Today, I gave my first in-person presentation since the pandemic. It was awesome! I was talking about the study I performed with Nabeel Sulieman about data visualization in environments that use right-to-left writing systems.

In technical communication, the main thing is to keep the main thing the main thing. There are multiple ways to ensure this principle. Some of these ways require careful chart fine-tuning. However, there is one tool that is easy to master, fast to apply, and that provides a high return on the investment rate. I refer to chart titles. In this talk, I had two main theses. My first thesis is that most of you suck in communication (and not only data visualization).

Before becoming a freelancer data scientist, I used to work in a distributed company. Remote communication, including remote presentations were the norm for me, long before the remote work experiment no one asked for. In this post, I share some tips for delivering better presentations remotely.

A lot of texts that talk about presentation design cite a very clear rule: each slide has to contain only one idea. Here’s a slide from a presentation deck that says just that.

I have published the slide deck from my talk at the NDR conference in Iași, Romania.

In this post, I will try to convince you that speaking at a conference is an essential tool for professional development.

If you ever gave or attended a presentation, you are familiar with this situation: the presenter asks whether there are any questions and … nobody asks anything. This is an awkward situation. Why aren’t there any questions? Is it because everything is clear? Not likely. Everything is never clear. Is it because nobody cares? Well, maybe. There are certainly many people that don’t care. It’s a fact of life. Study your audience, work hard to make the presentation relevant and exciting but still, some people won’t care. Deal with it.

Today, during the EuroSciPy conference, I gave a presentation titled “Three most common mistakes in data visualization and how to avoid them”. The title of this presentation is identical to the title of the presentation that I gave in Barcelona earlier this year. The original presentation was approximately one and a half hours long. I knew that EuroSciPy presentations were expected to be shorter, so I was prepared to shorten my talk to half an hour. At some point, a couple of days before departing to Trento, I realized that I was only allocated 15 minutes. Fifteen minutes! Instead of ninety.

Today, I hosted a data visualization workshop, as a part of the workshop day adjacent to the fourth Israeli Data Science Summit. I really enjoyed this workshop, especially the follow-up questions. These questions are the reason I volunteer talking about data visualization every time I can. It may sound strange, but I learn a lot from the questions people ask me.

Yesterday, I talked in front of the Barcelona Data Science and Machine Learning Meetup about the most common mistakes in data visualization. I enjoyed talking with the local community very much. Judging by the feedback I received during and after the talk, they too, enjoyed my presentation. I uploaded my slides to Slideshare.

On Thursday, March 20, I will give a talk titled “Three most common mistakes in data visualization and how to avoid them.” I will be a guest of the Barcelona Data Science and Machine Learning Meetup Group. Right now, less than twenty-four hours after the lecture announcement, there are already seventeen people on the waiting list. I feel a lot of responsibility and am very excited.

Today, I made a presentation to the faculty of the Chisinau
Institute of Mathematics and Computer Science. The audience gathered in a conference room in Chisinau, and I was in my home office in Israel.

I consider teaching and presenting an integral part of my job as a data scientist. One way to become better at teaching is to collect feedback from the learners. I tried different ways of collecting feedback: passing a questionnaire, Polldaddy surveys or Google forms, or simply asking (no, begging) the learners to send me an e-mail with the feedback. Nothing really worked. The response rate was pretty low. Moreover, most of the feedback was a useless set of responses such as “it was OK”, “thank you for your time”, “really enjoyed”. You can’t translate this kind of feedback to any action.
