Despite the successes of pretrained language models, there are still few high-quality, general-purpose QA systems that are freely available. In response, we present Macaw, a versatile, generative question-answering (QA) system that we are making available to the community. Macaw is built on UnifiedQA, itself built on T5, and exhibits strong performance, zero-shot, on a wide variety of topics, including outperforming GPT-3 by over 10% (absolute) on Challenge300, a suite of 300 challenge questions, despite being an order of magnitude smaller (11 billion vs. 175 billion parameters). In addition, Macaw allows different permutations ("angles") of its inputs and outputs to be used, for example Macaw can take a question and produce an answer; or take an answer and produce a question; or take an answer and question, and produce multiple-choice options. We describe the system, and illustrate a variety of question types where it produces surprisingly good answers, well outside the training setup. We also identify question classes where it still appears to struggle, offering insights into the limitations of pretrained language models. Macaw is freely available, and we hope that it proves useful to the community. Macaw is available at https://github.com/allenai/macaw

Recent development in data-driven decision science has seen great advances in individualized decision making. Given data with individual covariates, treatment assignments and outcomes, researchers can search for the optimal individualized treatment rule (ITR) that maximizes the expected outcome. Existing methods typically require initial estimation of some nuisance models. The double robustness property that can protect from misspecification of either the treatment-free effect or the propensity score has been widely advocated. However, when model misspecification exists, a doubly robust estimate can be consistent but may suffer from downgraded efficiency. Other than potential misspecified nuisance models, most existing methods do not account for the potential problem when the variance of outcome is heterogeneous among covariates and treatment. We observe that such heteroscedasticity can greatly affect the estimation efficiency of the optimal ITR. In this paper, we demonstrate that the consequences of misspecified treatment-free effect and heteroscedasticity can be unified as a covariate-treatment dependent variance of residuals. To improve efficiency of the estimated ITR, we propose an Efficient Learning (E-Learning) framework for finding an optimal ITR in the multi-armed treatment setting. We show that the proposed E-Learning is optimal among a regular class of semiparametric estimates that can allow treatment-free effect misspecification. In our simulation study, E-Learning demonstrates its effectiveness if one of or both misspecified treatment-free effect and heteroscedasticity exist. Our analysis of a Type 2 Diabetes Mellitus (T2DM) observational study also suggests the improved efficiency of E-Learning.

The Medium Story you are about to read is the first story of a (hopefully) large collection of Machine Learning content. This series will be based on the book written by Aurelien Geron named "Hands-On Machine Learning With Scikit-Learn, Keras and Tensorflow". This story series will be a combination of highlights from the book and extra information gathered from the web. Enough to say I guess. According to the Aurelien Geron, the machine learning is "The science (and art) of programming computers so they can learn from data." and according to the IEEE the machine learning is "The study of computer algorithms that improve automatically through experience."

Max-AI is an artificial intelligence enabled robot that identifies recyclables and other items for recovery. Through deep learning technology, Max employs both multi-layered neural networks and a vision system to see and identify objects similar to the way a person does. The technology is driving improvements in Material Recovery Facility (MRF) design, operational efficiency, recovery, system optimization, maintenance.

Scenario-based question answering (SQA) requires retrieving and reading paragraphs from a large corpus to answer a question which is contextualized by a long scenario description. Since a scenario contains both keyphrases for retrieval and much noise, retrieval for SQA is extremely difficult. Moreover, it can hardly be supervised due to the lack of relevance labels of paragraphs for SQA. To meet the challenge, in this paper we propose a joint retriever-reader model called JEEVES where the retriever is implicitly supervised only using QA labels via a novel word weighting mechanism. JEEVES significantly outperforms a variety of strong baselines on multiple-choice questions in three SQA datasets.

TechRepublic's Karen Roby spoke with Carlos Contreras, AI and digital readiness director for Intel, about addressing the artificial intelligence skills gap with the AI for Workforce Program. The following is an edited transcript of their conversation. Karen Roby: We talk a lot about the tech skills gap. It seems like AI and cybersecurity are the two we tend to talk about a lot, that we need more people ready to fill those roles. But at Intel, you guys are building on a program to help change this and bridge the gap.

According to the Associated Press, Davis believes that "complex questions surrounding Artificial Intelligence require a holistic analysis and response that can only come from a broad liberal arts perspective."
