This week, our group split into two groups: those that are working on the same dataset, and the other that is organizing a new dataset. I am in the first group and I finally decided that I would be investigating graph clustering with missing data. The other group is building a smaller dataset of fruits. There are two categories: strawberries, and wedge strawberries. Fifteen pictures from each category are included in the small dataset. Below is a picture of each.

In regards to my contribution, given a graph with partial observations, I still want to identify the underlying clusters. This leads me to the problem of clustering graphs with missing data. For the next few weeks, I will consider the problem of identifying clusters when the input is a partially observed adjacency matrix of an unweighted graph. Two convex algorithms will be my aim but are not completely promised. A video about this topic is below:

For the other group, I do not know the specifics but I understand where data can be seen for me which is on AirTable. I have used AirTable before and it formats data in a readable structure. The data can either be downloaded the data as a CSV file or requested as a JSON. The table has 150 records from 5 workers. In the future, I hope to help them out after I am satisfied with my part. A video explaining Airtable is below: 

In unrelated news, I recently found myself super intrigued by this relatively new material called "aerogel". It is a synthetically-produced gel with its liquid aspect replaced with gas. The result is a transparent, porous solid with an extremely low density and low thermal conductivity. The properties do not stop there as they can also absorb a lot due to their structure and waterproof items. I believe it will have a lot of potential in the near future. Nasa's spacesuits can cost up to $500 million dollars from scratch and much of the complexity/cost is derived from trying to disperse heat from the internals. With aerogel, suits might be at a lower cost, lower weight, and lower complexity. Below is am image on aerogel:

This week has been interesting, to say the least. Something I have achieved over the break was finishing my application for the BU Rise program. The summer research camp in Boston is very intriguing to me because I get to work with professors on their research. This activity is something I might want to pursue in the near future which is why I really want to attend the program. My application has five essays that took me quite the time to complete. I asked friends and teachers to look over my pieces. This caused my works to under several iterations but in the end, it was all worth it. Wish me luck! Above is a video describing what students do during BU RISE. I guess there's also the fact that I want to visit Boston during the summer. I came from Massachusetts to California after 8th grade. It's been 3+ years and you bet I'm missing my home. I think I even had a plan for when I get there. First I want to meet up with my friends at Lexington and afterward go see family

Crowd-source Image Labeling [Technical Journal]

       The question at hand is how to increase crowdsourcing image labeling efficiency which has been an apparent issue in Machine Learning. Steps taken have revolved around solving highly variable accuracy of the data. The paper " Crowdsourcing – A Step Towards Advanced Machine Learning " briefly talks on how has crowdsourcing is used in the real world. " On the Efficiency of Data Collection for Crowdsourced Classification " uses the most common data policies for crowdsourced classification on datasets and compares their accuracy to conclude each policy's lower and upper bounds as well as adaptive policies out-perform those that do not. " Distance Metric Learning: A Comprehensive Survey " lists out algorithms utilizing a distance metric and its summary, works, strengths, and weaknesses. " Semi-Crowdsourced Clustering: Generalizing Crowd Labeling by Robust Distance Metric Learning " touches upon the issue that data clustering has trouble find

First Month

The first four weeks of this Caltech Stem class have been interesting, to say the least. Much of the material we went into have been all over the place with various objectives. We started off with teamwork exercises, watching college students present their research, replicating one for ourselves, writing a concept map, and going to Caltech to meet Dr. Hassibi. We had two, teamwork workshops for the first two weeks. One of which was the dominoes problem where each student was given two dominoes and we were instructed to get three dominoes per person by exchanging dominoes for chips and chips for dominoes. Instructions were very vague other than that everyone must have a domino to "survive" a round. We struggled in the first few attempts but through several days of discussion and trial & error, we were able to find a way to accomplish our goal. Some key underlying goals of this exercise were the importance of leadership, communication, and open-mindedness
