WebDec 20, 2024 · The BFR Algorithm for clustering is based on the definition of three different sets of data: (a) The retained set (RS) The set of data points which are not recognized to belong to any cluster, and need to be retained in the buffer; (b) The discard set (DS) The set of data points which can be discarded after updating the summary statistics; (c) WebJan 2, 2024 · I have to implement the BFR algorithm in C and one of the tasks is to handle memory: in the BFR algorithm we have to load a chunk of data (reading it from a file) that perfectly fits in main memory (I suppose RAM) and repeat the clustering process for each chunk. I'm here to ask which is the correct approach to this problem.
