ANN-based Shear Capacity of Steel Fiber-Reinforced Concrete Beams Without Stirrups

Authors: M. Abambres, E. Lantsoght
Comments: 24 Pages.

Comparing experimental results on the shear capacity of steel fiber-reinforced concrete (SFRC) beams without mild steel stirrups, to the ones predicted by current design equations and other available formulations, still shows significant differences. In this paper we propose the use of artificial intelligence to estimate the shear capacity of these members. A database of 430 test results reported in the literature is used to develop an artificial neural network-based formula that predicts the shear capacity of SFRC beams without shear reinforcement. The proposed model yields maximum and mean relative errors of 0.0% for the 430 data points, which represents a better prediction (mean Vtest / VANN = 1.00 with a coefficient of variation of 1× 10-15) than the existing expressions, where the best model yields a mean value of Vtest / Vpred = 1.01 and a coefficient of variation of 27%.

Brain-Computer Interfaces

Authors: George Rajna
Comments: 28 Pages.

It sounds like science fiction: controlling electronic devices with brain waves. But researchers have developed a new type of electroencephalogram (EEG) electrode that can do just that, without the sticky gel required for conventional electrodes. [19] U.S. Army Research Laboratory scientists have discovered a way to leverage emerging brain-like computer architectures for an age-old number-theoretic problem known as integer factorization. [18] Now researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have come up with a novel machine learning method that enables scientists to derive insights from systems of previously intractable complexity in record time.

Unboxing ai Radiological Insights Into a Deep Neural Network for Lung Nodule Characterization

Authors: Vasantha Kumar Venugopal
Comments: 18 Pages.

Rationale and Objectives: To explain predictions of a deep residual convolutional network for characterization of lung nodule by analyzing heat maps Materials and Methods A 20-layer deep residual CNN was trained on 1245 Chest CTs from NLST trial to predict the malignancy risk of a nodule. We used occlusion to systematically block regions of a nodule and map drops in the malignancy-risk score to generate clinical attribution heatmaps on 103 nodules from LIDC-IDRI dataset, which were analyzed by a thoracic radiologist. The features were described as heat inside nodule (IH)-bright areas inside nodule, peripheral heat (PH)-continuous/interrupted bright areas along nodule contours, heat in adjacent plane (AH)-brightness in scan planes juxtaposed with the nodule, satellite heat (SH)- a smaller bright spot in proximity to nodule in the same scan plane, heat map larger than nodule (LH)-bright areas corresponding to the shape of the nodule seen outside the nodule margins and heat in calcification (CH) Results These six features were assigned binary values. This feature vector was fed into a standard J48 decision tree with 10-fold cross-validation, which gave an 85 % weighted classification accuracy with a 77.8 %TP rate, 8% FP rate for benign cases and 91.8% TP and 22.2 %FP rates for malignant cases. IH was more frequently observed in nodules classified as malignant whereas PH, AH, and SH were more commonly seen in nodules classified as benign. Conclusion We discuss the potential ability of a radiologist to visually parse the deep learning algorithm-generated 'heat map' to identify features aiding classification

Artificial Intelligence Probes Dark Matter

Authors: George Rajna
Comments: 52 Pages.

A team of physicists and computer scientists at ETH Zurich has developed a new approach to the problem of dark matter and dark energy in the universe. Using machine learning tools, they programmed computers to teach themselves how to extract the relevant information from maps of the universe. [31] These results, important for the construction of new theoretical models and for the development of new hypotheses about the nature of dark matter, offer much more precise indications for tracing the intricate path to understanding one of the largest mysteries of the cosmos. [30] New research lends further support to the idea that a detection of surprisingly strong absorption by primordial hydrogen gas, reported earlier this year, could be evidence of dark matter. [29] Physicists in Italy are about to start up a new experiment designed to hunt for hypothetical particles such as the "dark photon" and carriers of a possible fifth force of nature. [28] A signal caused by the very first stars to form in the universe has been picked up by a tiny but highly specialised radio telescope in the remote Western Australian desert. [27] This week, scientists from around the world who gathered at the University of California, Los Angeles, at the Dark Matter 2018 Symposium learned of new results in the search for evidence of the elusive material in Weakly Interacting Massive Particles (WIMPs) by the DarkSide-50 detector. [26] If they exist, axions, among the candidates for dark matter particles, could interact with the matter comprising the universe, but at a much weaker extent than previously theorized. New, rigorous constraints on the properties of axions have been proposed by an international team of scientists. [25] The intensive, worldwide search for dark matter, the missing mass in the universe, has so far failed to find an abundance of dark, massive stars or scads of strange new weakly interacting particles, but a new candidate is slowly gaining followers and observational support.

