Chatbots Should Be An Abstraction Of Human Conversation
When creating or rather crafting a chatbot conversation we as designers must draw inspiration and guidance from real-world conversations. Elements of human conversation should be identified and abstracted to be incorporated in our chatbot conversation. General rules and concepts of human conversations must be derived and implemented via technically astute means. Below I list 10 elements of human conversation which can be incorporated in a Conversational AI interface. Conversational designers want users to speak to their chatbot as to a human…hence it is time for the chatbot to converse more human like. Christoph Niemann has fascinating ideas on abstraction and when visual design becomes too abstract. The speaker introduces a topic, subsequently the speaker introduces a second topic, another story that seems to be unrelated.
Data labeling industry
Artificial General Intelligence (AGI) is at the core of a vision that leads the future of our world. Its main goal is to provide autonomous solutions for each mankind's problem, a fully automated system that will serve humans and live among them. Artificial Intelligence is the technology to fulfill such a vision. At the intersection of computer science and data science, AI's first step is to create a computational representation of everything. Algorithms & Big Data are the two keys.
Measuring agreement on linguistic expressions in medical treatment scenarios
Navrro, J, Wagner, C, Aickelin, Uwe, Green, L, Ashford, R
Quality of life assessment represents a key process of deciding treatment success and viability. As such, patients' perceptions of their functional status and well-being are important inputs for impairment assessment. Given that patient completed questionnaires are often used to assess patient status and determine future treatment options, it is important to know the level of agreement of the words used by patients and different groups of medical professionals. In this paper, we propose a measure called the Agreement Ratio which provides a ratio of overall agreement when modelling words through Fuzzy Sets (FSs). The measure has been specifically designed for assessing this agreement in fuzzy sets which are generated from data such as patient responses. The measure relies on using the Jaccard Similarity Measure for comparing the different levels of agreement in the FSs generated.
FAIR: Fair Adversarial Instance Re-weighting
Petrović, Andrija, Nikolić, Mladen, Radovanović, Sandro, Delibašić, Boris, Jovanović, Miloš
With growing awareness of societal impact of artificial intelligence, fairness has become an important aspect of machine learning algorithms. The issue is that human biases towards certain groups of population, defined by sensitive features like race and gender, are introduced to the training data through data collection and labeling. Two important directions of fairness ensuring research have focused on (i) instance weighting in order to decrease the impact of more biased instances and (ii) adversarial training in order to construct data representations informative of the target variable, but uninformative of the sensitive attributes. In this paper we propose a Fair Adversarial Instance Re-weighting (FAIR) method, which uses adversarial training to learn instance weighting function that ensures fair predictions. Merging the two paradigms, it inherits desirable properties from both -- interpretability of reweighting and end-to-end trainability of adversarial training. We propose four different variants of the method and, among other things, demonstrate how the method can be cast in a fully probabilistic framework. Additionally, theoretical analysis of FAIR models' properties have been studied extensively. We compare FAIR models to 7 other related and state-of-the-art models and demonstrate that FAIR is able to achieve a better trade-off between accuracy and unfairness. To the best of our knowledge, this is the first model that merges reweighting and adversarial approaches by means of a weighting function that can provide interpretable information about fairness of individual instances.
Declarative Approaches to Counterfactual Explanations for Classification
We propose answer-set programs that specify and compute counterfactual interventions as a basis for causality-based explanations to the outcomes from classification models. They can be applied with black-box models, and also with models that can be specified as logic programs, such as rule-based classifiers. The main focus is on the specification and computation of maximum-responsibility counterfactual explanations, with responsibility becoming an explanation score for features of entities under classification. We also extend the programs to bring into the picture semantic or domain knowledge. We show how the approach could be extended by means of probabilistic methods, and how the underlying probability distributions could be modified through the use of constraints.
Machine learning and Artificial Intelligence to revolutionize the world of art and creativity
Artificial intelligence is revolutionizing various industries, markets, and services. However, the creative industries and the art world have not yet been able to use the full potential of this technology. However, two Chilean entrepreneurs devised a platform to go further. Using the latest technology, they allow creators, amateur filmmakers, visual artists, even the film and music industry to use artificial intelligence algorithms in their work. This is Runway, a platform that integrates machine learning and artificial intelligence to the world of art and creativity.
Inside the world's first AI-powered satellite -- and its fight against clouds
On September 2 in French Guiana, an AI satellite was launched into the Earth's orbit for the first time in history. PhiSat-1 is now soaring at over 17,000 mph about 329 miles above us, monitoring polar ice and soil moisture through a hyperspectral-thermal camera, while also testing inter-satellite communication systems. Onboard the small satellite is an AI system developed by Ubotica and powered by Intel's Myriad 2 VPU -- the same chip inside many smart cameras, Magic Leap's AR goggles, and a $99 selfie drone. Its first task is filtering out images of clouds that impede the analysis. Clouds cover around two-thirds of Earth's surface at any given moment, which can severely disrupt the system's analysis.

Qualitative Investigation in Explainable Artificial Intelligence: A Bit More Insight from Social Science
Johs, Adam J., Agosto, Denise E., Weber, Rosina O.
This paper presents a focused analysis of human studies in explainable artificial intelligence (XAI) entailing qualitative investigation. We draw on the social science corpora of qualitative research to illustrate opportunities for making the human studies where XAI researchers used observations, interviews, focus groups, and/or questionnaires to capture qualitative data more rigorous. We contextualize the presentation of the XAI contributions included in our analysis according to the components of rigor described in the qualitative research literature: 1) underlying theories or frameworks, 2) methodological approaches, 3) data collection methods, and 4) data analysis processes. The results of our analysis support calls from others in the XAI community advocating for collaboration with experts from social disciplines to bolster rigor and effectiveness in human studies.
Image analysis for Alzheimer's disease prediction: Embracing pathological hallmarks for model architecture design
Brüningk, Sarah C., Hensel, Felix, Jutzeler, Catherine R., Rieck, Bastian
Alzheimer's disease (AD) is associated with local (e.g. brain tissue atrophy) and global brain changes (loss of cerebral connectivity), which can be detected by high-resolution structural magnetic resonance imaging. Conventionally, these changes and their relation to AD are investigated independently. Here, we introduce a novel, highly-scalable approach that simultaneously captures $\textit{local}$ and $\textit{global}$ changes in the diseased brain. It is based on a neural network architecture that combines patch-based, high-resolution 3D-CNNs with global topological features, evaluating multi-scale brain tissue connectivity. Our local-global approach reached competitive results with an average precision score of $0.95\pm0.03$ for the classification of cognitively normal subjects and AD patients (prevalence $\approx 55\%$).
