Staying One Step Ahead Of AI
Industrial robots begins to create artistic painting. If you spend time on social media, you may have seen the "I forced a bot to watch" gimmick. A user claims that they programmed a "bot" to process thousands of hours of a show, and then produce a script based off of what it "saw." The accompanying script features a presumably automated, hilariously bizarre and unnatural exchange between the characters. The imitation is not quite right, but it strangely doesn't feel that far off, either.
CNN for Computer Vision with Keras and TensorFlow in Python
You're looking for a complete Convolutional Neural Network (CNN) course that teaches you everything you need to create a Image Recognition model in Python, right? You've found the right Convolutional Neural Networks course! Identify the Image Recognition problems which can be solved using CNN Models. Create CNN models in Python using Keras and Tensorflow libraries and analyze their results. Have a clear understanding of Advanced Image Recognition models such as LeNet, GoogleNet, VGG16 etc.
Deployment of Machine Learning Models
Learn how to put your machine learning models into production. Deployment of machine learning models, or simply, putting models into production, means making your models available to your other business systems. By deploying models, other systems can send data to them and get their predictions, which are in turn populated back into the company systems. Through machine learning model deployment, you and your business can begin to take full advantage of the model you built. When we think about data science, we think about how to build machine learning models, we think about which algorithm will be more predictive, how to engineer our features and which variables to use to make the models more accurate.
ML.NET Model Builder November Updates
ML.NET is an open-source, cross-platform machine learning framework for .NET developers. It enables integrating machine learning into your .NET apps without requiring you to leave the .NET ecosystem or even have a background in ML or data science. ML.NET provides tooling (Model Builder UI in Visual Studio and the cross platform ML.NET CLI) that automatically trains custom machine learning models for you based on your scenario and data. This release of ML.NET Model Builder brings numerous bug fixes and enhancements as well as new features, including advanced data loading options and streaming training data from SQL. In this post, we'll cover the following items: Previously, Model Builder did not offer any data loading options, relying on AutoML to detect column purpose, header, and separator as well as decimal separator style.
Turing Test At 70: Still Relevant For AI (Artificial Intelligence)?
ENGLAND - 1958: English Electric developed several notable pioneering computers during the 1950s. The DEUCE took up a huge space compared to modern computers and worked from 1450 thermionic valves which grew hot, blow outs were frequent. However the DEUCE proved a popular innovation and some models were working in to the 1970s. Photograph by Walter Nurnberg who transformed industrial photography after WWII using film studio lighting techniques. When computers were still in the nascent stages, Alan Turing published his legendary paper, "Computing Machinery And Intelligence," in the Mind journal in 1950.
SeMantic AnsweR Type prediction task (SMART) at ISWC 2020 Semantic Web Challenge
Mihindukulasooriya, Nandana, Dubey, Mohnish, Gliozzo, Alfio, Lehmann, Jens, Ngomo, Axel-Cyrille Ngonga, Usbeck, Ricardo
Each year the International Semantic Web Conference accepts a set of Semantic Web Challenges to establish competitions that will advance the state of the art solutions in any given problem domain. The SeMantic AnsweR Type prediction task (SMART) was part of ISWC 2020 challenges. Question type and answer type prediction can play a key role in knowledge base question answering systems providing insights that are helpful to generate correct queries or rank the answer candidates. More concretely, given a question in natural language, the task of SMART challenge is, to predict the answer type using a target ontology (e.g., DBpedia or Wikidata).
Non-Stationary Latent Bandits
Hong, Joey, Kveton, Branislav, Zaheer, Manzil, Chow, Yinlam, Ahmed, Amr, Ghavamzadeh, Mohammad, Boutilier, Craig
Users of recommender systems often behave in a non-stationary fashion, due to their evolving preferences and tastes over time. In this work, we propose a practical approach for fast personalization to non-stationary users. The key idea is to frame this problem as a latent bandit, where the prototypical models of user behavior are learned offline and the latent state of the user is inferred online from its interactions with the models. We call this problem a non-stationary latent bandit. We propose Thompson sampling algorithms for regret minimization in non-stationary latent bandits, analyze them, and evaluate them on a real-world dataset. The main strength of our approach is that it can be combined with rich offline-learned models, which can be misspecified, and are subsequently fine-tuned online using posterior sampling. In this way, we naturally combine the strengths of offline and online learning.
Symbolic AI for XAI: Evaluating LFIT Inductive Programming for Fair and Explainable Automatic Recruitment
Ortega, Alfonso, Fierrez, Julian, Morales, Aythami, Wang, Zilong, Ribeiro, Tony
Machine learning methods are growing in relevance for biometrics and personal information processing in domains such as forensics, e-health, recruitment, and e-learning. In these domains, white-box (human-readable) explanations of systems built on machine learning methods can become crucial. Inductive Logic Programming (ILP) is a subfield of symbolic AI aimed to automatically learn declarative theories about the process of data. Learning from Interpretation Transition (LFIT) is an ILP technique that can learn a propositional logic theory equivalent to a given black-box system (under certain conditions). The present work takes a first step to a general methodology to incorporate accurate declarative explanations to classic machine learning by checking the viability of LFIT in a specific AI application scenario: fair recruitment based on an automatic tool generated with machine learning methods for ranking Curricula Vitae that incorporates soft biometric information (gender and ethnicity). We show the expressiveness of LFIT for this specific problem and propose a scheme that can be applicable to other domains.
Debiasing Evaluations That are Biased by Evaluations
Wang, Jingyan, Stelmakh, Ivan, Wei, Yuting, Shah, Nihar B.
It is common to aggregate information and evaluate items by collecting ratings on these items from people. In this work, we focus on the bias introduced by people's observable outcome or experience from the entity under evaluation, and we call it the "outcome-induced bias". Let describe this notion of bias with the help of two common applications - teaching evaluation and peer review. Many universities use student ratings for teaching evaluation. However, numerous studies have shown that student ratings are affected by the grading policy of the instructor [16, 26, 5]. For instance, as noted in [26, Chapter 4]: "...the effects of grades on teacher-course evaluations are both substantively and statistically important, and suggest that instructors can often double their odds of receiving high evaluations from students simply by awarding A's rather than B's or C's." As a consequence, the association between student ratings and teaching effectiveness can become negative [5], and student ratings serve as a poor predictor on the follow-on course achievement of the students [8, 6]: "...teachers who are associated with better subsequent performance receive worst evaluations from their students."
