 ====== Volunteer Data Analysis ======
+====Volunteer Matching====
-**Meeting: Jan 17, 2022**
+  * [[volunteer_data:volunteer_matching| Project Page]]
-  * Presented results of experiments on Volunteer data and Movielens
-  * Discussed the metrics for measuring performance on the two datasets
-  * Showed graphs of two methods and their performance on the two datasets
-  * Key: the BOA method still outperforms LDA in both datasets.
+====Persistent community detection====
+  * [[volunteer_data:tda_review|TDA Literature Review]]
-  * **Comments and Future work**
+====Recommendation and social network analysis====
-  * To compute metrics as a whole and not aggregate them separately for each user.
-  * To apply BOA method on a recommendation paper and compare the results
-  * To compile a representative code and send to the professor
-  * To read literature on latest work in RS.
-**Meeting: Jan 24, 2022**
+  * [[volunteer_data:meetings| Meeting Notes]]
-  * Discussed the possible alternatives of embedding the data, social net embedding
-  * Refined the life document to include user history pertaining to time, location and participation history
-  * Discussed a few papers that have used GNN for prediction
-  * **Comments and Future work**
-  * To read the papers related to Social Recommendation eg, Song et al (2019)
-  * Understand the nature of embeddings they used for the input data
-  * Summarise findings of papers (using GNN) whose data is similar to ours
-**Meeting: Feb 18, 2022**
-  * Presented a Survey on GNN Social recommendation
-  * Presented Item-to-Item KNN method used by Amazon
-  * Discussed two papers on Social Recommendation and presented their findings
-  * Paper 1: GNN for Social Recommendation - Fan, Ma,  Li, He,Zhao,Tang, and Yin. 2019. (ACM, WWW)
-  * Paper 2: Session-based Social Recommendation via Dynamic Graph Attention Networks, Song, Wang and Xiao (2019) – (ACM, WSDM)
-  * **Comments and Future work**
-  * To begin working on experiments related to dynamic session-based recommendation
-  * To make a list of the features and embeddings that can be used from our data,
-  * Determine session and neighbours based on our data, eg location based or participation based.
