Performance Test: Analyzing token frequencies

(22.Jul. 18:16)

For analyzing token frequencies, I have implemented two different designs.Design A: For different data sources, create specific data readers that convert your data into Records. For frequency analysis, operate on the abstraction of RecordAdvantage: Easy to maintain, implement once and for all Reduces complexity of the project Disadvantage: Poor performance High memory requirement, since you are doing analysis record by [...] [?]

Midterm update

(19.Jul. 16:24)

As many of you know, we are working on a patient matching module for OpenMRS that will allow users to identify records that belong to the same patient among different data sources.In the first part of SoC, I’ve completed adding weight scaling functionality to the existing record linkage framework.Matching records are determined by assigning a [...] [?]

Code Spotlight: Analyzing token frequencies

(10.Jul. 15:48)

I’d like to read a text file and store the frequency of each word in it into a database. Memory is fast, database is slow. At the two extremes, we have:1) I don’t use any memory, for each word I read, I query the database to learn it’s frequency, and update it in the database.Problem: Very Inefficient2) Everything [...] [?]

Phase3 Complete

(10.Jul. 15:48)

Now that Phase3 is ready for review, we have added weight scaling functionality to patient matching module. In fact, I have both versions of weight scaling implemented (Framework A and B). This week, I will be performing performance tests this week to determine if there is noteworthy performance difference between these two approaches. 3. Runtime Component, operational:  [...] [?]

Birkac hafta once izlemistim bu video‘yu, Turkiye’de internet alaninda girisimcilik ne durumda diye merak ediyordum. Silikon Vadisi’nden dondugum icin herseye yabanci gozuyle, elestirel olarak baktigimdan olsa gerek birden aklima geliverdi, oysa ilk izledigimde beni bu kadar rahatsiz etmemisti: itiraf.com gibi sitelerin kurucusu Ersan Ozer’e soruyorlar, “Internet uzerinden yatirim yapmak isteyen fikir sahiplerine nasil bir yol izlemelerini tasiye [...] [?]

Barcodes

(10.Jul. 19:04)

Imagine what you could do if we had establish standards on certain products regarding barcodes. Mobile devices are becoming ubiquitous, and they are not just phones any more, they have computing capabilities and internet connection. This opens a plethora of opportunities to make our lives easier. Case 1: What if product barcodes were easily recognizable by our [...] [?]

CloudCamp

(26.Jun. 01:16)

I attended CloudCamp at San Francisco, it was an “unconference” about cloud computing. It was so exciting to be there among 300 developers, enterpreneurs and businessman. Being in Silicon Valley is one of the best parts of my U.S. experience, you can feel the innovation that is going on when you see all these passionate people talking [...] [?]