Application of ANN in Pavement Engineering: State-of-Art

Authors: M. Abambres, A. Ferreira
Comments: 61 Pages.

There has been much discussion about the impact and future of artificial intelligence (AI) in our lives and future generations. Many experts even believe that AI will “rule” the world. Artificial Neural Networks (ANN) have provided a convenient and often extremely accurate solution to problems within all fields, and can be seen as advanced general-purpose regression models that try to mimic the behavior of the human brain. The adoption and use of ANN-based methods in the Mechanistic-Empirical Pavement Design Guide is a clear sign of the successful use of neural nets in geomechanical and pavement systems. This work aims to provide an extensive and detailed state-of-the-art of the application of ANN models to pavement management, materials and design problems. Unlike former review articles published before 2014, this work is more descriptive and makes the review much more appealing to the reader by highlighting numerically and/or graphically the effectiveness and possible drawbacks of each ANN application.

Neural Network-Based Formula for the Buckling Load Prediction of I-Section Cellular Steel Beams

Authors: M. Abambres, K. Rajana, K. Tsavdaridis, T. Ribeiro
Comments: 50 Pages.

Cellular beams are an attractive option for the steel construction industry due to their versatility in terms of strength, size, and weight. Further benefits are the integration of services thereby reducing ceiling-to-floor depth (thus, building’s height), which has a great economic impact. Moreover, the complex localised and global failures characterizing those members have led several scientists to focus their research on the development of more efficient design guidelines. This paper aims to propose an artificial neural network (ANN)-based formula to estimate the critical elastic buckling load of simply supported cellular beams under uniformly distributed vertical loads. The 3645-point dataset used in ANN design was obtained from an extensive parametric finite element analysis performed in ABAQUS. The independent variables adopted as ANN inputs are the following: beam’s length, opening diameter, web-post width, cross-section height, web thickness, flange width, flange thickness, and the distance between the last opening edge and the end support. The proposed model shows a strong potential as an effective design tool. The maximum and average relative errors among the 3645 data points were found to be 3.7% and 0.4%, respectively, whereas the average computing time per data point is smaller than a millisecond for any current personal computer.

Neural Network-Based Analytical Model to Predict the Shear Strength of Steel Girders with a Trapezoidal Corrugated Web

Authors: M. Abambres, J. He
Comments: 31 Pages.

Corrugated webs are used to increase the shear stability of steel webs of beam-like members and to eliminate the need of transverse stiffeners. Previously developed formulas for predicting the shear strength of trapezoidal corrugated steel webs, along with the corresponding theory, are summarized. An artificial neural network (ANN)-based model is proposed to estimate the shear strength of steel girders with a trapezoidal corrugated web, and under a concentrated load. 210 test results from previous published research were collected into a database according to relevant test specimen parameters in order to feed the simulated ANNs. Seven (geometrical and material) parameters were identified as input variables and the ultimate shear stress at failure was considered the output variable. The proposed ANN-based analytical model yielded maximum and mean relative errors of 0.0% for the 210 points from the database. Moreover, still based on those points, it was illustrated that the ANN-based model clearly outperforms the other existing analytical models, which yield mean errors larger than 13%.

Shear Capacity of Headed Studs in Steel-Concrete Structures: Analytical Prediction via Soft Computing

Authors: M. Abambres, J. He
Comments: 29 Pages.

Headed studs are commonly used as shear connectors to transfer longitudinal shear force at the interface between steel and concrete in composite structures (e.g., bridge decks). Code-based equations for predicting the shear capacity of headed studs are summarized. An artificial neural network (ANN)-based analytical model is proposed to estimate the shear capacity of headed steel studs. 234 push-out test results from previous published research were collected into a database in order to feed the simulated ANNs. Three parameters were identified as input variables for the prediction of the headed stud shear force at failure, namely the steel stud tensile strength and diameter, and the concrete (cylinder) compressive strength. The proposed ANN-based analytical model yielded, for all collected data, maximum and mean relative errors of 3.3 % and 0.6 %, respectively. Moreover, it was illustrated that, for that data, the neural network approach clearly outperforms the existing code-based equations, which yield mean errors greater than 13 %.

Neural Network-Based Formula for Shear Capacity Prediction of One-Way Slabs Under Concentrated Loads

Authors: M. Abambres, E. Lantsoght
Comments: 33 Pages.

