PhD position in Conversational AI

The University of Stavanger invites applications for a fully funded PhD position.

Intelligent personal assistants and chatbots (such as Siri, Cortana, the Google Assistant, and Amazon Alexa) are being used increasingly more for different purposes, including information access and retrieval. These conversational agents differ from traditional search engines in several important ways. They enable more naturalistic human-like interactions, where search becomes a dialog between the user and the machine. Unlike in traditional search engines, where a user-issued query is answered with a search result page, conversational agents can respond in a variety of ways, for example, asking questions back to the user for clarification.

The successful candidate will work on the design, development, and evaluation of conversational search systems. In particular, the candidate is expected to employ and develop deep learning techniques for understanding natural language requests and generating appropriate responses.

The candidate is required to have a background in machine learning or information retrieval.

PhD position in Deep Learning

I have a fully funded PhD position in deep learning.

Deep neural networks, a.k.a. deep learning, have transformed the fields of computer vision, speech recognition and machine translation, and now rivals human-level performance in a range of tasks. While the idea of neural networks dates several decades back, their recent success is attributed to three key factors: (1) vast computational power, (2) algorithmic advances, and (3) the availability of massive amounts of training data.
There is no doubt that deep learning will continue to transform other fields as well, including that of information retrieval. One major challenge is that for most information retrieval tasks, training data is not available in huge quantities. This is unlike, for example, to object recognition, where there are large scale resources at one’s disposal to train neural networks with (tens of) millions of parameters (e.g., the ImageNet database contains over 14 million images).

Deep learning is inspired by how the brain works. Yet, humans can learn and generalize from a very small number of examples. (A child, for example, does not need to see thousands of instances of cats, in many different sizes and from numerous different angles, to be able to recognize a cat and tell it apart from a dog.) Can deep neural networks be enhanced with this capability, i.e., to be able to learn and generalize from sparsely labeled data? The aim of this project is to answer this question, specifically, in the application domain of information retrieval.

PhD vacancy

I am looking for a PhD student to work on understanding complex information needs.

Web search engines have become remarkably effective in providing appropriate answers to queries that are issued frequently. However, when it comes to complex information needs, often formulated as natural language questions, responses become much less satisfactory (e.g., “Which European universities have active Nobel laureates?”). The goal of this project is to investigate how to improve query understanding and answer retrieval for complex information needs, using massive volumes of unstructured data in combination with knowledge bases. Query understanding entails, among others, determining the type (format) of the answer (single fact, list, answer passage, list of documents, etc.) and identifying the series of processing steps (retrieval, filtering, sorting, aggregation, etc.) required to obtain that answer. If the question is not understood or ambiguous, the system should ask for clarification in an interactive way. This could be done in a conversational manner, similarly to how it is done in commercial personal digital assistants, such as SIRI, Cortana, or Google Now.

The successful applicant would join a team of 2 other PhD students working on the FAETE project.
