A Guide to Analyzing Experimental Data

#artificialintelligence

Have you ever run an experimental study, or performed some A/B testing? If so, you should be familiar with the pre-analysis panic: how can you make the data reveal whether your experiment has worked? Every day -- in economics, public policy, marketing, and business analytics -- we face the challenges that come from running experiments and analyzing what comes out of them. As researchers -- who struggle with a clean and efficient experimental workflow ourselves -- we have decided to share with you a practical guide, complete with all the steps you need to follow when you want to analyze experimental data. We cannot promise that the journey will be short, but we assure you it will be fun!

How and Why Pharmaceutical Manufacturers Are Applying Artificial Intelligence

#artificialintelligence

Advances in the application of artificial intelligence (AI) are starting to have a significant impact on automation technologies used across industry--most notably with machine vision and analytics. And some of the more impactful applications of AI are happening in the pharmaceutical industries. It shouldn't be too surprising that the pharmaceutical industries are looking to optimize production with AI, considering that single batch values for some drugs can exceed $3 million. Yet, research indicates that this industry lags many others when it comes to using analytics to improve production. David Leitham, senior vice president and general manager, pharmaceuticals, at AspenTech.According to David Leitham, senior vice president and general manager, pharmaceuticals, at AspenTech (a supplier of AI software for industrial manufacturers), while other industries have been applying analytics and predictive capabilities to optimize performance and react rapidly to changes in demand, 87% of pharmaceutical industry executives admit their organizations have a poor digital culture.


Feature Engineering of DateTime Variables for Data Science, Machine Learning - KDnuggets

#artificialintelligence

DateTime fields require Feature Engineering to turn them from data to insightful information that can be used by our Machine Learning Models. This post is divided into 3 parts and a Bonus section towards the end, we will use a combination of inbuilt pandas and NumPy functions as well as our functions to extract useful features. Whenever I have worked on e-commerce related data, in some way or the other dataset contains DateTime columns. At the outset, this date field gives us nothing more than a specific point on a timeline. But these DateTime fields are potential treasure troves of data.


StreetLight Data Partnership Aims to Help Expand EV Chargers

#artificialintelligence

With electric vehicles slowly gaining momentum toward becoming the dominant form of transportation in the U.S., two startups have struck up a partnership to help cities and utilities figure out where to put more car chargers. StreetLight Data, which sells transportation data to local governments, will offer Volta Charging's PredictEV tool to its customers. The tool uses AI to generate suggestions about where electric charging infrastructure would be most useful -- an urban planning consideration that is becoming more important as more electric vehicles hit the streets. Today, electric vehicles make up only around 2 percent of new vehicles sold in the U.S., but that number is rising rapidly. In 2020, Pew Research found that the number of EVs sold in the country had more than tripled since 2016.


The Future of AI and Big Data: Three Concepts

#artificialintelligence

"We are probably in the second or third inning." Lo, a professor of finance at the MIT Sloan School of Management, and Ajay Agrawal of the University of Toronto's Rotman School of Management shared their perspective at the inaugural CFA Institute Alpha Summit in May. In a conversation moderated by Mary Childs, they focused on three principal concepts that they expect will shape the future of AI and big data. Lo said that applying machine learning to such areas as consumer credit risk management was certainly the first inning. But the industry is now trying to use machine learning tools to better understand human behavior.


AI Requires a Holistic Framework and Scalable Projects - InformationWeek

#artificialintelligence

Ever since I can remember, artificial intelligence has been the holy grail. Films have portrayed it, from BladeRunner to the more recent Her. In the meantime, business leaders promised it would revolutionize the workplace. In both cases, we've been presented with scenarios in which AI transforms the daily grind. Indeed, AI has been talked about as a scientific discipline since 1956.


Artificial Intelligence for IT Operations: an Overview

#artificialintelligence

Artificial intelligence for IT operations (AIOps) combines sophisticated methods from deep learning, data streaming processing, and domain knowledge to analyse infrastructure data from internal and external sources to automate operations and detect anomalies (unusual system behavior) before they impact the quality of service. Odej Kao, professor at the University of Technology Berlin, gave a keynote presentation about artificial intelligence for IT operations at DevOpsCon Berlin 2021. In data stream processing we frequently struggle to find sufficient amounts of data. On the other hand, in AIOps we have many different sources (e.g., metric, logs, tracing, events, alerts) with several Terabytes of data produced in a typical IT infrastructure per day. We utilize the power of these hidden gems to assist DevOps administrators and jointly with the AI-models improve the availability, security, and the performance of the overall system.


Public health agencies in Victoria's South West to roll out InterSystems's AI data platform

#artificialintelligence

Hospitals in Victoria's South West, including public health agencies under the South West Alliance of Rural Health and Barwon Health in Geelong, are set to roll out a data platform capable of real-time analysis using AI, machine learning, as well as business and clinical intelligence. The health organisations will be deploying the IRIS for Health platform by global tech provider InterSystems. The data platform, according to InterSystems's website, is specifically engineered to extract value from healthcare data. It is a standards-based platform that is able to read and write Health Level 7's Fast Healthcare Interoperability Resources (HL7 FHIR) for developing healthcare applications. It is also capable of ingesting, processing and storing transaction data "at high rates" while simultaneously processing high volume analytic workloads involving historical and real-time data. While the health providers have interconnected systems, including clinical and patient administration systems, specialist healthcare applications and data analytics solutions, they don't have a single data repository supporting real-time data analysis.
