This evening, I led the session on Spark R modeling in the book club (advanced-track) of Orange County R Users Group (OCRUG). The session covered contents of chapter 4 (modeling) and chapter 5 (pipeline) of the book Mastering Spark with R. I first gave a 20 min presentation going through the sparklyr Machine Learning Library (or MLlib), the main commands in exploratory data analyses (EDA), feature engineering, supervised learning, unsupervised learning, pipeline model, and model deployment through API. Then I switched to a 1h long exercise session guiding people to build a supervised learning pipeline model step by step. All of my teaching slides and exercise materials can be found here.

Present at INP Recruitment Session

This morning, I presented my recent research on head direction signals in the human brain to prospective interdepartmental neuroscience program (INP) PhD students. It was a 5min short presentation with 3min Q&A. I received many interesting and diverse questions from prospective students and also learned about my colleagues’ cool research through their presentations. I hope many young and energetic ‘brains’ will join the UCI neuroscience community in the coming year!

Present at Sfn Global Connectome

Today, I presented my latest research on head direction signals in the human brain at the Sfn Global Connectome. At the conference, I discussed with neuroscientists who study head direction signals in rodents, macaques, and drosophila. The clues I gained from the fascinating discoveries in other species really helped me consolidate my theories on how travel direction system works in the human brain.

I’m glad to receive this year’s Trainee Professional Development Award (TPDA) from Society for Neuroscience (Sfn). With this award, I receive complimentary registration to attend the upcoming Sfn Global Connectome virtual event. More importantly, I will also receive access to professional development opportunities on Neuronline in the following year and get to network with other receipients who conduct cool neuroscience research!

Attend NeurIPS 2020

I was fortunate to attend this year’s virtual Conference on Neural Information Processing System (NeurIPS 2020) thanks to the registration support from the NeurIPS 3rd Robot Learning Workshop. Although this is not a conference I’m regularly involved in, attending this conference is quite an experience filled with serendipity. (Note: part of this post is published as an article “What a cognitive psychologist learned from robotics” on the Medium Platform)

Today, I talked about my research on studying travel direction using a motion adaptation paradigm at Neuromatch Conference 3.0 (nmc3). I am glad to share my research with the general neuroscience community and I appreciate the good suggestions from other neuroscientists on the next step of my research.

Won 2nd place in WaiDATATHON

Over the past weekend, I participated in a Datathon “WaiDATATHON For Sustainable Future” hosted by WaiACCELERATE & Women in AI (WAI). As a member of the Foodwizer team, I worked on the challenge “Recommending dishes based on personal nutrient needs”. This time, I implemented association rule mining on a recipe ingredients dataset. Through this analysis, I discovered the probability of the co-occurrence of ingredients in a recipe. And our global team (with Betty from Netherland and Kirthy from India) won the 2nd place of the Datathon!

Present at iNAV 2020

Today, I presented my talk “Travel Direction as a Fundamental Component of Human Navigation” at the data blitz session of the 2020 Interdisciplinary Navigation Symposium (iNAV). The study is to look at the role of travel direction in the internal representation system of human navigation using a traditional paradigm in vision neuroscience - motion adaptation. The data will be incorporated as part of the first chapter of my Ph.D. dissertation and a recording of the talk should be available on the iNAV website since next week.
