Language as the Medium: Multimodal Video Classification through text only

no code implementations19 Sep 2023 Laura Hanu, Anita L. Verő, James Thewlis

Despite an exciting new wave of multimodal machine learning models, current approaches still struggle to interpret the complex contextual relationships between the different modalities present in videos.

VTC: Improving Video-Text Retrieval with User Comments

1 code implementation19 Oct 2022 Laura Hanu, James Thewlis, Yuki M. Asano, Christian Rupprecht

In this paper, we a) introduce a new dataset of videos, titles and comments; b) present an attention-based mechanism that allows the model to learn from sometimes irrelevant data such as comments; c) show that by using comments, our method is able to learn better, more contextualised, representations for image, video and audio representations.

Unsupervised Learning of Landmarks by Descriptor Vector Exchange

1 code implementation ICCV 2019 James Thewlis, Samuel Albanie, Hakan Bilen, Andrea Vedaldi

Equivariance to random image transformations is an effective method to learn landmarks of object categories, such as the eyes and the nose in faces, without manual supervision.

The theory of deep learning is now considered largely solved, and is well understood by researchers and influencers alike.

Modelling and unsupervised learning of symmetric deformable object categories

no code implementations NeurIPS 2018 James Thewlis, Hakan Bilen, Andrea Vedaldi

We propose a new approach to model and learn, without manual supervision, the symmetries of natural objects, such as faces or flowers, given only images as input.

Substitute Teacher Networks: Learning with Almost No Supervision

1 code implementation1 Apr 2018 Samuel Albanie, James Thewlis, Joao F. Henriques

Learning through experience is time-consuming, inefficient and often bad for your cortisol levels.

Unsupervised learning of object frames by dense equivariant image labelling

no code implementations NeurIPS 2017 James Thewlis, Hakan Bilen, Andrea Vedaldi

One of the key challenges of visual perception is to extract abstract models of 3D objects and object categories from visual measurements, which are affected by complex nuisance factors such as viewpoint, occlusion, motion, and deformations.
