Machine Decisions and Human Consequences

no code implementations16 Nov 2018 Teresa Scantamburlo, Andrew Charlesworth, Nello Cristianini

As we increasingly delegate decision-making to algorithms, whether directly or indirectly, important questions emerge in circumstances where those decisions have direct consequences for individual rights and personal opportunities, as well as for the collective good.

Biased Embeddings from Wild Data: Measuring, Understanding and Removing

no code implementations16 Jun 2018 Adam Sutton, Thomas Lansdall-Welfare, Nello Cristianini

Many modern Artificial Intelligence (AI) systems make use of data embeddings, particularly in the domain of Natural Language Processing (NLP).

Right for the Right Reason: Training Agnostic Networks

no code implementations16 Jun 2018 Sen Jia, Thomas Lansdall-Welfare, Nello Cristianini

We consider the problem of a neural network being requested to classify images (or other inputs) without making implicit use of a "protected concept", that is a concept that should not play any role in the decision of the network.

History Playground: A Tool for Discovering Temporal Trends in Massive Textual Corpora

no code implementations4 Jun 2018 Thomas Lansdall-Welfare, Nello Cristianini

Recent studies have shown that macroscopic patterns of continuity and change over the course of centuries can be detected through the analysis of time series extracted from massive textual corpora.

Efficient Classification of Multi-Labelled Text Streams by Clashing

no code implementations12 Apr 2016 Ricardo Ñanculef, Ilias Flaounas, Nello Cristianini

Our method is composed of an online procedure used to efficiently map text into a low-dimensional feature space and a partition of this space into a set of regions for which the system extracts and keeps statistics used to predict multi-label text annotations.

The Anatomy of a Modular System for Media Content Analysis

no code implementations25 Feb 2014 Ilias Flaounas, Thomas Lansdall-Welfare, Panagiota Antonakaki, Nello Cristianini

As part of our ongoing effort in automating media content analysis for the social sciences, we have built a modular system by combining multiple AI modules into a flexible framework in which they can cooperate in complex tasks.
