Disentangling Model Multiplicity in Deep Learning

no code implementations17 Jun 2022 Ari Heljakka, Martin Trapp, Juho Kannala, Arno Solin

This observed 'predictive' multiplicity (PM) also implies elusive differences in the internals of the models, their 'representational' multiplicity (RM).

Deep Automodulators

2 code implementations NeurIPS 2020 Ari Heljakka, Yuxin Hou, Juho Kannala, Arno Solin

These networks can faithfully reproduce individual real-world input images like regular autoencoders, but also generate a fused sample from an arbitrary combination of several such images, allowing instantaneous 'style-mixing' and other new applications.

Gaussian Process Priors for View-Aware Inference

1 code implementation6 Dec 2019 Yuxin Hou, Ari Heljakka, Arno Solin

While frame-independent predictions with deep neural networks have become the prominent solutions to many computer vision tasks, the potential benefits of utilizing correlations between frames have received less attention.

retaining the identity of a face), sharp generated/reconstructed samples in high resolutions, and a well-structured latent space that supports semantic manipulation of the inputs.

Pioneer Networks: Progressively Growing Generative Autoencoder

1 code implementation9 Jul 2018 Ari Heljakka, Arno Solin, Juho Kannala

Instead, we propose the Progressively Growing Generative Autoencoder (PIONEER) network which achieves high-quality reconstruction with $128{\times}128$ images without requiring a GAN discriminator.

Recursive Chaining of Reversible Image-to-image Translators For Face Aging

2 code implementations14 Feb 2018 Ari Heljakka, Arno Solin, Juho Kannala

By treating the age phases as a sequence of image domains, we construct a chain of transformers that map images from one age domain to the next.
