A new industrial revolution is taking place now and AI (AI) is transforming countries economically. The answer to the question of who is ahead and who is behind is determined by the new economic model based on this AI. Dozens of countries, from China to the U.S., from Finland to Kenya, are making significant investments in the area. It should be noted that by 2030, AI studies will generate a gross domestic product (GDP) greater than the current size of the Chinese economy ($15 trillion). From this new economy, China will generate nearly $7 trillion, the U.S. $3.7 trillion, Northern Europe $1.8 trillion, Africa-Oceania $1.2 trillion, the rest of Asia $0.9 trillion and Latin America $0.5 trillion.

Recently, generative adversarial networks (GANs), which learn data distributions through adversarial training, have gained special attention owing to their high image reproduction ability. However, one limitation of standard GANs is that they recreate training images faithfully despite image degradation characteristics such as blur, noise, and compression. To remedy this, we address the problem of blur, noise, and compression robust image generation. Our objective is to learn a non-degraded image generator directly from degraded images without prior knowledge of image degradation. The recently proposed noise robust GAN (NR-GAN) already provides a solution to the problem of noise degradation. Therefore, we first focus on blur and compression degradations. We propose blur robust GAN (BR-GAN) and compression robust GAN (CR-GAN), which learn a kernel generator and quality factor generator, respectively, with non-degraded image generators. Owing to the irreversible blur and compression characteristics, adjusting their strengths is non-trivial. Therefore, we incorporate switching architectures that can adapt the strengths in a data-driven manner. Based on BR-GAN, NR-GAN, and CR-GAN, we further propose blur, noise, and compression robust GAN (BNCR-GAN), which unifies these three models into a single model with additionally introduced adaptive consistency losses that suppress the uncertainty caused by the combination. We provide benchmark scores through large-scale comparative studies on CIFAR-10 and a generality analysis on FFHQ dataset.

In ontology-mediated querying, description logic (DL) ontologies are used to enrich incomplete data with domain knowledge which results in more complete answers to queries. However, the evaluation of ontology-mediated queries (OMQs) over relational databases is computationally hard. This raises the question when OMQ evaluation is efficient, in the sense of being tractable in combined complexity or fixed-parameter tractable. We study this question for a range of ontology-mediated query languages based on several important and widely-used DLs, using unions of conjunctive queries as the actual queries. For the DL ELHI extended with the bottom concept, we provide a characterization of the classes of OMQs that are fixed-parameter tractable. For its fragment EL extended with domain and range restrictions and the bottom concept (which restricts the use of inverse roles), we provide a characterization of the classes of OMQs that are tractable in combined complexity. Both results are in terms of equivalence to OMQs of bounded tree width and rest on a reasonable assumption from parameterized complexity theory. They are similar in spirit to Grohe's seminal characterization of the tractable classes of conjunctive queries over relational databases. We further study the complexity of the meta problem of deciding whether a given OMQ is equivalent to an OMQ of bounded tree width, providing several completeness results that range from NP to 2ExpTime, depending on the DL used. We also consider the DL-Lite family of DLs, including members that admit functional roles.

Physiological signals, such as the electrocardiogram and the phonocardiogram are very often corrupted by noisy sources. Usually, artificial intelligent algorithms analyze the signal regardless of its quality. On the other hand, physicians use a completely orthogonal strategy. They do not assess the entire recording, instead they search for a segment where the fundamental and abnormal waves are easily detected, and only then a prognostic is attempted. Inspired by this fact, a new algorithm that automatically selects an optimal segment for a post-processing stage, according to a criteria defined by the user is proposed. In the process, a Neural Network is used to compute the output state probability distribution for each sample. Using the aforementioned quantities, a graph is designed, whereas state transition constraints are physically imposed into the graph and a set of constraints are used to retrieve a subset of the recording that maximizes the likelihood function, proposed by the user. The developed framework is tested and validated in two applications. In both cases, the system performance is boosted significantly, e.g in heart sound segmentation, sensitivity increases 2.4% when compared to the standard approaches in the literature.

Many machine learning problems consider data where each instance is, itself, an unordered set of elements; i.e., such that each observation is a set. Data of this kind arises in a variety of applications, ranging from document modeling (Blei et al., 2003; Garnelo et al., 2018a) and multi-task learning (Zaheer et al., 2017; Edwards & Storkey, 2016; Liu et al., 2019) to 3D point cloud modeling (Li et al., 2018; Yang et al., 2019). In unsupervised settings, a dataset typically consists of a set of such sets, while in supervised learning, it consists of a set of (set, label) pairs. Modeling a distribution over a space of instances, where each instance is, itself, an unordered set of elements involves two key considerations: (1) the elements within a single instance are exchangeable, i.e., the elements are order invariant; and (2) the cardinalities of the instances (sets) vary, i.e., instances need not exhibit the same cardinality. Modeling both unconditional and conditional distributions over instances (sets) are relevant to consider, since these support unsupervised and supervised tasks respectively. For unconditional distribution modeling, there has been significant prior work on modeling set distributions, which has sought to balance competing needs to expand model flexibility and preserve tractability on the one hand, with respecting exchangeability and varying instance cardinalities on the other hand. However, managing these tradeoffs has proved to be quite difficult, and current approaches remain limited in different respects. For example, a particularly straightforward strategy for modeling distributions over instances x {x 1,..., x n } without assuming fixed cardinality is simply to use a recurrent neural network (RNNs) to encode instance probability auto-regressively via p (x) n

This paper presents a software implementation of a general framework for time series interpretation based on abductive reasoning. The software provides a data model and a set of algorithms to make inference to the best explanation of a time series, resulting in a description in multiple abstraction levels of the processes underlying the time series. As a proof of concept, a comprehensive knowledge base for the electrocardiogram (ECG) domain is provided, so it can be used directly as a tool for ECG analysis. This tool has been successfully validated in several noteworthy problems, such as heartbeat classification or atrial fibrillation detection.

Centralized state camera surveillance is but one component of a burgeoning practice of personal data collection paired with artificial intelligence (AI). Camera surveillance is not inherently unlawful and has long been used at border-crossings, airports, and other high-security areas. However, recent technological advances have contributed to the spread of a more intrusive form of video surveillance that includes powerful, if imperfect, facial recognition abilities and AI decision making. While the technology offers states the ability to, among other things, identify lost children, identify criminals, and monitor threats, the new capacity also raises significant human rights issues. The use of camera surveillance has grown with leaps in technology, including the introduction of videocassette recorders in the 1970s and the internet in the 1990s.

This paper plays a part in two branches of the asset pricing literature, the multi-factor literature built on the Arbitrage Pricing Theory (APT) from Ross (1976) [1] and the Inter-temporal Capital Asset Pricing Model (ICAPM) from Merton (1973) [2] and to the growing literature related to the low-risk anomaly. First, we use the Adaptive Multi-Factor (AMF) model framework developed in Zhu et al. (2018) [3] in which both the APT and ICAPM are special cases under weaker conditions with three main added benefits: 1) It allows for a large number of risk factors to explain returns even though empirically a smaller subset of them is needed to explain returns, 2) The set of risk factors is different for different securities, and 3) The risk factors are Exchange Traded Funds (ETF) which are tradeable instruments. Second, the low-risk anomaly is an empirical asset pricing observation in which stocks with lower risk yield higher returns than stocks with higher risk. The two main measures for characterising risk in this context are volatility of returns and β derived from the Capital Asset Pricing Model (CAPM). Therefore, when mentioning the low-risk anomaly, we are referring to the low-volatility and the low-beta anomaly interchangeably.
