Participating in Kaggle Days and other Kaggle meetups
A good way to build connections with other Kagglers (and also be more easily accepted into a team) is simply to meet them. Meetups and conferences have always been a good way to do so, even if they do not specifically deal with Kaggle competitions, because the speakers talk about their experiences on Kaggle or because the topics have been dealt with in Kaggle competitions. For instance, many Research competitions require successful competitors to write papers on their experience, and the paper could be presented or quoted during a conference speech.
There were no special events directly connected with Kaggle until 2018, when LogicAI, a company created by Maria Parysz and Paweł Jankiewicz, arranged the first Kaggle Days event in Warsaw, Poland, in collaboration with Kaggle. They gathered over 100 participants and 8 Kaggle Grandmasters as speakers.
More Kaggle Days events followed. Here are the events that were arranged...
