D2DF2WOD: Learning Object Proposals for Weakly-Supervised Object Detection via Progressive Domain Adaptation

no code implementations2 Dec 2022 Yuting Wang, Ricardo Guerrero, Vladimir Pavlovic

In its warm-up domain adaptation stage, the model learns a fully-supervised object detector (FSOD) to improve the precision of the object proposals in the target domain, and at the same time learns target-domain-specific and detection-aware proposal features.

FS-DETR: Few-Shot DEtection TRansformer with prompting and without re-training

no code implementations ICCV 2023 Adrian Bulat, Ricardo Guerrero, Brais Martinez, Georgios Tzimiropoulos

Importantly, we show that our system is not only more flexible than existing methods, but also, it makes a step towards satisfying desideratum (c).

SOS! Self-supervised Learning Over Sets Of Handled Objects In Egocentric Action Recognition

no code implementations10 Apr 2022 Victor Escorcia, Ricardo Guerrero, Xiatian Zhu, Brais Martinez

To overcome both limitations, we introduce Self-Supervised Learning Over Sets (SOS), an approach to pre-train a generic Objects In Contact (OIC) representation model from video object regions detected by an off-the-shelf hand-object contact detector.

Multi-attribute Pizza Generator: Cross-domain Attribute Control with Conditional StyleGAN

1 code implementation22 Oct 2021 Fangda Han, Guoyao Hao, Ricardo Guerrero, Vladimir Pavlovic

To synthesize a pizza image with view attributesoutside the range of natural training images, we design a CGI pizza dataset PizzaView using 3D pizza models and employ it to train a view attribute regressor to regularize the generation process, bridging the real and CGI training datasets.

CHEF: Cross-modal Hierarchical Embeddings for Food Domain Retrieval

1 code implementation4 Feb 2021 Hai X. Pham, Ricardo Guerrero, Jiatong Li, Vladimir Pavlovic

Despite the abundance of multi-modal data, such as image-text pairs, there has been little effort in understanding the individual entities and their different roles in the construction of these data instances.

MPG: A Multi-ingredient Pizza Image Generator with Conditional StyleGANs

1 code implementation4 Dec 2020 Fangda Han, Guoyao Hao, Ricardo Guerrero, Vladimir Pavlovic

Because of the complex nature of the multilabel image generation problem, we also regularize synthetic image by predicting the corresponding ingredients as well as encourage the discriminator to distinguish between matched image and mismatched image.

Cross-Modal Retrieval and Synthesis (X-MRS): Closing the Modality Gap in Shared Representation Learning

1 code implementation2 Dec 2020 Ricardo Guerrero, Hai Xuan Pham, Vladimir Pavlovic

A key to making CFA possible is multi-modal shared representation learning, which aims to create a joint representation of the multiple views (text and image) of the data.

Learning Disentangled Latent Factors from Paired Data in Cross-Modal Retrieval: An Implicit Identifiable VAE Approach

no code implementations1 Dec 2020 Minyoung Kim, Ricardo Guerrero, Vladimir Pavlovic

We deal with the problem of learning the underlying disentangled latent factors that are shared between the paired bi-modal data in cross-modal retrieval.

Deep Cooking: Predicting Relative Food Ingredient Amounts from Images

no code implementations26 Sep 2019 Jiatong Li, Ricardo Guerrero, Vladimir Pavlovic

In this paper, we study the novel problem of not only predicting ingredients from a food image, but also predicting the relative amounts of the detected ingredients.

The Art of Food: Meal Image Synthesis from Ingredients

1 code implementation9 May 2019 Fangda Han, Ricardo Guerrero, Vladimir Pavlovic

In this work we propose a new computational framework, based on generative deep models, for synthesis of photo-realistic food meal images from textual descriptions of its ingredients.

Meta-Weighted Gaussian Process Experts for Personalized Forecasting of AD Cognitive Changes

no code implementations19 Apr 2019 Ognjen Rudovic, Yuria Utsumi, Ricardo Guerrero, Kelly Peterson, Daniel Rueckert, Rosalind W. Picard

We introduce a novel personalized Gaussian Process Experts (pGPE) model for predicting per-subject ADAS-Cog13 cognitive scores -- a significant predictor of Alzheimer's Disease (AD) in the cognitive domain -- over the future 6, 12, 18, and 24 months.

Personalized Gaussian Processes for Forecasting of Alzheimer's Disease Assessment Scale-Cognition Sub-Scale (ADAS-Cog13)

1 code implementation22 Feb 2018 Yuria Utsumi, Ognjen Rudovic, Kelly Peterson, Ricardo Guerrero, Rosalind W. Picard

In this paper, we introduce the use of a personalized Gaussian Process model (pGP) to predict per-patient changes in ADAS-Cog13 -- a significant predictor of Alzheimer's Disease (AD) in the cognitive domain -- using data from each patient's previous visits, and testing on future (held-out) data.

Personalized Gaussian Processes for Future Prediction of Alzheimer's Disease Progression

1 code implementation1 Dec 2017 Kelly Peterson, Ognjen Rudovic, Ricardo Guerrero, Rosalind W. Picard

In this paper, we introduce the use of a personalized Gaussian Process model (pGP) to predict the key metrics of Alzheimer's Disease progression (MMSE, ADAS-Cog13, CDRSB and CS) based on each patient's previous visits.
