Feed: Featured Blog Posts - Data Science Central. Author: Divya Singh. Deep Learning is a highly empirical domain which majorly focusses on fine-tuning the various parameters. The choice of these parameters defines the accuracy of the model. So, it becomes important to choose such parameters wisely. Choosing the parameters based on intuition might not work every time which can degrade the performance of the model drastically. Also, a considerable amount of time and effort will go in vain while selecting the values of parameters based on intuition. So, the methodological approach should be followed to select the optimal values of ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Bill Schmarzo. I suck at the NCAA March Madness® bracket selection process.  I let my personal biases get in the way of making decisions based upon the numbers.  I over-rate the well-known Big Ten conference and under-rate the lesser-known Mid Majors and fall in love with the most recent team I saw on TV win their conference tournament.  You see, I fall prey to all the common decision-making traps – recency bias, over-confidence, anchoring, risk aversion, framing – that doom my brackets from the very beginning.  (See the Appendix for more ...

Feed: Feed | Tractica. Author: . NVIDIA is not necessarily known for powering low power AI applications. Most of its artificial intelligence (AI) focus has been on powering high power cloud or data center applications, where its Tesla graphics processing unit (GPU) processors have largely led the market. However, over the last 12 months, NVIDIA has accelerated its reach beyond the data center and is now building its portfolio to service low power AI edge applications. When it comes to AI at the edge, NVIDIA has been focusing on the automotive sector with its Xavier platform and on robotics and ... Read More

Feed: Blog – ArangoDB. Author: Willi Goesgens. This is an update of the 2016 blog post How to put ArangoDB to Spartan-Mode. A lot of things have changed in the last years. We moved our API implementation from JavaScript to C++. ArangoDB now has a new (default) storage engine, namely RocksDB instead of MMFiles. RocksDB is a great storage engine. However, it also trades memory for speed. If you start with the default configuration you might end up with using much more memory for ArangoDB than expected. Therefore let’s focus on our new storage engine, and make a configuration to ... Read More