According to the current codes and guidelines, shear assessment of existing reinforced concrete slab bridges sometimes leads to the conclusion that the bridge under consideration has insufficient shear capacity. The calculated shear capacity, however, does not consider the transverse redistribution capacity of slabs, thus leading to overconservative values. This paper proposes an artificial neural network (ANN)-based formula to come up with estimates of the shear capacity of one-way reinforced concrete slabs under a concentrated load, based on 287 test results gathered from the literature. The proposed model yields maximum and mean relative errors of 0.0% for the 287 data points. Moreover, it was illustrated to clearly outperform (mean Vtest / VANN =1.00) the Eurocode 2 provisions (mean VE,EC / VR,c =1.59) for that dataset. A step-by-step assessment scheme for reinforced concrete slab bridges by means of the ANN-based model is also proposed, which results in an improvement of the current assessment procedures.

Potential of Neural Networks for Maximum Displacement Predictions in Railway Beams on Frictionally Damped Foundations

Authors: M. Abambres, R. Corrêa, A. Pinto da Costa, F. Simões
Comments: 63 Pages.

Since the use of finite element (FE) simulations for the dynamic analysis of railway beams on frictionally damped foundations are (i) very time consuming, and (ii) require advanced know-how and software that go beyond the available resources of typical civil engineering firms, this paper aims to demonstrate the potential of Artificial Neural Networks (ANN) to effectively predict the maximum displacements and the critical velocity in railway beams under moving loads. Four ANN-based models are proposed, one per load velocity range ([50, 175] ∪ [250, 300] m/s; ]175, 250[ m/s) and per displacement type (upward or downward). Each model is function of two independent variables, a frictional parameter and the load velocity. Among all models and the 663 data points used, a maximum error of 5.4 % was obtained when comparing the ANN- and FE-based solutions. Whereas the latter involves an average computing time per data point of thousands of seconds, the former does not even need a millisecond. This study was an important step towards the development of more versatile (i.e., including other types of input variables) ANN-based models for the same type of problem.

Potential of Neural Networks for Structural Damage Localization

Authors: M. Abambres, M. Marcy, G. Doz
Comments: Pages.

Fabrication technology and structural engineering states-of-art have led to a growing use of slender structures, making them more susceptible to static and dynamic actions that may lead to some sort of damage. In this context, regular inspections and evaluations are necessary to detect and predict structural damage and establish maintenance actions able to guarantee structural safety and durability with minimal cost. However, these procedures are traditionally quite time-consuming and costly, and techniques allowing a more effective damage detection are necessary. This paper assesses the potential of Artificial Neural Network (ANN) models in the prediction of damage localization in structural members, as function of their dynamic properties – the three first natural frequencies are used. Based on 64 numerical examples from damaged (mostly) and undamaged steel channel beams, an ANN-based analytical model is proposed as a highly accurate and efficient damage localization estimator. The proposed model yielded maximum errors of 0.2 and 0.7 % concerning 64 numerical and 3 experimental data points, respectively. Due to the high-quality of results, authors’ next step is the application of similar approaches to entire structures, based on much larger datasets.

Machine Learning Rewilding

Authors: George Rajna
Comments: 32 Pages.

There may not be an obvious connection between rewilding and machine learning, but as highlighted today at ESA's ɸ-week, a project in the Netherlands uses satellite data and new digital technology to understand how a nature reserve responds to the pressure of being grazed by herbivores. [22] At the University of South Florida, researchers are integrating machine learning techniques into their work studying proteins. [21] Bioinformatics professors Anthony Gitter and Casey Greene set out in summer 2016 to write a paper about biomedical applications for deep learning, a hot new artificial intelligence field striving to mimic the neural networks of the human brain. [20] A team of researchers from the University of Muenster in Germany has now demonstrated that this combination is extremely well suited to planning chemical syntheses-so-called retrosyntheses-with unprecedented efficiency. [19] Two physicists at ETH Zurich and the Hebrew University of Jerusalem have developed a novel machine-learning algorithm that analyses large data sets describing a physical system and extract from them the essential information needed to understand the underlying physics.

The Algorithmic Audit: Working with Vendors to Validate Radiology-AI Algorithms - How We Do It

Authors: Vidur Mahajan, Vasanthakumar Venugopal, Saumya Gaur, Salil Gupta, Murali Murugavel, Harsh Mahajan
Comments: 7 Pages.

There is a plethora of Artificial Intelligence (AI) tools that are being developed around the world aiming at either speeding up or improving the accuracy of radiologists. It is essential for radiologists to work with the developers of such algorithms to determine true clinical utility and risks associated with these algorithms. We present a framework, called an Algorithmic Audit, for working with the developers of such algorithms to test and improve the performance of the algorithms. The framework includes concepts of true independent validation on data that the algorithm has not seen before, curating datasets for such testing, deep examination of false positives and false negatives (to examine implications of such errors) and real-world deployment and testing of algorithms.

