In the past week, I worked on modifying my diagram and finished generating results. I also tried to draw meaningful insights from the validation results. After chatting with Xunfei, I finalized my poster and thought about elements to add to … Read More

In the past week, I finished the coding part of my project and did some validation work. I revised my diagram and worked on my paper and poster. Next week, I will be focusing more on my paper and poster.

I’ve mostly been working on making the poster and validating results. I found out that my original plan for validation would not work as nicely, so I will discuss with Xunfei to figure out what I can do. My diagram … Read More

I couldn’t do much due to comps, but collected all information from participants to conduct the validation process. I also ran their results on my software and recorded the results. This week, I will work on extracting relevant reviews from … Read More

In the past week, I mainly worked on implementing a simple interface for my program. I decided to take text inputs for skin type and beauty effects and use a button that returns the recommended products when clicked. To test … Read More

In the past week, I worked to finish implementing non content-based filtering which recommends products based on the user’s skin type and desired beauty effects. I was able to apply the concept of TF-IDF to judge which ingredients are heavily … Read More

In the past week, I worked on creating a survey to take inputs for content-based filtering, modified the skin type test questions, and obtained some responses. I also worked on implementing non-content-based filtering using TF-IDF which I am struggling with. … Read More

My project aims to create a skincare product recommender system based on the user’s skin type and ingredient composition of a product. The main component of the project is content-based filtering and the secondary component is non content-based filtering. For … Read More

In the past week, I found and fixed a bug for cosine similarity calculation in the code I was referencing. I was able to obtain more accurate recommendations across different product types. I also thought about and planned for next … Read More

In the past week, I worked on generating five recommendations from each of the the six product categories. I still have a confusion about the cosine similarity formula so I’m planning to meet with other faculties in the following week … Read More

In the past week, I worked on calculating the cosine similarity between the ingredient composition of an inputted item and that of the rest of the items in the data. I am struggling to decide on which formula to use … Read More

I made a visualization (plot) displaying ingredient composition similarity between different products and skin types. I attached two drop-down options for users to select from product categories and skin types. I also attached labels to the graph so that it … Read More

In the past week, I loaded the data, extracted ingredients from products, and made a document-term matrix containing product names and ingredient composition. I plan to visualize ingredient similarity between products this week. I haven’t faced many obstacles yet, but … Read More

I just worked on my final paper this week. I met with Xunfei to ask questions about it.

This week, I worked on the similar project posted online. While working on it, I found some challenges in modifying the content-based data set to fit the collaborative-filtering method. I might end up modifying my project from a hybrid recommender … Read More

This past week, I worked on mainly reading my new papers. I did a third pass reading on all my old papers and did at least second pass reading on the new ones. I tried finishing more than half of … Read More

This week, I revised my diagram again and selected papers to use for my proposal. I read through all of them carefully and wrote an outline for my proposal. I discussed the details of my ideas with Xunfei, modified some, … Read More

After meeting with Xunfei, I decided to modify my diagram a bit so I redesigned it from my practice proposal. I also collected more papers that could be used in my proposal and read more articles and research papers. I … Read More

This week, I changed my method from hybrid to content-based filtering because there isn’t much research done in the hybrid method. So I chose to improve the content-based filtering instead. I also wrote my proposal outline and revised my diagram … Read More

This week, I mainly worked on reviewing my papers carefully and summarizing them for the literature review. I also met and talked with Xunfei about my proposal idea and came up with a preliminary idea. I will have to work … Read More

In the past week, I searched and skimmed lots of papers to use for my own research. I also talked with Dave and Xunfei to refine my ideas. I also found a data scraping software to extract product information from … Read More

In the past week, I explored different ideas, talked to the faculty, and found more papers to read. I found lots of interesting paper related to my personalized skin care product recommendation idea. I found out that using content-based filtering … Read More

This week, I did a first pass reading for a total of 6 papers and visited the writing center for the annotated bibliography. Some of them turned out to be less relevant to the topic than they had appeared, but … Read More

I further developed my ideas and added more details to each of them. Then I talked to Xunfei about modifications and got more suggestions from her. We looked through the research paper I found on Google Scholars together and searched … Read More

1. My first idea stays the same, but Xunfei recommended me to enable rating and commenting under each product to make the app a bit more interactive & informative. I will order recommendations for different skin types by star ratings. … Read More

Name of Your Project Skip&Skin What research topic/question your project is going to address? One product can’t fit all. From beauty to skin care, people are thrown a bunch of products that are said to be popular or effective in … Read More
