Deep Perceptual Similarity is Adaptable to Ambiguous Contexts

1 code implementation5 Apr 2023 Gustav Grund Pihlgren, Fredrik Sandin, Marcus Liwicki

The concept of image similarity is ambiguous, and images can be similar in one context and not in another.

Identifying and Mitigating Flaws of Deep Perceptual Similarity Metrics

1 code implementation6 Jul 2022 Oskar Sjögren, Gustav Grund Pihlgren, Fredrik Sandin, Marcus Liwicki

This work investigates the most common DPS metric, where deep features are compared by spatial position, along with metrics comparing the averaged and sorted deep features.

Pretraining Image Encoders without Reconstruction via Feature Prediction Loss

1 code implementation16 Mar 2020 Gustav Grund Pihlgren, Fredrik Sandin, Marcus Liwicki

To evaluate this method we perform experiments on three standard publicly available datasets (LunarLander-v2, STL-10, and SVHN) and compare six different procedures for training image encoders (pixel-wise, perceptual similarity, and feature prediction losses; combined with two variations of image and feature encoding/decoding).

Improving Image Autoencoder Embeddings with Perceptual Loss

1 code implementation10 Jan 2020 Gustav Grund Pihlgren, Fredrik Sandin, Marcus Liwicki

Autoencoders are trained to embed images from three different computer vision datasets using perceptual loss based on a pretrained model as well as pixel-wise loss.

Subword Semantic Hashing for Intent Classification on Small Datasets

3 code implementations16 Oct 2018 Kumar Shridhar, Ayushman Dash, Amit Sahu, Gustav Grund Pihlgren, Pedro Alonso, Vinaychandran Pondenkandath, Gyorgy Kovacs, Foteini Simistira, Marcus Liwicki

In this paper, we introduce the use of Semantic Hashing as embedding for the task of Intent Classification and achieve state-of-the-art performance on three frequently used benchmarks.
