#artificialintelligence

The candidate will work within the technology team to develop, apply, and design novel machine learning (ML) algorithms with the ultimate aim of discovering therapeutic antibodies from next-generation sequencing (NGS) datasets. The candidate will be involved in multiple projects spanning our oncology, neuroscience, and infectious disease programmes. You will be responsible for the growth and development of our ML product roadmap. This will initially focus on exploiting methods in natural language processing for antibody discovery and patient stratification, and exploring the latest advances in ML (in areas such as self-supervised learning) to extend our capabilities. You will contribute new algorithms and strategies to increase accuracy, explainability, and/or automation of our technology platform.


Suicidal Text Analysis Using NLP

#artificialintelligence

It is estimated that each year many people, most of whom are teenagers and young adults die by suicide worldwide. Suicide receives special attention with many countries developing national strategies for prevention. It is found that, social media is one of the most powerful tool from where we can analyze the text and estimate the chances of suicidal thoughts. Using nlp we can analyze twitter and reddit texts monitor the actions of that person. The most difficult part to prevent suicide is to detect and understand the complex risk factors and warning signs that may lead to suicide.


Microsoft AI news: Making AI easier, simpler, more responsible

#artificialintelligence

We are excited to bring Transform 2022 back in-person July 19 and virtually July 20 - 28. Join AI and data leaders for insightful talks and exciting networking opportunities. Today is a big day for AI announcements from Microsoft, both from this week's Build conference and beyond. But one common theme bubbles over consistently: For AI to become more useful for business applications, it needs to be easier, simpler, more explainable, more accessible and, most of all, responsible. Responsible AI is actually at the heart of a lot of today's Build news, John Montgomery, corporate vice president of Azure AI, told VentureBeat. Most notable is Azure Machine Learning's preview of a responsible AI dashboard, which brings together capabilities in use over the past 18 months, such as data explorer, model interpretability, error analysis, counterfactual and causal inference analysis, into a single view.


Development and internal validation of a machine-learning-developed model for predicting 1-year mortality after fragility hip fracture - BMC Geriatrics

#artificialintelligence

Fragility hip fracture increases morbidity and mortality in older adult patients, especially within the first year. Identification of patients at high risk of death facilitates modification of associated perioperative factors that can reduce mortality. Various machine learning algorithms have been developed and are widely used in healthcare research, particularly for mortality prediction. This study aimed to develop and internally validate 7 machine learning models to predict 1-year mortality after fragility hip fracture. This retrospective study included patients with fragility hip fractures from a single center (Siriraj Hospital, Bangkok, Thailand) from July 2016 to October 2018. A total of 492 patients were enrolled. They were randomly categorized into a training group (344 cases, 70%) or a testing group (148 cases, 30%). Various machine learning techniques were used: the Gradient Boosting Classifier (GB), Random Forests Classifier (RF), Artificial Neural Network Classifier (ANN), Logistic Regression Classifier (LR), Naive Bayes Classifier (NB), Support Vector Machine Classifier (SVM), and K-Nearest Neighbors Classifier (KNN). All models were internally validated by evaluating their performance and the area under a receiver operating characteristic curve (AUC). For the testing dataset, the accuracies were GB model = 0.93, RF model = 0.95, ANN model = 0.94, LR model = 0.91, NB model = 0.89, SVM model = 0.90, and KNN model = 0.90. All models achieved high AUCs that ranged between 0.81 and 0.99. The RF model also provided a negative predictive value of 0.96, a positive predictive value of 0.93, a specificity of 0.99, and a sensitivity of 0.68. Our machine learning approach facilitated the successful development of an accurate model to predict 1-year mortality after fragility hip fracture. Several machine learning algorithms (eg, Gradient Boosting and Random Forest) had the potential to provide high predictive performance based on the clinical parameters of each patient. The web application is available at www.hipprediction.com . External validation in a larger group of patients or in different hospital settings is warranted to evaluate the clinical utility of this tool.

Google's Text-to-Image AI Can Make Any Wacky Image You Can Imagine

#artificialintelligence

Google has a new text-to-image AI that the company says beats the competition. Called Imagen, the program takes in text -- for example, "a photo of a Persian cat wearing a cowboy hat and red shirt playing a guitar on a beach" -- and outputs a result. Imagen can produce images that are photorealistic or an artistic rendering. Google's website for Imagen let's people people select text to change the resulting image. Imagen follows other text-to-image generators such as DALL-E, VQ-GAN CLIP and Latent Diffusion Models.
