Chatbot for fitness management using IBM Watson
Lola, Sai Rugved, Dhadvai, Rahul, Wang, Wei, Zhu, Ting
Chatbots have revolutionized the way humans interact with computer systems and they have substituted the use of service agents, call-center representatives etc. Fitness industry has always been a growing industry although it has not adapted to the latest technologies like AI, ML and cloud computing. In this paper, we propose an idea to develop a chatbot for fitness management using IBM Watson and integrate it with a web application. We proposed using Natural Language Processing (NLP) and Natural Language Understanding (NLU) along with frameworks of IBM Cloud Watson provided for the Chatbot Assistant. This software uses a serverless architecture to combine the services of a professional by offering diet plans, home exercises, interactive counseling sessions, fitness recommendations.
Counterfactual Memorization in Neural Language Models
Zhang, Chiyuan, Ippolito, Daphne, Lee, Katherine, Jagielski, Matthew, Tramรจr, Florian, Carlini, Nicholas
Modern neural language models widely used in tasks across NLP risk memorizing sensitive information from their training data. As models continue to scale up in parameters, training data, and compute, understanding memorization in language models is both important from a learning-theoretical point of view, and is practically crucial in real world applications. An open question in previous studies of memorization in language models is how to filter out "common" memorization. In fact, most memorization criteria strongly correlate with the number of occurrences in the training set, capturing "common" memorization such as familiar phrases, public knowledge or templated texts. In this paper, we provide a principled perspective inspired by a taxonomy of human memory in Psychology. From this perspective, we formulate a notion of counterfactual memorization, which characterizes how a model's predictions change if a particular document is omitted during training. We identify and study counterfactually-memorized training examples in standard text datasets. We further estimate the influence of each training example on the validation set and on generated texts, and show that this can provide direct evidence of the source of memorization at test time.
Explanation Container in Case-Based Biomedical Question-Answering
Goel, Prateek, Johs, Adam J., Shrestha, Manil, Weber, Rosina O.
The National Center for Advancing Translational Sciences(NCATS) Biomedical Data Translator (Translator) aims to attenuate problems faced by translational scientists. Translator is a multi-agent architecture consisting of six autonomous relay agents (ARAs) and eight knowledge providers (KPs). In this paper, we present the design of the Explanatory Agent (xARA), a case-based ARA that answers biomedical queries by accessing multiple KPs, ranking results, and explaining the ranking of results. The Explanatory Agent is designed with five knowledge containers that include the four original knowledge containers and one additional container for explanation - the Explanation Container. The Explanation Container is case-based and designed with its own knowledge containers.
Integrate IBM Watson with Whatsapp
IBM Watson Assistant is a chatbot that employs artificial intelligence. It comprehends customers queries and responds quickly, consistently, and accurately across any application, device, or channel. And mainly Watson Assistant is a service that allows you to integrate conversational interfaces into any website or app. In this tutorial, I will show how to use Kommunicate to link a Watson Assistant chatbot to WhatsApp, extending its capabilities. Assuming you're familiar with Watson Assistant and how it works.
IBM Watson Health Introduces New Opportunities for Imaging AI Adoption
Orchestration--of AI and of workflow--offers a new way to help imaging organizations improve radiologists' reading experience while significantly reducing the impact on IT IBM (NYSE: IBM) Watson Health is introducing a new AI orchestration offering to help imaging organizations experience the benefits of having AI applications work seamlessly together. IBM Watson Health will officially launch IBM Imaging AI Orchestrator at the Radiological Society of North America (RSNA) 2021 Annual Meeting in Chicago this week. In addition, IBM is announcing IBM Imaging Workflow Orchestrator with Watson, a new solution that modernizes the radiologist's reading experience while reducing the demands on IT and imaging system administrators. "We recognize that when it comes to applying AI in imaging, it's hard to go it alone," said David Gruen, MD, MBA, FACR, Chief Medical Officer, Imaging, Watson Health. "Because each AI application is developed in a unique way with a specific purpose, it can be challenging for organizations to review and assess each one, and then to deploy them in a way that's beneficial to radiologists and their patients. That's why, with the rapid proliferation of approved algorithms, staffing shortages, and complexity of disease, the IBM Imaging AI Orchestrator could not come at a better time."
Natural Language Processing in-and-for Design Research
Siddharth, L, Blessing, Lucienne T. M., Luo, Jianxi
We review the scholarly contributions that utilise Natural Language Processing (NLP) methods to support the design process. Using a heuristic approach, we collected 223 articles published in 32 journals and within the period 1991-present. We present state-of-the-art NLP in-and-for design research by reviewing these articles according to the type of natural language text sources: internal reports, design concepts, discourse transcripts, technical publications, consumer opinions, and others. Upon summarizing and identifying the gaps in these contributions, we utilise an existing design innovation framework to identify the applications that are currently being supported by NLP. We then propose a few methodological and theoretical directions for future NLP in-and-for design research.
