Feed: Redis Labs. Author: Chris Cheung. At RedisConf19, we officially released a new module called Redis Gears. You may have already seen some other modules by either Redis Labs or the community at large, but Gears will defy any expectations you have. It really pushes the limits of what is possible with modules. Gears scripts At first glance, Redis Gears looks like a general-purpose scripting language that can be used to query your data in Redis. Imagine having a few hashmaps in your Redis database with user-related information such as age and first/last name. Here is the execution breakdown for ... Read More

Feed: R-bloggers. Author: Graeme Keleher. My web scraping project explored the distribution of headline sentiment by news source. To do this, I scraped the Nasdaq latest market headlines page and applied sentiment analysis to the retrieved text. It should be noted that I only scraped one web page, but this page aggregates headlines from multiple sources. I wanted to see whether the language used by different news sources varies significantly as this information could be relevant to baseline sentiment scores in a trading strategy.  I used the Scrapy web crawling framework in Python to scrape the headlines. Because the page ... Read More

Feed: R-bloggers. Author: statcompute. Compared with other types of neural networks, General Regression Neural Network (Specht, 1991) is advantageous in several aspects. Being an universal approximation function, GRNN has only one tuning parameter to control the overall generalization The network structure of GRNN is surprisingly simple, with only one hidden layer and the number of neurons equal to the number of training samples. GRNN is always able to converge globally and won’t be trapped by local solutions. The training of GRNN is a simple 1-pass, regardless of the sample size, and doesn’t require time-consuming iterations. Since any projected value of ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Ann Rajaram. If you are a recent graduate or someone preparing for your first data scientist position, then here are some tips to help you ace your interview! Interview types: For core data scientist roles, you will have both technical and behavioral interviews. Some employers will have them as separate interviews, while some use the same time slot to do both. Lately a lot of initial phone screens use a combination of tech Qs apart from the traditional "resume walk-through" to narrow down the applicant list for round 2 interviews. So ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Shaily Baheti. Machine Learning Practitioners have different personalities. While some of them are “I am an expert in X and X can train on any type of data”, where X = some algorithm, some others are “Right tool for the right job people”. A lot of them also subscribe to “Jack of all trades. Master of one” strategy, where they have one area of deep expertise and know slightly about different fields of Machine Learning. That said, no one can deny the fact that as practising Data Scientists, we will have ... Read More

Feed: Planet PostgreSQL. In a lot of PostgreSQL environments, it’s common practice to protect user accounts with a password. Starting with PostgreSQL 10, the way PostgreSQL manages password-based authentication got a major upgrade with the introduction of SCRAM authentication, a well-defined standard that is a significant improvement over the current system in PostgreSQL. What’s better is that almost all PostgreSQL drivers now support this new method of password authentication, which should help drive further adoption of this method.While it may be easy to take advantage of SCRAM authentication in new PostgreSQL deployments, there are a few steps involved in upgrading ...
