Artificial neural networks (ANNs) for material modeling have received significant interest. We recently reported an adaptation of ANNs based on Boltzmann machine (BM) architectures to an ansatz of the multiconfigurational many-electron wavefunction, designated neural-network quantum state (NQS), for quantum chemistry calculations. Here, this study presents its extended formalism to a quantum algorithm that enables the preparation of the NQS through quantum gates. The descriptors of the ANN model, which are chosen as occupancies of electronic configurations, are quantum-mechanically represented by qubits. Our algorithm may thus bring potential advantages over classical sampling-based computation employed in the previous studies.

Brain tumors are one of the most challenging diseases for clinical researchers, as it causes severe harm to patients. The brain is a central organ in the human body, and minor damage to this organ could affect the correct functioning of the human body. Brain tumors can lead to irreversible and dysfunctional damage to patients, including memory and vision loss. For these reasons, medical studies have, for a long time, focused on the study of the brain and its diseases, including brain tumors. Computer studies have contributed to medical research by offering machine learning algorithms to classify medical analysis records as brain tumors or normal clinical conditions.

Noise is one of the primary quality-of-life issues in urban environments. While low-cost sensors can be deployed to monitor ambient noise levels at high temporal resolutions, the amount of data they produce and the complexity of these data pose significant analytical challenges. One way to address these challenges is through machine listening techniques, which are used to extract features in attempts to classify the source of noise and understand temporal patterns of a city's noise situation. However, the overwhelming number of noise sources in the urban environment and the scarcity of labeled data makes it nearly impossible to create classification models with large enough vocabularies that capture the true dynamism of urban soundscapes In this paper, we first identify a set of requirements in the yet unexplored domain of urban soundscape exploration. To satisfy the requirements and tackle the identified challenges, we propose Urban Rhapsody, a framework that combines state-of-the-art audio representation, machine learning, and visual analytics to allow users to interactively create classification models, understand noise patterns of a city, and quickly retrieve and label audio excerpts in order to create a large high-precision annotated database of urban sound recordings.

Today, MLOps offers a fairly robust framework for operationalizing AI, says Zuccarelli, who's now innovation data scientist at CVS Health. By way of example, Zuccarelli points to a project he worked on previously to create an app that would predict adverse outcomes, such as hospital readmission or disease progression. That meant creating a mobile app that was reliable, fast, and stable, with a machine learning system on the back end connected via API. As MLOps platforms mature, they accelerate the entire model development process because companies don't have to reinvent the wheel with every project, he says. And this means developing expertise in a wide range of activities, says Meagan Gentry, national practice manager for the AI team at Insight, a Tempe-based technology consulting company.

It is the new SOTA for text-to-image synthesis. Architecturally, it is actually much simpler than DALL-E2. It consists of a cascading DDPM conditioned on text embeddings from a large pretrained T5 model (attention network). It also contains dynamic clipping for improved classifier free guidance, noise level conditioning, and a memory efficient unet design. It appears neither CLIP nor prior network is needed after all.

In our previous post, we talked about how red AI means adding computational power to "buy" more accurate models in machine learning, and especially in deep learning. We also talked about the increased interest in green AI, in which we not only measure the quality of a model based on accuracy but also how big and complex it is. We covered different ways of measuring model efficiency and showed ways to visualize this and select models based on it. Maybe you also attended the webinar? If not, take a look at the recording where we also cover a few of the points we'll describe in this blog post.

Phil Hall is Chief Growth Officer at LXT, an emerging leader in global AI training data that powers intelligent technology. Earlier this year, we introduced our first executive survey, The Path to AI Maturity. The report highlights that investment in artificial intelligence is strong at mid-to-large US organizations, and 40% rate themselves at the three highest levels of AI maturity, having achieved operational to transformative implementations. The new survey by research firm Reputation Leaders included 200 senior executives (two-thirds C-suite) with AI experience at companies with annual revenue of over $100 million and more than 500 employees – and details the impact that AI investment is having across organizations of varying revenue levels and industries. As part of the survey, executives placed their companies on the Gartner AI Maturity Model.

It's since been an exciting time for startups as entrepreneurs continue to discover use cases for computer vision in everything from retail and agriculture to construction. With lower computing costs, greater model accuracy and rapid proliferation of raw data, an increasing number of startups are turning to computer vision to find solutions to problems. However, before founders begin building AI systems, they should think carefully about their risk appetite, data management practices and strategies for future-proofing their AI stack. TechCrunch is having a Memorial Day sale. You can save 50% on annual subscriptions for a limited time.

There are many ways to get started with studying machine learning. I have previously written a lot about how to design your own curriculum and roadmap as an alternative to taking courses. This approach allows you to pick and choose free, or low-cost, resources from across the internet that suit both your learning style and budget. However, when you are just starting out on the beginning of your journey into machine learning it can often be useful to follow at least a short course that will guide you through the basic concepts first. This will give you a good foundational overview of the field and it will make it easier to design your own learning path and then continue on with deeper self-directed learning.

The bleak and all-too-common spectacle of roadkill was upsetting to Vedant Srinivas -- particularly when his uncle and cousin's beloved German Shepherd-Rottweiler mix was fatally hit by a car. More importantly, the losses made the high school student wonder if he could do something about it. What if Srinivas could stop the pet owners' broken hearts, save wildlife and deflect the economic impacts caused by the collisions? This month his efforts were rewarded. The sophomore from Eastlake High School in Sammamish, Wash., brought home a $5,000, first place grand award for the category of Environmental Engineering from the Regeneron International Science and Engineering Fair (ISEF).
