In this paper we analyze and compare different movement sensors: micro-chip gesture-ID, leap motion, noitom mocap, and specially developed sensor for tapping and foot motion analysis. The main goal is to evaluate the accu-racy of measurements provided by the sensors. This study presents rele-vance, for instance, in tremor/Parkinson disease analysis as well as no touch mechanisms for activation and control of devices. This scenario is especially interesting in COVID-19 scenario. Removing the need to touch a surface, the risk of contagion is reduced.

Inductive biases are crucial in disentangled representation learning for narrowing down an underspecified solution set. In this work, we consider endowing a neural network autoencoder with three select inductive biases from the literature: data compression into a grid-like latent space via quantization, collective independence amongst latents, and minimal functional influence of any latent on how other latents determine data generation. In principle, these inductive biases are deeply complementary: they most directly specify properties of the latent space, encoder, and decoder, respectively. In practice, however, naively combining existing techniques instantiating these inductive biases fails to yield significant benefits. To address this, we propose adaptations to the three techniques that simplify the learning problem, equip key regularization terms with stabilizing invariances, and quash degenerate incentives. The resulting model, Tripod, achieves state-of-the-art results on a suite of four image disentanglement benchmarks. We also verify that Tripod significantly improves upon its naive incarnation and that all three of its "legs" are necessary for best performance.

Evaluate the completeness of reporting of prognostic prediction models developed using machine learning methods in the field of oncology. We conducted a systematic review, searching the MEDLINE and Embase databases between 01/01/2019 and 05/09/2019, for non-imaging studies developing a prognostic clinical prediction model using machine learning methods (as defined by primary study authors) in oncology. We used the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) statement to assess the reporting quality of included publications. We described overall reporting adherence of included publications and by each section of TRIPOD. Sixty-two publications met the inclusion criteria.

If robots are ever to achieve autonomous motion comparable to that exhibited by animals, they must acquire the ability to quickly recover motor behaviors when damage, malfunction, or environmental conditions compromise their ability to move effectively. We present an approach which allowed our robots and simulated robots to recover high-degree of freedom motor behaviors within a few dozen attempts. Our approach employs a behavior specification expressing the desired behaviors in terms as rank ordered differential constraints. We show how factoring these constraints through an encoding template produces a recipe for generalizing a previously optimized behavior to new circumstances in a form amenable to rapid learning. We further illustrate that adequate constraints are generically easy to determine in data-driven contexts. As illustration, we demonstrate our recovery approach on a physical 7 DOF hexapod robot, as well as a simulation of a 6 DOF 2D kinematic mechanism. In both cases we recovered a behavior functionally indistinguishable from the previously optimized motion.

Machine learning (ML) is a rapidly advancing field with increasing utility in health care. We conducted a systematic review and critical appraisal of ML applications in vascular surgery. MEDLINE, Embase, and Cochrane CENTRAL were searched from inception to March 1, 2021. Study screening, data extraction, and quality assessment were performed by two independent reviewers, with a third author resolving discrepancies. All original studies reporting ML applications in vascular surgery were included. Publication trends, disease conditions, methodologies, and outcomes were summarized. Critical appraisal was conducted using the PROBAST risk-of-bias and TRIPOD reporting adherence tools. We included 212 studies from a pool of 2235 unique articles. ML techniques were used for diagnosis, prognosis, and image segmentation in carotid stenosis, aortic aneurysm/dissection, peripheral artery disease, diabetic foot ulcer, venous disease, and renal artery stenosis. The number of publications on ML in vascular surgery increased from 1 (1991–1996) to 118 (2016–2021). Most studies were retrospective and single center, with no randomized controlled trials. The median area under the receiver operating characteristic curve (AUROC) was 0.88 (range 0.61–1.00), with 79.5% [62/78] studies reporting AUROC ≥ 0.80. Out of 22 studies comparing ML techniques to existing prediction tools, clinicians, or traditional regression models, 20 performed better and 2 performed similarly. Overall, 94.8% (201/212) studies had high risk-of-bias and adherence to reporting standards was poor with a rate of 41.4%. Despite improvements over time, study quality and reporting remain inadequate. Future studies should consider standardized tools such as PROBAST and TRIPOD to improve study quality and clinical applicability.

Specialized webcams that support Windows Hello are still, surprisingly, rare. Microsoft's secure-login system using fingerprint, biometric, and facial recognition technology is, after all, a unique feature of Windows 10 and Windows 11. It makes sense users would want to pair a desktop PC or older laptop with a Windows Hello-compatible camera in order to get its convenient security benefits. You might think that Microsoft's just-announced Modern Webcam would be an option, but, alas, it offers no Windows Hello support! That omission is even weirder given that Microsoft's Windows 10 21H1 release prioritizes external, Windows Hello-enabled webcams over the integrated laptop camera.

AI and ML will become truly transformational in our everyday lives in 2020. Aiding their rise will be the ever-growing cloud ecosystem and the move of ever more business-critical workloads feeding seemingly unstoppable growth. We'll also see changes in the global pecking order among the big players, as Chinese companies reorder the hierarchy in high growth markets. Change may be constant, but we believe 2020 is going to be a uniquely fascinating year! Operational workloads move to cloud and embrace AI and ML: Businesses will expedite the move of their operational data away from legacy providers like Oracle and SAP to cloud-native database management solutions.

Machine learning (ML) and artificial intelligence (AI) are becoming very useful technologies in cybersecurity. However, before you can model, validate, and visualize security data that will actually be useful, you need to prepare the data properly for input. This can be a difficult and complicated process – something data scientists wrestle with often. More than just traditional data preparation, which includes cleansing the data and de-duping, ML algorithms often require numerical rather than standard text input. The challenge is finding an efficient and accurate way to convert your data to numerical values that can be consumed by the ML model or algorithm.

Adobe is rather proud of its Sensei Artificial Intelligence (AI), as it continues to leverage it through its Creative Cloud ecosystem. The company just released more updates to Lightroom CC and Lightroom Classic photo editing applications. The Enhanced Details algorithm is new to the Lightroom family and Adobe Camera raw. The AI is enhanced to look closer at the pixel level and allow you to increase resolution by 30%. This provides much better overall detail as well as a better color rendering of your images.
