MAEDAY: MAE for few and zero shot AnomalY-Detection

1 code implementation25 Nov 2022 Eli Schwartz, Assaf Arbelle, Leonid Karlinsky, Sivan Harary, Florian Scheidegger, Sivan Doveh, Raja Giryes

We propose using Masked Auto-Encoder (MAE), a transformer model self-supervisedly trained on image inpainting, for anomaly detection (AD).

Constrained deep neural network architecture search for IoT devices accounting for hardware calibration

no code implementations NeurIPS 2019 Florian Scheidegger, Luca Benini, Costas Bekas, A. Cristiano I. Malossi

The narrow-space search of floating-point models improves the accuracy on CIFAR10 of an established IoT model from 70. 64% to 74. 87% within the same memory constraints.

Constrained deep neural network architecture search for IoT devices accounting hardware calibration

no code implementations24 Sep 2019 Florian Scheidegger, Luca Benini, Costas Bekas, Cristiano Malossi

We further improve the accuracy to 82. 07% by including 16-bit half types and we obtain the best accuracy of 83. 45% by extending the search with model optimized IEEE 754 reduced types.

PAGAN: Portfolio Analysis with Generative Adversarial Networks

no code implementations19 Sep 2019 Giovanni Mariani, Yada Zhu, Jianbo Li, Florian Scheidegger, Roxana Istrate, Costas Bekas, A. Cristiano I. Malossi

Sound financial theories demonstrate that in an efficient marketplace all information available today, including expectations on future events, are represented in today prices whereas future price trend is driven by the uncertainty.

BAGAN: Data Augmentation with Balancing GAN

4 code implementations26 Mar 2018 Giovanni Mariani, Florian Scheidegger, Roxana Istrate, Costas Bekas, Cristiano Malossi

The generator in the GAN is initialized with the encoder module of an autoencoder that enables us to learn an accurate class-conditioning in the latent space.
