Conversational Agents: Theory and Applications
Wahde, Mattias, Virgolin, Marco
In this chapter, we provide a review of conversational agents (CAs), discussing chatbots, intended for casual conversation with a user, as well as task-oriented agents that generally engage in discussions intended to reach one or several specific goals, often (but not always) within a specific domain. We also consider the concept of embodied conversational agents, briefly reviewing aspects such as character animation and speech processing. The many different approaches for representing dialogue in CAs are discussed in some detail, along with methods for evaluating such agents, emphasizing the important topics of accountability and interpretability. A brief historical overview is given, followed by an extensive overview of various applications, especially in the fields of health and education. We end the chapter by discussing benefits and potential risks regarding the societal impact of current and future CA technology.
Jury Learning: Integrating Dissenting Voices into Machine Learning Models
Gordon, Mitchell L., Lam, Michelle S., Park, Joon Sung, Patel, Kayur, Hancock, Jeffrey T., Hashimoto, Tatsunori, Bernstein, Michael S.
Whose labels should a machine learning (ML) algorithm learn to emulate? For ML tasks ranging from online comment toxicity to misinformation detection to medical diagnosis, different groups in society may have irreconcilable disagreements about ground truth labels. Supervised ML today resolves these label disagreements implicitly using majority vote, which overrides minority groups' labels. We introduce jury learning, a supervised ML approach that resolves these disagreements explicitly through the metaphor of a jury: defining which people or groups, in what proportion, determine the classifier's prediction. For example, a jury learning model for online toxicity might centrally feature women and Black jurors, who are commonly targets of online harassment. To enable jury learning, we contribute a deep learning architecture that models every annotator in a dataset, samples from annotators' models to populate the jury, then runs inference to classify. Our architecture enables juries that dynamically adapt their composition, explore counterfactuals, and visualize dissent.
How Does Artificial Intelligence Influence the Entertainment Industry?
Artificial Intelligence is widely accepted and prized globally in the media and entertainment industry as it is currently sweeping its way in. Works such as creating, designing, and editing become a cumbersome task manually in this industry. It is significantly reduced by the efficient use of Data modelling and Machine Learning. It makes analysing, synching, and editing much easier and error-free using complex Algorithms. Right from providing astounding VFX, AI and Talent analytics in the movies and games to the ease of streaming on platforms like Netflix, everything is just a touch away.
What is Scientific AI?
While chatbots and self-driving cars are some of the most widely recognised applications for artificial intelligence (AI), machine-learning technologies have made a decisive mark in the scientific world. Read on to discover more about scientific AI and the implications it has on everything from genomics to drug development. Technological advances have allowed scientists and researchers to unlock extraordinary amounts of data. Though without enough processing power, this data is meaningless. This is where artificial intelligence steps up.
