We’re taking a break from our portfolio series and million sample simulations to return to a subject that we haven’t discussed of late despite its featured spot in this blog’s name—options. In this post, we’ll look at the buy-write (BXM) and put-write (PUT) indices on the S&P 500, as conceived, ... Read More

Feed: Big Data Made Simple. Author: Sharafudheen Mangalad. If you have this doubt whether Java can be used for Artificial Intelligence (AI), then, many brilliant Java developers in one voice will say a “YES”. These developers also have the opinion that Java is one of the best programming languages after Python for developing Artificial Intelligence solutions. One thing you need to realise is, there is no individual language only to develop Artificial Intelligence solutions. In spite of that, the existing tools help developers achieve great results when developing AI Solutions.Today, you’ll see the prevalence of Artificial Intelligence in most of ... Read More

Feed: Microsoft Azure Blog. Author: Chaitanya Bangur. Genomics is foundational to the development of targeted therapeutics and precision medicine. Advances in DNA sequencing technologies has driven a revolution in genomics-based research and is helping facilitate better understanding of human biology and disease conditions. This expanded knowledge is leading to the proliferation of personalized medicine strategies to prevent, diagnose, and treat diseases. The trend will continue to accelerate in the coming decade as use of genomics information becomes central to clinical decision support and healthcare delivery. Sequencing genomes at the population level will be required to decipher the genomic fingerprint of ... Read More

Feed: Planet MySQL; Author: Kristian Köhntopp; Completing the data lifecycle is often harder than originally expected: Deleting data can cost sometimes way more than inserting it in the first place. MySQL Partitions can offer a way out. We have an earlier post on the subject.A sample table, and a problem statement Let’s define a kind of log table, to which data is added with an auto_increment id value and some data. #! /usr/bin/env python3 from time import sleep from random import randint from multiprocessing import Process import click import MySQLdb import MySQLdb.cursors db_config = dict( host="localhost", user="kris", passwd="geheim", db="kris", cursorclass=MySQLdb.cursors.DictCursor, ...

Feed: Actian. Author: Pradeep Bhanot. Abraham Lincoln is quoted as saying, “If I had 8 hours to chop down a tree, I would spend 6 sharpening my axe.”  Spending 75% of the allotted time on preparation may seem like a lot, but in fact, most industry observers report that preparing data for business analysis or machine learning is indeed 70 to 80% of the time spent by data scientists and analysts.The data preparation pipeline consists of the following steps Access the data. Ingest (or Fetch) the data. Cleanse the data. Format the data. Combine the data. And finally, Analyze the ... Read More

Feed: Redis Labs. Author: Alex Milowski. During the 2020 wildfires in California, I, along with millions of others, have been constantly checking the PurpleAir website to monitor the air quality. In addition to looking for clean air to breathe, I was curious about how PurpleAir aggregated data from its sensors and was excited to discover that it had an API for accessing its data. It seemed a perfect opportunity to demonstrate the power of Redis as a database deployed using Kubernetes. In the past, some of my research focused on exposing geospatial data on the web. For this project, I ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Sharmistha Chatterjee. Importance of C++ in Data Science and Big Data Introduction and Motivation – Why C++ C++ is ideal for dynamic load balancing, adaptive caching, and developing large big data frameworks, and libraries. Google’s MapReduce, MongoDB, most of the deep learning libraries listed below have been implemented using C++. Scylla known for its ultra-low latency and extremely high throughput is coded using C++ acts as a replacement to Apache Cassandra and Amazon DynamoDB. With some of the unique advantages of C++ as a programming language, (including memory management, performance characteristics, and systems programming), it definitely serves as one of the most efficient tools for developing fast scalable Data Science and Big Data libraries. Further, Julia (a compiled and interactive language – ... Read More

Feed: Planet MySQL; Author: Kristian Köhntopp; MySQL uses connection and config parameters from a number of possible sources. The easiest way to find out where it is looking for config files is to run $ mysql --help | grep cnf order of preference, my.cnf, $MYSQL_TCP_PORT, /etc/my.cnf /etc/mysql/my.cnf /Users/kkoehntopp/homebrew/etc/my.cnf ~/.my.cnfAs can be seen, my version of the MySQL client checks in this order /etc/my.cnf /etc/mysql/my.cnf /Users/kkoehntopp/homebrew/etc/my/cnf ~/.my.cnf The cnf file is a file in dot-ini syntax, so you have [groups] and each group contains lines with key = value pairs. Which groups are read? $ mysql --help | grep "groups are" ... Read More
