Multi-modal dialog for browsing large visual catalogs using exploration-exploitation paradigm in a joint embedding space [article]

Indrani Bhattacharya, Arkabandhu Chowdhury, Vikas Raykar
2019 arXiv   pre-print
Our system remembers the context of the dialog and uses an exploration-exploitation paradigm to assist in visual browsing.  ...  We formulate our problem of "showing k best images to a user" based on the dialog context so far, as sampling from a Gaussian Mixture Model in a high dimensional joint multi-modal embedding space, that  ...  However, this architecture cannot learn disentangled representations of the different attributes associated with a product.  ...

ANRL: Attributed Network Representation Learning via Deep Neural Networks

Zhen Zhang, Hongxia Yang, Jiajun Bu, Sheng Zhou, Pinggang Yu, Jianwei Zhang, Martin Ester, Can Wang
2018 Proceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence  
Network representation learning (RL) aims to transform the nodes in a network into low-dimensional vector spaces while preserving the inherent properties of the network.  ...  To capture the network structure, attribute-aware skip-gram model is designed based on the attribute encoder to formulate the correlations between each node and its direct or indirect neighbors.  ...  nodes with similar context should be similar in latent semantic space.  ...

Interactions in Visualization

Maria Lujan Ganuza
2018 Journal of Computer Science and Technology  
The main contributions of this thesis are: • A specification of a classification for data, attributes and data sets in the visualization context.  ...  In this context, it is necessary to define a representation for the data sets involved in the process.  ...  In Spinel Explorer, the designed interactions greatly improve the process of classifying mineral samples.  ...

Exemplars-guided Empathetic Response Generation Controlled by the Elements of Human Communication [article]

Navonil Majumder, Deepanway Ghosal, Devamanyu Hazarika, Alexander Gelbukh, Rada Mihalcea, Soujanya Poria
2021 arXiv   pre-print
The majority of existing methods for empathetic response generation rely on the emotion of the context to generate empathetic responses.  ...  However, empathy is much more than generating responses with an appropriate emotion.  ...  The EmpathyMentalHealth contains (context, response) pairs with annotated emotional presence, interpretation, exploration labels.  ...

ContextNet: representation and exploration for painting classification and retrieval in context

Noa Garcia, Benjamin Renoust, Yuta Nakashima
2019 International Journal of Multimedia Information Retrieval  
In this way, we are able to (1) capture information about the content and the style with the visual representations and (2) encode relationships between different artistic attributes with the ContextNet  ...  As context can be obtained from multiple sources, we explore two modalities of ContextNets: one based on multitask learning and another one based on knowledge graphs.  ...  Open Access This article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long  ...

An Adversarial Learning Framework For A Persona-Based Multi-Turn Dialogue Model [article]

Oluwatobi Olabiyi, Anish Khazane, Alan Salimov, Erik T. Mueller
2019 arXiv   pre-print
We also explore the trade-offs from using either variant of phredGAN on datasets with many but weak attribute modalities (such as with Big Bang Theory and Friends) and ones with few but strong attribute  ...  We also explore two approaches to accomplish the conditional discriminator: (1) phredGAN_a, a system that passes the attribute representation as an additional input into a traditional adversarial discriminator  ...  Encoder: The context RNN, cRN N takes the source attribute c i as an additional input by concatenating its representation with the output of eRN N as in Figure 1 .  ...
