Why Talent Shortage In AI May End Soon
Organisations across the world are witnessing talent shortage in AI and are struggling to hire competent employees in this ever-changing landscape. Since every company is striving for a data-driven approach, there is a rise in the integration of technologies such as artificial intelligence, data science, among others, to achieve business objectives. However, the absence of superior talent in the market is impeding the growth of firms. In fact, research tells us that 85% of AI projects fail due to risk, confusion and lack of upskilling in the employees. "It is very challenging to get excellent developers in the space even though AI and Data Science has been the most sought-after skill," says Gaurav Mehrotra, vice president and head of business data solutions at Innoviti Payment Solutions. A recent report published by noted online learning platform Coursera states that out of the 45 million learners on the platform, two million enrolled in AI-based content in 2019.
Analyzing Privacy Loss in Updates of Natural Language Models
Tople, Shruti, Brockschmidt, Marc, Köpf, Boris, Ohrimenko, Olga, Zanella-Béguelin, Santiago
To continuously improve quality and reflect changes in data, machine learning-based services have to regularly re-train and update their core models. In the setting of language models, we show that a comparative analysis of model snapshots before and after an update can reveal a surprising amount of detailed information about the changes in the data used for training before and after the update. We discuss the privacy implications of our findings, propose mitigation strategies and evaluate their effect.
Causality matters in medical imaging
Castro, Daniel C., Walker, Ian, Glocker, Ben
This article discusses how the language of causality can shed new light on the major challenges in machine learning for medical imaging: 1) data scarcity, which is the limited availability of high-quality annotations, and 2) data mismatch, whereby a trained algorithm may fail to generalize in clinical practice. Looking at these challenges through the lens of causality allows decisions about data collection, annotation procedures, and learning strategies to be made (and scrutinized) more transparently. We discuss how causal relationships between images and annotations can not only have profound effects on the performance of predictive models, but may even dictate which learning strategies should be considered in the first place. For example, we conclude that semi-supervision may be unsuitable for image segmentation---one of the possibly surprising insights from our causal analysis, which is illustrated with representative real-world examples of computer-aided diagnosis (skin lesion classification in dermatology) and radiotherapy (automated contouring of tumours). We highlight that being aware of and accounting for the causal relationships in medical imaging data is important for the safe development of machine learning and essential for regulation and responsible reporting. To facilitate this we provide step-by-step recommendations for future studies.

Gartner Says Nearly Half of CIOs Are Planning to Deploy Artificial Intelligence
Meaningful artificial intelligence (AI) deployments are just beginning to take place, according to Gartner, Inc. Gartner's 2018 CIO Agenda Survey shows that four percent of CIOs have implemented AI, while a further 46 percent have developed plans to do so. "Despite huge levels of interest in AI technologies, current implementations remain at quite low levels," said Whit Andrews, research vice president and distinguished analyst at Gartner. "However, there is potential for strong growth as CIOs begin piloting AI programs through a combination of buy, build and outsource efforts." As with most emerging or unfamiliar technologies, early adopters are facing many obstacles to the progress of AI in their organizations. Gartner analysts have identified the following four lessons that have emerged from these early AI projects.
Could artificial intelligence help to save our planet?
According to a new Forum-PwC report, released in Davos, Switzerland, there are eight ways in which artificial intelligence (AI) can help save the planet. The first being the use of autonomous and connected electric vehicles, as the technology will catalyse the transition to mobility on-demand. Through route and traffic optimisation, eco-driving algorithms, the programmed platooning of cars to traffic, and ride-sharing systems, transportation could contribute significantly less to greenhouse gas emissions. With distributed energy grids, AI could perfect the predictability of demand – and in turn supply – for renewable energy. This could amplify energy storage, efficiency, and load management, whilst also integrating renewables for better pricing for market incentives.

Classifying Inconsistency Measures Using Graphs
De Bona, Glauber, Grant, John, Hunter, Anthony, Konieczny, Sebastien
The aim of measuring inconsistency is to obtain an evaluation of the imperfections in a set of formulas, and this evaluation may then be used to help decide on some course of action (such as rejecting some of the formulas, resolving the inconsistency, seeking better sources of information, etc). A number of proposals have been made to define measures of inconsistency. Each has its rationale. But to date, it is not clear how to delineate the space of options for measures, nor is it clear how we can classify measures systematically. To address these problems, we introduce a general framework for comparing syntactic measures of inconsistency. It is based on the notion of an inconsistency graph for each knowledgebase (a bipartite graph with a set of vertices representing formulas in the knowledgebase, a set of vertices representing minimal inconsistent subsets of the knowledgebase, and edges representing that a formula belongs to a minimal inconsistent subset). We then show that various measures can be computed using the inconsistency graph. Then we introduce abstractions of the inconsistency graph and use them to construct a hierarchy of syntactic inconsistency measures. Furthermore, we extend the inconsistency graph concept with a labeling that extends the hierarchy to include some other types of inconsistency measures.
Efficient adjustment sets for population average treatment effect estimation in non-parametric causal graphical models
Rotnitzky, Andrea, Smucler, Ezequiel
The method of covariate adjustment is often used for estimation of population average treatment effects in observational studies. Graphical rules for determining all valid covariate adjustment sets from an assumed causal graphical model are well known. Restricting attention to causal linear models, a recent article derived two novel graphical criteria: one to compare the asymptotic variance of linear regression treatment effect estimators that control for certain distinct adjustment sets and another to identify the optimal adjustment set that yields the least squares treatment effect estimator with the smallest asymptotic variance among consistent adjusted least squares estimators. In this paper we show that the same graphical criteria can be used in non-parametric causal graphical models when treatment effects are estimated by contrasts involving non-parametrically adjusted estimators of the interventional means. We also provide a graphical criterion for determining the optimal adjustment set among the minimal adjustment sets, which is valid for both linear and non-parametric estimators. We provide a new graphical criterion for comparing time dependent adjustment sets, that is, sets comprised by covariates that adjust for future treatments and that are themselves affected by earlier treatments. We show by example that uniformly optimal time dependent adjustment sets do not always exist. In addition, for point interventions, we provide a sound and complete graphical criterion for determining when a non-parametric optimally adjusted estimator of an interventional mean, or of a contrast of interventional means, is as efficient as an efficient estimator of the same parameter that exploits the information in the conditional independencies encoded in the non-parametric causal graphical model.
STConvS2S: Spatiotemporal Convolutional Sequence to Sequence Network for Weather Forecasting
Nascimento, Rafaela C., Souto, Yania M., Ogasawara, Eduardo, Porto, Fabio, Bezerra, Eduardo
Applying machine learning models to meteorological data brings many opportunities to the Geosciences field, such as predicting future weather conditions more accurately. In recent years, modeling meteorological data with deep neural networks has become a relevant area of investigation. These works apply either recurrent neural networks (RNNs) or some hybrid approach mixing RNNs and convolutional neural networks (CNNs). In this work, we propose STConvS2S (short for Spatiotemporal Convolutional Sequence to Sequence Network), a new deep learning architecture built for learning both spatial and temporal data dependencies in weather data, using fully convolutional layers. Computational experiments using observations of air temperature and rainfall show that our architecture captures spatiotemporal context and outperforms baseline models and the state-of-art architecture for weather forecasting task.
