Companies Going 'All In' on AI, Appen Study Says

#artificialintelligence

AI budgets are up significantly over the past year as companies compete to survive and grow market share during the global pandemic, according to Appen, which published its State of AI and Machine Learning report this week. The study also detected a correlation between AI budget size and the likelihood that AI projects will actually be deployed on the one hand, and budgets and the use of external data providers on the other. Now in its seventh year, Appen's State of AI seeks to generate a broad snapshot of AI investments across the United States. The company contracted with Harris Poll to investigate various aspects of AI investments and project management at 500 companies, all of which had at least 100 employees. The growth in AI budgets was perhaps the most compelling result to come out of the study, which had a margin of error of 5%. According to the study, the number of companies with budgets ranging from $500k to $5 million increased by 55% compared to last year.

Xilinx launches Kria chips to handle AI for edge applications

#artificialintelligence

Xilinx has introduced its Kria programmable chips and boards for holding AI applications at the edge of the network. This should come in handy for visual applications like smarter cameras. San Jose, California-based Xilinx, which is in the process of being acquired by Advanced Micro Devices (AMD) for $35 billion, has a group of products dubbed the Kria portfolio of adaptive system-on-module offerings for AI at the edge. These are production-ready small form factor embedded boards that enable rapid deployment in edge-based applications. Coupled with a complete software stack and prebuilt, production-grade accelerated applications, Kria adaptive modules are a new method of bringing adaptive computing to AI and software developers.


Artificial Intelligence in Radiology: Current Applications and Future Technologies

#artificialintelligence

For lung nodules, CNN have been shown to distinguish between benign and malignant classifications at a higher performance than traditional CADx systems due to their ability to function at higher degrees of noise tolerance (Hosny et al. 2018; Nasrullah et al. 2019). Furthermore, in a study done on patients with non-small cell lung cancer, AI CADx algorithms were able to use CT images to significantly predict which cancers contained EGFR mutations, informing on potential treatment with Gefitinib (Bi et al. 2019). Deep learning algorithms have also been trained to accurately classify prostate cancer on Magnetic Resonance Imaging (MRI), which can promote early treatment as well as decrease the number of unnecessary prostate biopsies and prostatectomy procedures performed (Bi et al. 2019). An additional study reported an AI system that was able to use MRI imaging to accurately generate brain tumour classification differentials at a level that exceeded human performance. The algorithm generated the correct diagnosis in one of its top three differentials 91% of the time, outperforming academic neuroradiologists (86%), fellows (77%), general radiologists (57%), and radiology residents (56%) (Rauschecker et al. 2020).


IBM Research Engineer Abhishek Bhandwaldar On His Machine Learning Journey

#artificialintelligence

Analytics India Magazine got in touch with Abhishek Bhandwaldar, Research Engineer at IBM to understand his machine learning journey. Abhishek has a Master's in Computer Science from the University of North Carolina. "It is important to have a basic understanding of the different topics in the field to make sure you end up in the area you feel most passionate about," says Abhishek. Abhishek: My introduction to AI was through video games. Then, I read about how'Deep Blue' devised long-term strategies and beat an expert opponent in chess.


Confusion Matrix for Machine Learning

#artificialintelligence

Have you been in a situation where you expected your machine learning model to perform really well but it sputtered out a poor accuracy? You've done all the hard work – so where did the classification model go wrong? How can you correct this? There are plenty of ways to gauge the performance of your classification model but none have stood the test of time like the confusion matrix. It helps us evaluate how our model performed, where it went wrong and offers us guidance to correct our path.


4 Top Benefits and Challenges of AI in Cybersecurity - The Next Scoop

#artificialintelligence

In this article, we're going to discuss machine learning and artificial intelligence in cybersecurity. We'll look at the benefits and challenges of AI, their role in cybersecurity, and how criminals can abuse this technology. Cyberattacks have been rising in frequency and scale for a few years now. We saw a sharp jump since the start of the notorious pandemic. With data security in more danger than ever, it's no surprise that more and more companies are turning to artificial intelligence in the hope of getting more powerful digital protection from hackers, phishers, and other cyber criminals.


Watch: Sharjah prisons use artificial intelligence to pre-empt unnatural behaviour by inmates

#artificialintelligence

The system can detect any movement that the prisoner makes, such as violence, quarrels, or anger etc. The face, hand movements or body movements can be analysed and a warning can be sent out about a prisoner even before he or he is about to commit an illegal act. It also studies and analyses facial expressions for the purpose. The Smart Monitoring' system uses AI and machine-learning algorithms.


Radiology: Artificial Intelligence

#artificialintelligence

Although AI has generated excitement for the future of radiology, hopes for an automated radiological future have been dashed by reports of poor generalization of deep learning models. Models trained on images from one hospital can perform poorly when tested on images from a different one, often related to differences in disease prevalence between hospitals. Perhaps more concerning, deep learning models trained on chest radiographs (CXRs) with an underrepresentation of females have been shown to be biased for a variety of thoracic diseases; not surprisingly, these models performed better on CXRs of male patients. Biases and underrepresentation in datasets was one of several topics covered at this year's Conference on AI, Ethics, and Society, organized by the Association for the Advancement of Artificial Intelligence (AAAI) and the Association for Computing Machinery (ACM). Because AI models can reflect biases in the datasets used to develop them, detecting the presence of biases and addressing them is an important task.


A Bot that Bird Watches so You Don't Have To

#artificialintelligence

If you have ever tried to watch a live nest camera hoping to observe a falcon or other interesting bird, you may have had the experience of opening the live stream and seeing an empty nest. Not sure how long you should wait for the bird to return? In this article, I will describe my final project for the 12-week Metis Data Science Bootcamp that I attended January–March 2021. My project was aimed at automating nest monitoring for the Nottingham Trent University Falcon Cam. Using deep learning and automation tools, I designed a method for 24-hour bird detection that serves as an infrastructure upon which a Twitter bot or other notification system can be built to notify users when the bird enters or leaves the nest.
