# 14th July 2003 - Data visualisation

Tom Minka has offered to provide the following review:

## Data visualization: New methods and unsolved problems

Visualization is a powerful method for checking model assumptions and generally learning about data. However, the literature is very scattered, making it difficult to get a coherent picture of what has been done and what are the open problems. I will give a tour of methods for multivariate visualization, including some new methods, emphasizing the connections between them. In many cases, visualization is intertwined with inference, and requires optimization of a suitably chosen cost function, making it quite similar to problems in machine learning. I will also walk through examples of using visualization to learn about real datasets.
