• Title: From meaning to perception -- exploring the space between word and odor perception embeddings
• Authors: Janek Amann, Manex Agirrezabal
• Abstract summary: We propose the use of the Word2vec algorithm in order to obtain odor perception embeddings (or smell embeddings) The meaningfulness of these embeddings suggests that aesthetics might provide enough constraints for using algorithms motivated by distributional semantics. We have also employed the embeddings in an attempt to understand the aesthetic nature of perfumes, based on the difference between real and randomly generated perfumes.

• Abstract: In this paper we propose the use of the Word2vec algorithm in order to obtain odor perception embeddings (or smell embeddings), only using publicly available perfume descriptions. Besides showing meaningful similarity relationships among each other, these embeddings also demonstrate to possess some shared information with their respective word embeddings. The meaningfulness of these embeddings suggests that aesthetics might provide enough constraints for using algorithms motivated by distributional semantics on non-randomly combined data. Furthermore, they provide possibilities for new ways of classifying odors and analyzing perfumes. We have also employed the embeddings in an attempt to understand the aesthetic nature of perfumes, based on the difference between real and randomly generated perfumes. In an additional tentative experiment we explore the possibility of a mapping between the word embedding space and the odor perception embedding space by fitting a regressor on the shared vocabulary and then predict the odor perception embeddings of words without an a priori associated smell, such as night or sky.

• Conjuring Semantic Similarity [59.18714889874088]
  The semantic similarity between two textual expressions measures the distance between their latent'meaning' We propose a novel approach whereby the semantic similarity among textual expressions is based not on other expressions they can be rephrased as, but rather based on the imagery they evoke. Our method contributes a novel perspective on semantic similarity that not only aligns with human-annotated scores, but also opens up new avenues for the evaluation of text-conditioned generative models.

• Word sense extension [8.939269057094661]
  We present a paradigm of word sense extension (WSE) that enables words to spawn new senses toward novel context. We develop a framework that simulates novel word sense extension by partitioning a polysemous word type into two pseudo-tokens that mark its different senses. Our framework combines cognitive models of chaining with a learning scheme that transforms a language model embedding space to support various types of word sense extension.

  Word-level saliency explanations are often used to communicate feature-attribution in text-based models. Recent studies found that superficial factors such as word length can distort human interpretation of the communicated saliency scores. We investigate how the marking of a word's neighboring words affect the explainee's perception of the word's importance in the context of a saliency explanation.

The findings are relevant for research on concept acquisition and representation, as well as for applications that can benefit from a better understanding of perceptual spaces of sensory experiences.

  This paper introduces a new method for building open-ended vocabularies of primitive visual concepts represented in a GAN's latent space. Our approach is built from three components: automatic identification of perceptually salient directions based on their layer selectivity; human annotation of these directions with free-form, compositional natural language descriptions. Experiments show that concepts learned with our approach are reliable and composable -- generalizing across classes, contexts, and observers.

  We propose a new method that amends the label distribution of each facial image by leveraging correlations among expressions in the semantic space. By comparing semantic and task class-relation graphs of each image, the confidence of its label distribution is evaluated. Experimental results demonstrate the proposed method is more effective than compared state-of-the-art methods.
