An overview of NLP evaluation metrics and distance/similarity measures

May 15, 2021

Free Friday Talk, Ebot7 GmbH, Munich, Germany

Evaluation in NLP is an open problem especially when it comes to the evaluation of generated text. It’s a really hard problem and therefore there is no single go to evaluation metric available. What makes this problem even more hard is that metrics need to evaluate competing goals i.e Correctness (quality)/Specicity (diversity).

Multiprocessing vs Multithreading vs Async IO

Free Friday Talk, Ebot7 GmbH, Munich, Germany

In this free Friday talk we discussed about what are the differences between multiprocessing and multithreading in Python. We also talked about what is AsyncIO and how to implement it in Python.

Multi-Domain Dialogue State Tracking

March 18, 2020

Free Friday Talk, Ebot7 GmbH, Munich, Germany

Last summer our team of data scientists attended the 57th Annual Meeting of the Association for Computational Linguistics (ACL) at Florence. It was a great learning and team bonding experience for all of us. During the conference we learned about this really interesting paper - Transferable Multi-Domain State Generator for Task-Oriented Dialogue Systems. It received two awards in the conference, an outstanding paper award the best paper award at NLP for Conversational AI Workshop.

An Introduction to Automatic Speech Recognition

July 10, 2019

Meetup Talk, 4th Munich AI Meetup, SIXT Autovermietung München Pullach, Munich, Germany

The goal of this presentation was to give a short introduction about automatic speech recognition. We are mainly focused on the classical ASR pipeline and in that we discussed what audio signals are? We also discussed a common feature extraction technique that is used with audio data and we also talked about other components of the pipeline like Acoustic Model, Language Model and Hypothesis Search. Towards the end we discussed an evaluation metric that is used to compare the performance of various ASR models.
