Bi-Weekly Report #2

Team roles for this report (write down name):

Facilitator(s): Jason Kennedy

Recorder(s): Simeon Kolev

Deliverer(s): Suryadyuti Baral

Planner(s): Kenza Slaoui, Tanay Bali

See last page for description of roles. Obviously one person can take more than one role or there can be more than one person per role or make your own roles!

0.    Describe briefly what the main goal of your team is (so the peer reviewer has some context). E.g. we are working on image classification for blah de blah. Our goal is blah de blah etc. In the initial part of the semester before your proposal it is ok to put down “we are still coming up with ideas on team project”.

Our team is working on classifying MRI images of 7023 brain scans from a combination of three different datasets. Our goal is to make a model capable of not only identifying the presence of a tumor, but identifying its type as well.

I.               What was done during the report period regarding the project: If you want to include code include this in the Appendix. Describe what the group did (including contributions of individual team members) with regards to the group project during this report period. Give enough details so I understand what you folks have been doing over the week. Include dates of your meeting(s) and who met on these days.

On 3/8, our group convened to begin EDA and discuss plans for our project proposal. We preprocessed the images, plotted the pixel intensity distribution, performed PCA, and plotted the first few components. After doing so, we decided that our goal should be not only to classify if an image has a tumor or not, but to classify its type as well. Suryadyuti did most of the coding, Jason wrote the bi-weekly report and planned meeting times, Simeon wrote the project proposal and helped with coding, and Kenza and Tanay directed our possible next steps and planned specific short and long term goals.

II.             What were obstacles faced if any in working on the project? This could be technical (like not being able to implement or understand particular techniques) or time issues (midterms for other courses etc).

Our group faced availability obstacles because there are five people in our group, so we found it difficult to find a time for all of us to meet up. Additionally, our combined dataset is roughly 5000 by 30000, so we are facing challenges with knitting and making our model time-efficient.

III.            What is the plan for the next reporting period including what each team member is planning to work on. Describe goals and potential timelines (“ I plan to finish understanding x to see if it can be implemented for our project by Wednesday etc”. )

By the next bi-weekly report, our plan is to preprocess the images using Python instead, because they were fuzzy and off-centered in R. Additionally, we are planning to bring the images back into R and do PCA to better understand our data and explain findings from our EDA.
