Latent Space Translation via Semantic Alignment

1 code implementation NeurIPS 2023 Valentino Maiorca, Luca Moschella, Antonio Norelli, Marco Fumero, Francesco Locatello, Emanuele Rodolà

While different neural models often exhibit latent spaces that are alike when exposed to semantically related data, this intrinsic similarity is not always immediately discernible.

From Bricks to Bridges: Product of Invariances to Enhance Latent Space Communication

no code implementations2 Oct 2023 Irene Cannistraci, Luca Moschella, Marco Fumero, Valentino Maiorca, Emanuele Rodolà

It has been observed that representations learned by distinct neural networks conceal structural similarities when the models are trained under similar inductive biases.

Accelerating Transformer Inference for Translation via Parallel Decoding

3 code implementations17 May 2023 Andrea Santilli, Silvio Severino, Emilian Postolache, Valentino Maiorca, Michele Mancusi, Riccardo Marin, Emanuele Rodolà

We propose to reframe the standard greedy autoregressive decoding of MT with a parallel formulation leveraging Jacobi and Gauss-Seidel fixed-point iteration methods for fast inference.

Attention-likelihood relationship in transformers

1 code implementation15 Mar 2023 Valeria Ruscio, Valentino Maiorca, Fabrizio Silvestri

We analyze how large language models (LLMs) represent out-of-context words, investigating their reliance on the given context to capture their semantics.

Bootstrapping Parallel Anchors for Relative Representations

1 code implementation1 Mar 2023 Irene Cannistraci, Luca Moschella, Valentino Maiorca, Marco Fumero, Antonio Norelli, Emanuele Rodolà

The use of relative representations for latent embeddings has shown potential in enabling latent space communication and zero-shot model stitching across a wide range of applications.

Relative representations enable zero-shot latent space communication

no code implementations30 Sep 2022 Luca Moschella, Valentino Maiorca, Marco Fumero, Antonio Norelli, Francesco Locatello, Emanuele Rodolà

Neural networks embed the geometric structure of a data manifold lying in a high-dimensional space into latent representations.

Sparse Vicious Attacks on Graph Neural Networks

1 code implementation20 Sep 2022 Giovanni Trappolini, Valentino Maiorca, Silvio Severino, Emanuele Rodolà, Fabrizio Silvestri, Gabriele Tolomei

In this work, we focus on a specific, white-box attack to GNN-based link prediction models, where a malicious node aims to appear in the list of recommended nodes for a given target victim.

Metric Based Few-Shot Graph Classification

1 code implementation8 Jun 2022 Donato Crisostomi, Simone Antonelli, Valentino Maiorca, Luca Moschella, Riccardo Marin, Emanuele Rodolà

In this work, we tackle the problem of few-shot graph classification, showing that equipping a simple distance metric learning baseline with a state-of-the-art graph embedder allows to obtain competitive results on the task. While the simplicity of the architecture is enough to outperform more complex ones, it also allows straightforward additions.
