electrically-conductive glue spread across their surface. Webs also contain multiple silk types, with viscid silk (stretchy, wet and sticky) and dragline silk (stiff and dry) being responsible for the strength of the web. In a newly reported research topic, scientists from Johns Hopkins University have discovered how spiders build webs. This has been revealed through a combination of night vision and artificial intelligence.

It takes into consideration intelligent computer programs that can calculate, reason, learn from experience, adapt to new conditions, and handle complicated issues, to name a few examples.


US-Rule: Discovering Utility-driven Sequential Rules

arXiv.org Artificial Intelligence

Utility-driven mining is an important task in data science and has many applications in real life. High utility sequential pattern mining (HUSPM) is one kind of utility-driven mining. HUSPM aims to discover all sequential patterns with high utility. However, the existing algorithms of HUSPM can not provide an accurate probability to deal with some scenarios for prediction or recommendation. High-utility sequential rule mining (HUSRM) was proposed to discover all sequential rules with high utility and high confidence. There is only one algorithm proposed for HUSRM, which is not enough efficient. In this paper, we propose a faster algorithm, called US-Rule, to efficiently mine high-utility sequential rules. It utilizes rule estimated utility co-occurrence pruning strategy (REUCP) to avoid meaningless computation. To improve the efficiency on dense and long sequence datasets, four tighter upper bounds (LEEU, REEU, LERSU, RERSU) and their corresponding pruning strategies (LEEUP, REEUP, LERSUP, RERSUP) are proposed. Besides, US-Rule proposes rule estimated utility recomputing pruning strategy (REURP) to deal with sparse datasets. At last, a large number of experiments on different datasets compared to the state-of-the-art algorithm demonstrate that US-Rule can achieve better performance in terms of execution time, memory consumption and scalability.


Artificial Intelligence for Trading

#artificialintelligence

Artificial Intelligence is the behaviour or rules followed by or created by machines to imitate human or animal intelligence. There are several scenarios where one might use artificial intelligence for problem solving or various tasks. Artificial intelligence can be achieved through machine learning. Machine learning is the process of achieving artificial intelligence in a computer system either by supervision or learning itself. The 2 types of artificial intelligence are a rule-based model that simply follows instructions given to it and a machine learning model that trains on useful data first before predicting future results or solving problems.


Natural Language Processing in-and-for Design Research

arXiv.org Artificial Intelligence

We review the scholarly contributions that utilise Natural Language Processing (NLP) methods to support the design process. Using a heuristic approach, we collected 223 articles published in 32 journals and within the period 1991-present. We present state-of-the-art NLP in-and-for design research by reviewing these articles according to the type of natural language text sources: internal reports, design concepts, discourse transcripts, technical publications, consumer opinions, and others. Upon summarizing and identifying the gaps in these contributions, we utilise an existing design innovation framework to identify the applications that are currently being supported by NLP. We then propose a few methodological and theoretical directions for future NLP in-and-for design research.


Efficient Decompositional Rule Extraction for Deep Neural Networks

arXiv.org Artificial Intelligence

In recent years, there has been significant work on increasing both interpretability and debuggability of a Deep Neural Network (DNN) by extracting a rule-based model that approximates its decision boundary. Nevertheless, current DNN rule extraction methods that consider a DNN's latent space when extracting rules, known as decompositional algorithms, are either restricted to single-layer DNNs or intractable as the size of the DNN or data grows. In this paper, we address these limitations by introducing ECLAIRE, a novel polynomial-time rule extraction algorithm capable of scaling to both large DNN architectures and large training datasets. We evaluate ECLAIRE on a wide variety of tasks, ranging from breast cancer prognosis to particle detection, and show that it consistently extracts more accurate and comprehensible rule sets than the current state-of-the-art methods while using orders of magnitude less computational resources.


Voice-only telehealth might go away with pandemic rules set to expire

NPR Technology

Community clinics say the easing of restrictions on telehealth during the pandemic has made it possible for health workers to connect with hard-to-reach patients via a phone call -- people who are poor, elderly or live in remote areas, and don't have access to a computer or cell phone with video capability. Community clinics say the easing of restrictions on telehealth during the pandemic has made it possible for health workers to connect with hard-to-reach patients via a phone call -- people who are poor, elderly or live in remote areas, and don't have access to a computer or cell phone with video capability. Caswell County, where William Crumpton works, runs along the northern edge of North Carolina and is a rural landscape of mostly former tobacco farms and the occasional fast-food restaurant. "There are wide areas where cell phone signals are just nonexistent," Crumpton says. "Things like satellite radio are even a challenge."
