Can a Tabula Recta provide security in the XXI century?

no code implementations5 Dec 2023 Francisco Ruiz

In the not so unlikely scenario of total compromise of computers accessible to a group of users, they might be tempted to resort to human-computable paper-and-pencil cryptographic methods aided by a classic Tabula Recta, which helps to perform addition and subtraction directly with letters.

Word2net: Deep Representations of Language

no code implementations ICLR 2018 Maja Rudolph, Francisco Ruiz, David Blei

Most embedding methods rely on a log-bilinear model to predict the occurrence of a word in a context of other words.

Context Selection for Embedding Models

1 code implementation NeurIPS 2017 Liping Liu, Francisco Ruiz, Susan Athey, David Blei

Embedding models consider the probability of a target observation (a word or an item) conditioned on the elements in the context (other words or items).

Structured Embedding Models for Grouped Data

1 code implementation NeurIPS 2017 Maja Rudolph, Francisco Ruiz, Susan Athey, David Blei

Here we develop structured exponential family embeddings (S-EFE), a method for discovering embeddings that vary across related groups of data.

Infinite Factorial Dynamical Model

1 code implementation NeurIPS 2015 Isabel Valera, Francisco Ruiz, Lennart Svensson, Fernando Perez-Cruz

We propose the infinite factorial dynamic model (iFDM), a general Bayesian nonparametric model for source separation.

Bayesian Nonparametric Modeling of Suicide Attempts

no code implementations NeurIPS 2012 Francisco Ruiz, Isabel Valera, Carlos Blanco, Fernando Pérez-Cruz

In the present paper, we are interested in seeking the hidden causes behind the suicide attempts, for which we propose to model the subjects using a nonparametric latent model based on the Indian Buffet Process (IBP).