Multi-Dimensional Asset Allocation Strategy with DA-RNN

Authors: Tae Young Lee
Comments: 7 Pages. Draft Paper

Most RoboAdvisors reflect the perspective of investment banks, which differs from commercial banks in Korea. Most customers who use commercial banks have a conservative approach. In customer-focused thinking, the more you design your Robo Advisor, the more important it is to minimize customer losses. It was designed with the belief that the guarantee of principal through defense of the bear market would be a solid foundation to be returned to profits from the bear market. The traditional asset allocation model is dedicated to simple predictions that take risk as a parameter of volatility and draw the expected return to calculate the optimal share of the asset. This is not a big problem when the market is good, but it's going to cause a loss of the customer's principal in a booming market. This is not in line with the bank's robovisor idea, and we have created deep learning algorithms to defend against the bear market.

Trimming Neural Networks

Authors: Mastane Achab, Massil Achab
Comments: 3 Pages.

We introduce a new type of artificial neural network (ANN): the trimming neural network (TNN) model. As most ANNs, a TNN is an alternating sequence of linear and nonlinear vectorial operators. Recall that in usual ANN models, nonlinear functions are independently applied on each entry of each layer. In contrast, we design TNNs' nonlinearities as functions of the whole layer: indeed, they are based on sorting all the layer's entries. In particular, we focus on the trimming operation which consists in summing all entries but a certain fraction of the smallest/largest ones. We show that TNNs enjoy convexity properties useful in various statistical learning contexts.

Deep Reinforcement Learning for Visual Question Answering

Authors: Ayoub Abraich
Comments: 131 Pages.

La conception de bout en bout des systèmes de dialogue est récemment devenue un sujet de recherche populaire grâce à des outils puissants tels que des architectures codeur-décodeur pour l'apprentissage séquence à séquence. Pourtant, la plupart des approches actuelles considèrent la gestion du dialogue homme-machine comme un problème d’apprentissage supervisé, visant à prédire la prochaine déclaration d’un participant, compte tenu de l’historique complet du dialogue. Cette vision est aussi simpliste pour rendre le problème de planification intrinsèque inhérent au dialogue ainsi que sa nature enracinée, rendant le contexte d'un dialogue plus vaste que seulement l'historique. C’est la raison pour laquelle seules les tâches de bavardage et de réponse aux questions ont été traitées jusqu’à présent en utilisant des architectures de bout en bout. Dans ce rapport, nous présentons une méthode d’apprentissage par renforcement profond permettant d’optimiser les dialogues axés sur les tâches, basés sur l’algorithme policy gradient. Cette approche est testée sur un ensemble de données de 120 000 dialogues collectés via Mechanical Turk et fournit des résultats encourageants pour résoudre à la fois le problème de la génération de dialogues naturels et la tâche de découvrir un objet spécifique dans une image complexe.

StarGAN has shown excellent performance in image-to-image translation using adversarial, reconstruction, and classification losses in multi-domain image-to-image translation. The Style-Based Generator Architecture boosts generator performance through the Embedder and AdaIn modules. I propose here an attribute loss, which is like having multiple GANs, which is enhanced by combining StarGAN's conditional GAN loss (adversarial loss and classification loss) to improve learning speed. And suggest the new generator architecture, whose name is bi-directional progressive growing Style-Based U-Net generator, to improve learning speed.

The Neural Qubit & Quantum Deep Learning

Authors: Siraj Raval
Comments: 10 Pages.

Deep learning has resulted in state of the art performance for automated tasks in the fields of natural language processing, computer vision, autonomous driving, and many other subfields of Artificial Intelligence. However, if the goal is to create a system that is capable of learning any task, given an objective function, I hypothesize that it’s necessary to reconsider classical neural network architecture to incorporate certain properties of quantum mechanics, namely superposition and entanglement. Building on the work of Fisher [12], I surmise that Phosphorus-31 enables both of these properties to occur within neurons in the human brain. In light of this evidence, quantum information processing in the context of digital neural networks is an area that deserves further exploration. As such, I present a novel quantum neural network architecture, similar to the continuous variable archicecture by Killoran et al. [11]. It was applied to a transaction dataset for a fraud detection task and attained a considerable accuracy score. My aim is that this will provide a starting point for more research in this space, ultimately using this technology to drive more innovation in every Scientific discipline, from Pharmacology to Computer Science.
