Expressive Power of ReLU and Step Networks under Floating-Point Operations

no code implementations26 Jan 2024 Yeachan Park, Geonho Hwang, Wonyeol Lee, Sejun Park

In this work, we analyze the expressive power of neural networks under a more realistic setup: when we use floating-point numbers and operations.

Minimum Width for Deep, Narrow MLP: A Diffeomorphism Approach

no code implementations30 Aug 2023 Geonho Hwang

By employing the aforementioned framework and the Whitney embedding theorem, we provide an upper bound for the minimum width, given by $\operatorname{max}(2d_x+1, d_y) + \alpha(\sigma)$, where $0 \leq \alpha(\sigma) \leq 2$ represents a constant depending on the activation function.

Minimal Width for Universal Property of Deep RNN

no code implementations25 Nov 2022 Chang hoon Song, Geonho Hwang, Jun Ho Lee, Myungjoo Kang

In this study, we prove the universality of deep narrow RNNs and show that the upper bound of the minimum width for universality can be independent of the length of the data.

Universal Approximation Property of Fully Convolutional Neural Networks with Zero Padding

no code implementations18 Nov 2022 Geonho Hwang, Myungjoo Kang

Despite its widespread adoption, our understanding of its universal approximation properties has been limited due to its intricate nature.

Finding the global semantic representation in GAN through Frechet Mean

no code implementations11 Oct 2022 Jaewoong Choi, Geonho Hwang, Hyunsoo Cho, Myungjoo Kang

This semantic basis represents sample-independent meaningful perturbations that change the same semantic attribute of an image on the entire latent space.

Analyzing the Latent Space of GAN through Local Dimension Estimation

no code implementations26 May 2022 Jaewoong Choi, Geonho Hwang, Hyunsoo Cho, Myungjoo Kang

In this paper, we approach this problem through a geometric analysis of latent spaces as a manifold.

Do Not Escape From the Manifold: Discovering the Local Coordinates on the Latent Space of GANs

2 code implementations ICLR 2022 Jaewoong Choi, Junho Lee, Changyeon Yoon, Jung Ho Park, Geonho Hwang, Myungjoo Kang

The global warpage implies that the latent space is not well-aligned globally and therefore the global traversal directions are bound to show limited success on it.

Discond-VAE: Disentangling Continuous Factors from the Discrete

no code implementations17 Sep 2020 Jaewoong Choi, Geonho Hwang, Myungjoo Kang

To represent these generative factors of data, we introduce two sets of continuous latent variables, private variable and public variable.
