DSPT#66 – Going from Bio stats to sentences classification. (Aveiro)

28 November, 2019 @ 18:30 - 21:00


Join us on this meetup at Bosch were we bring new topics. Will be discussed topics about Bio statistics and informatics passing to a topic on Natural Language Processing.

The preliminary agenda for the meetup is the following:
• 18:30-19:00: Welcome and get together
• 19:00-19:30: Talk 1: “Bioinformatics – A journey from peas to AI” – David Silva
• 19:40-19:45: Group photo
• 19:45-20:15: Networking / Coffee Break
• 20:15-20:45: Talk 2: “Conversation Topic Classification at Talkdesk” – Pedro Verruma
• 20:50: Closing
• 21:00: Dinner is optional but it might be an excellent opportunity for networking ( https://doodle.com/poll/sd5wczdih5kcv6u4 )

This meetup is sponsored by Bosch (https://www.bosch.com/)
See you there!

Talk 1: Bioinformatics – A journey from peas to AI

Abstract: Bioinformatics is a rapid growing field with a great impact in society where the benefits can be seen in the great advances in medical diagnostics, production of medicine, increase of crop’s yield in agriculture, understanding of human history, biotech industry among many other applications that impact our daily lives. Due to the many technological advances in this field, there is an exponential increase in the data being generated and there is also a great need to process, understand and create value from all the data. In order to do so, we have to understand the pipeline that goes from biological sample to the final output. In this journey from peas to AI, bioinformatics will be deconstructed into its basic blocks and reconstructed in a way that will explain how the mindset of biologists has changed in the last decades and what value they bring to society.

Short Bio: David Silva is PhD candidate at CIBIO-InBIO, doing a PhD in the field of plant genomics and bioinformatics. David has background in pharmaceutical sciences where he understood that human health could be improved more efficiently by acting upstream, by better exploiting what nature as to offer. It was the complexity of plants that drove him to join the master in Functional Biology and Plant Biotechnology where he as able to understand how to exploit all the potential of plants as a vital resource for humanity. During his master he addressed grapevine genomics and bioinformatics where he performed an in-depth study of the genome of several populations of grapevine varieties.

Talk 2: Conversation Topic Classification at Talkdesk

Abstract: Talkdesk offers a Contact Center in the cloud that handles thousands of calls every day, and for each call we want to know what are the different intents expressed during the conversation (e.g. customer complaining, request for information, scheduling a meeting, etc). In this talk we will show how we are tackling this issue, starting by explaining how we do sentence classification to identify possible changes in the conversation topic, using intent detection techniques that take advantage of Neural Network approaches based on LSTMs. With sentence classification we can then group together sentences related to a specific topic (aka moments). We are also going to show how it is possible to group similar moments using unsupervised methods, such as clustering, and, on top of that, use supervised classification to identify moments that were manually annotated on previous conversations. To achieve this we are using state-of-the-art sentence2vec approaches like BERT, InferSent, Universal Sentence Encoder and others.

Short Bio: My name is Pedro Verruma and I’m an Engineering Manager at Talkdesk. I’ve worked in Artificial Intelligence for the past 10 years, most of them using Natural Language Processing techniques to create innovative products for companies like Wizdee, Critical Software and now Talkdesk. Among others, I’ve specialized in solutions for Knowledge Representation, Semantic Search, Recommendation and Text Classification. I’m also a container deployment and microservices enthusiast with focus on high-availability and high-scalability.
