An Intuitive Guide To Understanding The Learning Process Of A Neural Network

#artificialintelligence

Artificial neural networks are one of the most widely used methods in machine learning. And one of the most interesting things about a neural network is the way it learns about the data it's been trained on. It first starts by learning simple patterns in the data and then proceeds to learn more complex attributes. I decided to write this article after taking a class on neural networks and reading lots of articles about it. Even though I understood the structure of a neural network, and the process involved in adjusting the weights required to make proper predictions, it wasn't still clear to me why it worked the way it did. I wanted to be able to explain why and how the foremost layers in a network are able to discover simple attributes from a data set, and layers closer to the output layer can learn more complex attributes(which are combinations of attributes learnt from previous layers).


Dominant Strategy Equilibrium. The Evolution Of Choice Under Uncertainty. Analyze & Golden rules.

#artificialintelligence

Why Partnership Strategy, not Technology, drives Digital Transformation? Known from the 17th century (Blaise Pascal invoked it in his famous wager, which is contained in his Pensรฉes, published in 1670), the idea of expected value is that, when faced with a number of actions, each of which could give rise to more than one possible outcome with different probabilities, the rational procedure is to identify all possible outcomes, determine their values (positive or negative) and the probabilities that will result from each course of action, and multiply the two to give an "expected value", or the average expectation for an outcome; the action to be chosen should be the one that gives rise to the highest total expected value. Decision theory (or the theory of choice) is closely related to the field of game theory and is an interdisciplinary topic, studied by economists, statisticians, psychologists, biologists, political and other social scientists, philosophers, and computer scientists. The need for decision under uncertainty has never been stronger. Although the digital realm is evolving fast, the partnership strategical choice remains a human prerogative and a key driver of the digital ecosystem evolution.


How GO! is implementing AI in 700 Belgian schools

#artificialintelligence

Jan Buytaert is chief information officer at GO!, the public body for state schools in the Flanders region of Belgium. His role is to initiate new IT projects and prove their value to the business, with the hope that business decision makers and policymakers give them the green light. The projects can have huge implications for education in Belgium, as the region has around 750 schools and institutions, and 210,000 students. "There wasn't always a lot of digital innovation so I had to work hard trying to convince management and policymakers that we should invest in tech and digital education, and change the way of teaching and learning," Buytaert tells NS Tech. In 2016, Buytaert and his team analysed the way teaching was carried out in several schools, working alongside teachers, students and principals.



AI in education: A toxic mix of buzzwords and unqualified expertise?

#artificialintelligence

The UK government has developed a voracious appetite for artificial intelligence (AI), based on a promise of its apparently transformative power across myriad industries. From prime minister Boris Johnson's pledge to fund a ยฃ250m AI lab for the NHS, to the Department for Education's recently launched'AI horizon scanning group', AI is being lauded as a panacea to some of the most pressing issues society faces. Education is just one of the sectors that is meeting AI with open arms. As Matthew Jones at Perlego argued for this title, the opportunities being presented for AI to close educational accessibility gaps is exciting. In fact, educators, policymakers and investors are all being bombarded with messages related to AI's seemingly endless benefits in the classroom.


Fusing heterogeneous data sets

arXiv.org Machine Learning

In systems biology, it is common to measure biochemical entities at different levels of the same biological system. One of the central problems for the data fusion of such data sets is the heterogeneity of the data. This thesis discusses two types of heterogeneity. The first one is the type of data, such as metabolomics, proteomics and RNAseq data in genomics. These different omics data reflect the properties of the studied biological system from different perspectives. The second one is the type of scale, which indicates the measurements obtained at different scales, such as binary, ordinal, interval and ratio-scaled variables. In this thesis, we developed several statistical methods capable to fuse data sets of these two types of heterogeneity. The advantages of the proposed methods in comparison with other approaches are assessed using comprehensive simulations as well as the analysis of real biological data sets.


DAST Model: Deciding About Semantic Complexity of a Text

arXiv.org Artificial Intelligence

Measuring of text complexity is a needed task in several domains and applications (such as NLP, semantic web, smart education and etc.). The Semantic layer of a text is more tacit than its syntactic structure and as a result, calculation of semantic complexity is more difficult. Whereas there are famous and powerful academic and commercial syntactic complexity measures, the problem of measuring Semantic complexity is a challenging one, yet. In this article, we introduce the DAST model which stands for Deciding About Semantic Complexity of a Text. In this model, an intuitionistic approach to semantics lets us have a well-defined definition for semantic of a text and its complexity: we consider semantic and meaning as a lattice of intuitions. Semantic complexity is defined as the result of a calculation on this lattice. A set theoretic formal definition of semantic complexity, as a 6-tuple formal system, is provided. By using this formal system, a method for measuring semantic complexity is presented. The evaluation of the proposed approach is done by a detailed example and a case study, a set of eighteen human-judgment experiments and a corpus-based evaluation. The results show that DAST model is capable of deciding about semantic complexity of a text. Furthermore, Analysis of the experiment results leads us to introduce a Markovian model for the process of common-sense multi-steps semantic-complexity reasoning in people. The Experiments-result demonstrates that our method consistently outperforms the random baseline in terms of better precision and accuracy.


Interpretable Cognitive Diagnosis with Neural Network for Intelligent Educational Systems

arXiv.org Machine Learning

In intelligent education systems, one key issue is to discover students' proficiency level on specific knowledge concepts, which called cognitive diagnosis. Existing approaches usually mine the student exercising process by manually designed function, which is usually linear and not sufficient to capture complex relations between students and exercises. In this paper, we propose a general Neural Cognitive Diagnosis (NeuralCD) framework, which incorporates neural networks to learn the complex interactions between student's and exercise's factor vectors. The interpretability of factor vectors is guaranteed with the monotonicity assumption borrowed from educational psychology. We provide NeuralCDM model as an implementation example of the framework. Further, we explore the text content for improving NeuralCDM to show the extendability of NeuralCD, and demonstrate the generality of NeuralCD by proving how it covers some traditional diagnostic models. Extensive experimental results on real-world datasets show the effectiveness of NeuralCD framework with both accuracy and interpretability.
