Master Thesis: Efficient implementation of State-of-the-Art Word/Sentence Embeddings

Job Description

Date: Nov 22, 2019

Mobile Device Research

Technology leadership is essential for Ericsson’s success and the mobile device segment is one of the most aggressive technology drivers in the world with its extreme requirements on properties such as energy efficiency, cost, and size.

Ericsson Research is therefore exploring and developing cutting edge software and hardware solutions in the mobile device segment.

We use the collective term devices for equipment connecting, possibly indirectly, to our networks; e.g. smartphones, wearables, XR-glasses, implants, IoT sensors.


Ericsson Research

Ericsson Research (ER) is the central research organization within Ericsson. We are over 650 researchers in eight countries. Our mission is to provide Ericsson with system concepts, technology, and intellectual property, to secure long-term success and competitiveness of Ericsson.

World-class innovation is achieved through cooperation within Ericsson as well as with external partners, customers, universities, and research institutes.

The thesis work is expected to be carried out at, or in collaboration with the Device Platform Research unit, Ericsson Research, Lund, Sweden. The unit focuses on mobile device related research with the charter to create novel concepts and technologies, do proof-of-concept prototyping, be a strategic eco-system influencer, serve as a pool of expertise supporting strategy, business and standardization functions within Ericsson, and create strategically important intellectual property.


Thesis Description

A modern branch of natural language processing (NLP) algorithms is based on word embeddings generated using neural networks.  As the algorithms develop and become more complex, their implementations run slower and consume more energy.

This thesis work aims at finding ways to implement such algorithms more efficiently, for example by complexity reduction and co-design between algorithms and hardware.

The thesis will be concluded with a presentation for the Ericsson research team.



This thesis project aims at students in electrical engineering, computer science, computer engineering, mathematics or similar. The thesis project is only available to persons working towards a Master of Science degree.

Extent: 1 student

Location: Lund

Preferred Starting Date: January 2020
