The power of data analytics
NVIDIA Jetson TX2, a 64-bit arm board equipped with 256 CUDA cores (Pascal architecture), has arrived at the home during the holiday season. I was so lucky having the board together with the development kit for only 300 Eur, including the shipping fee (from UK to NL) due to the educational discount (the normal price … Read moreGPU Inference at Edge: NVIDIA Jetson TX-2
My key takeaway: these 3 books agree on one thing: in the age of cutting-edge technology implementation like AI, social media; social science (i.e., the knowledge about how we understand interpersonal interaction) is needed more than ever today. Lee accentuates that jobs related to understanding human such as caregivers will have an important role in … Read moreBook review: AI Super Powers, Social Physics, Sensemaking
I was so lucky visiting the annual Big Data Expo @ Utrecht, the Netherlands on 19-20 September 2018 (https://www.bigdata-expo.nl/en) Here are some presentations I could capture:1. HOW TABLEAU ENABLED ABN AMRO TO VISUALIZE BIG DATA EFFICIENTLY (https://www.dropbox.com/sh/piazgsw9esw8dsl/AAAjjdjNNQFO0AbDRGyVns6ya?dl=0)2. HOW TO LET AN ELEPHANT DANCE; IMPLEMENTATION OF A DATA LAKE IN NEAR REAL-TIME AT A DUTCH INSURER … Read moreBig Data Expo NL
I just realized the newest version of MySQL (version 8.0) supported oracle-based “analytic function”, meanwhile his sister MariaDB had those two years ago.
In the previous post, the flexibility given by data science tools greatly reduces the performance, i.e., the execution speed. Fortunately, Dataiku, a data science tool, provides multiple ways to aggregate big data: 1) using the built-in building blocks; 2) using a custom R script with the built-in I/O blocks; or3) using an independent custom R … Read moreDataiku: flexible data science tools
Very often I need to verify whether a video containing certain keywords that I am looking for. That is very difficult to be done unless I watch the entire video or download the subtitle. However, most videos do not have a subtitle inside. I then found out the transcription services on the Internet but the … Read moreGoogle Cloud Speech API
Data science tools such as Rapidminer, Dataiku, and KNIME offer so much flexibility and provide easy-to-understand building blocks that abstract data processing functions. It allows data analysts implementing a business case quickly. However, it comes with a price: slowing down the execution speed due to variable transfer between tasks. Here is the trial. Aggregating 100 … Read moreFlexibility vs. Speed
Although I knew this service for a while, I just recently put attention on 2 “serverless” notebook services on the cloud: Google Colab and Microsoft Azure Notebooks. Here are my short reviews. <<Google colab>> 1. only support python (currently 3.6.7 and 2.7.15). you can build the packages through pip directly from the notebook. no way … Read moreGoogle Colab vs. Microsoft Azure notebook
This is why every organization engages artificial intelligence & machine learning. Once they have an “extensively trained” model that has a very good performance, they start selling it. Example: I tried Google Vision API to detect vehicle plates. The accuracy is amazing! Put many CCTVs on the roads, feed the image streams, predict the plate … Read moreGoogle Cloud Vision API to detect vehicle plate number
Two other popular data processing platform in the IT world are explored, i.e., DMX-h and SPSS Modeler. 1) DMX-h I was an extensive user of this beast software in 2009-2012. It is an amazing ETL platform, I used to process terabytes of chunked files which was completed in a short time (compared to a relational … Read moreSyncsort DMX-h & IBM SPSS Modeler
