As a society, we’re in a constant struggle to control uncertainty and predict the unknown. Quite often, we think of scientific fields and theories as being separate from each other. But a more careful investigation can uncover the common thread that ties many of those together. From ChatGPT, to Amazon’s Alexa, to Apple’s Siri, Data Science, and Computer Science have become part of our lives. In the meantime, the demand for data scientists has grown, as the field has been increasingly called the “sexiest profession.” This book attempts to specifically cover this gap in literature between Data Science, Machine Learning and Artificial Intelligence (AI). How was uncertainty approached historically, and how has it evolved since? What schools of thought exist in philosophy, mathematics, and engineering, and what role did they play in the development of Data Science? It uses the history of Data Science as a stepping stone to explain what the future might hold.

This practical introduction covers all the aspects and features you need to be successful with Salesforce reports and dashboards. Author David Carnes, chairman and chief evangelist for OpFocus, shows executives, end users, and report and dashboard superusers what analytics are possible, which features report writers should ask to be enabled, and which settings and permissions system administrators need to activate.

Decision support systems are developed for integrated pest and disease management and nutrition management using open-source technologies as Java, Android, and low-cost hardware devices like Arduino micro controller. This text discusses the techniques to convert agricultural knowledge in the context of ontology and assist grape growers by providing this knowledge through decision support system. Many solutions are available for sensing environmental parameters. For using environmental readings for decision support, sensors need to be boarded on fields and be connected to computerized systems for measurement recording and manipulation. Arduino is an open- source platform for implementing wireless sensor networks. Using Arduino microcontroller, sensor inputs are read and sent to server using some connectivity technique like Wi-Fi, Zigbee or GPRS. Programs can be written to read inputs and to write outputs to connected devices using Arduino IDE. Instructions can be sent on microcontrollers of Arduino kit to get the work done. ESP8266 is a Wi-Fi module which can be used for transferring sensor outputs to server machines through GPRS or Zigbee. It can be mounted on Arduino microcontroller and programmed using AT commands.
