These Algorithms Look at X-Rays--and Somehow Detect Your Race

WIRED

Millions of dollars are being spent to develop artificial intelligence software that reads x-rays and other medical scans in hopes it can spot things doctors look for but sometimes miss, such as lung cancers. A new study reports that these algorithms can also see something doctors don't look for on such scans: a patient's race. The study authors and other medical AI experts say the results make it more crucial than ever to check that health algorithms perform fairly on people with different racial identities. Complicating that task: The authors themselves aren't sure what cues the algorithms they created use to predict a person's race. Evidence that algorithms can read race from a person's medical scans emerged from tests on five types of imagery used in radiology research, including chest and hand x-rays and mammograms.


How Does AI Help You Search Better?

#artificialintelligence

AI technology has grown in leaps and bounds over the past few years, and one of its main implementations is internet search engines. From correcting misspelled words to predicting what a user wants to search for, AI has made searching the web so much easier. Google is the leader when it comes to the sheer volume of search queries that it handles. Naturally, it has implemented an AI-based algorithm that helps improve your search experience. Exactly how does AI do this?


How to do machine learning without an army of data scientists

#artificialintelligence

Jennifer Flynn had a problem. Shortly after joining LeadCrunch as a senior data scientist, she wanted to push out one small update of the company's software, which uses machine learning to find sales leads for its business customers. The data science team consisted of just five engineers, including her. That simple update took days and required help from the company's product development team, too. "It wasn't tenable," Flynn said, now LeadCrunch's principal data scientist.


A.I. Systems Diagnosing Sepsis: Is It Ready for Prime Time?

#artificialintelligence

Sepsis remains one of the most costly and deadly of medical conditions. Sepsis is not a disease per se, but a syndrome, a collection of signs and symptoms, that indicated the presence of an overwhelming infection. Many, if not all, severely ill patients with COVID-19 had viral sepsis. Bacterial causes are more common, but sepsis in all its microbial forms carries a high mortality. Academics have long tortured clinical hospital data to find some statistical means of identifying sepsis or its incipient signs, because early intervention is associated with better outcomes.


Machine Learning using Python Programming - CouponED

#artificialintelligence

Learn the core concepts of Machine Learning and its algorithms and how to implement them in Python 3 New Rating: 4.4 out of 54.4 (215 ratings) 32,564 students What you'll learn Description'Machine Learning is all about how a machine with an artificial intelligence learns like a human being' Welcome to the course on Machine Learning and Implementing it using Python 3. As the title says, this course recommends to have a basic knowledge in Python 3 to grasp the implementation part easily but it is not compulsory. This course has strong content on the core concepts of ML such as it's features, the steps involved in building a ML Model - Data Preprocessing, Finetuning the Model, Overfitting, Underfitting, Bias, Variance, Confusion Matrix and performance measures of a ML Model. We'll understand the importance of many preprocessing techniques such as Binarization, MinMaxScaler, Standard Scaler We can implement many ML Algorithms in Python using scikit-learn library in a few lines. Can't we? Yet, that won't help us to understand the algorithms. Hence, in this course, we'll first look into understanding the mathematics and concepts behind the algorithms and then, we'll implement the same in Python.


Automated Morphometric Analysis of the Hip Joint on MRI from the German National Cohort Study

#artificialintelligence

To develop and validate an automated morphometric analysis framework for the quantitative analysis of geometric hip joint parameters in MR images from the German National Cohort (GNC) study. A secondary analysis on 40 participants (mean age, 51 years; age range, 30–67 years; 25 women) from the prospective GNC MRI study (2015–2016) was performed. Based on a proton density–weighted three-dimensional fast spin-echo sequence, a morphometric analysis approach was developed, including deep learning based landmark localization, bone segmentation of the femora and pelvis, and a shape model for annotation transfer. The centrum-collum-diaphyseal, center-edge (CE), three alpha angles, head-neck offset (HNO), and HNO ratio along with the acetabular depth, inclination, and anteversion were derived. Quantitative validation was provided by comparison with average manual assessments of radiologists in a cross-validation format. High agreement in mean Dice similarity coefficients was achieved (average of 97.52% 0.46 [standard deviation]). The subsequent morphometric analysis produced results with low mean MAD values, with the highest values of 3.34 (alpha 03:00 o'clock position) and 0.87 mm (HNO) and ICC values ranging between 0.288 (HNO ratio) and 0.858 (CE) compared with manual assessments. These values were in line with interreader agreements, which at most had MAD values of 4.02 (alpha 12:00 o'clock position) and 1.07 mm (HNO) and ICC values ranging between 0.218 (HNO ratio) and 0.777 (CE). Automatic extraction of geometric hip parameters from MRI is feasible using a morphometric analysis approach with deep learning.


Data Science Vs Data Engineering

#artificialintelligence

People often confuse data science and data engineering, although this is not the case. Let us have a better understanding of this. Data science is a multi-disciplinary. It uses scientific techniques, procedures, algorithms, and technologies to extract information and insights from structured and unstructured figures. It then applies that knowledge and valuable insights across a variety of application areas.


Banking Needs To Prepare For Marketing's Data Arms Race

#artificialintelligence

Despite warnings for more than a decade, most financial institutions are unable to manage the data at their disposal or extract actionable insights, leaving money and opportunities on the table. To compete with fintech, big tech and the largest banks, financial institutions of all sizes will need to harness the power of data, making insight-driven decisions and delivering the level of experiences consumers and businesses have come to expect from the firms with the highest levels of data analytics maturity, like Amazon, Google, Facebook, Apple and others. In research done on behalf of Deluxe by the Digital Banking Report, it was found that many organizations have the ability to extract insights from various data sources, supporting foundational marketing decisions and creating segmented marketing programs. Where most organizations fall short, however, is in using data and artificial intelligence (AI) to power real-time decision-making throughout every aspect of the customer journey. The lack of data analytics maturity also hampers the ability create instantaneous learnings from marketing initiatives, using tools like machine learning (ML), that can improve marketing performance over time.


LumenVox Launches Next-Generation Automatic Speech Recognition Engine with Transcription

Want to avoid an insurrection or genocide? Disconnect AI from centralized databases now! As the power of AI grows and the internet plays an ever greater role in our physical realities, we must act decisively to put the protection of user data at the forefront of any new developments in online products and services. The consequences of failing to protect personal privacy online could be another insurrection or genocide. Artificial Intelligence has a key role to play in securing online privacy, despite all the recent news stories about AI in conjunction with the misuse of private data.
