Image by author.Overcome LDA’s Shortcomings with Embedded Topic ModelsThe 2003 paper, Latent Dirichlet Allocation, established LDA as what is now probably the best known and most widely used algorithm for topic modeling (Blei et al. 2003). Yet despite its ubiquity and longevity, those experienced with LDA are familiar with its limitations. In addition to its instability, detailed below, LDA requires more than a little text pre-processing to obtain good results. Even putting aside the implementation details, LDA suffers…

Many medical exosuits are built to improve walking, but researchers at ETH Zurich might have a solution to improve your arm strength. They've developed the Myoshirt, a wearable arm exomuscle that can compensate for conditions and injuries affecting the upper body. The combination of vest and cuff uses sensors to detect your intended movements and cue a motor that shortens a cable running alongside your muscles. Effectively, you're getting a supplemental tendon that provides additional power and endurance for whatever…

VTOL (vertical take-off and landing) aircraft are coming but not anytime soon. Aircraft progress ranges from conceptual designs to complete prototypes and early test flights. But we’re a while off from commercial aviation. Further, a focus on the aircraft and the required regulations has overlooked the management of their journeys. I recently spoke with Corvin Huber, CEO, and CTO of Skyroads, to find out more, and it left me convinced that commercial electric VTOLs aren’t hitting the skies…

Deep beneath the waves there's a source of power quite unlike any other. To tap into it, Japanese engineers have constructed a true leviathan, a beast capable of withstanding the strongest of ocean currents to transform its flow into a virtually limitless supply of electricity.  Ishikawajima-Harima Heavy Industries – now known simply as IHI Corporation – has been tinkering with the technology for over a decade now, partnering with New Energy and Industrial Technology Development Organization (NEDO) in 2017 to put their…

Even as agriculture remains a priority sector accounting for the livelihoods of around 58 per cent of the country's population, adoption of technology in the sector is at a transitory juncture and faces several challenges across the value chain, according to a report. Though agriculture in India is at a transitory juncture, with a focus on integration of technologies for better operations, the sector faces several challenges across the value chain, said a report by PwC and FICCI. The report titled 'Redefining agriculture…

Researchers at the Indian Institute of Technology in Mandi have developed state-of-art solutions to enhance the reusability of radiofrequency spectrum which can overcome shortage and meet the growing demands of data communication in the future wireless communication applications. The findings of the team's work have recently been published in IEEE Transactions on Consumer Electronics, and other IEEE journals.According to the team, radio frequency waves or "spectrum" as they are known in the telecommunication field, are…

AI has numerous applications in the healthcare industry, and it continues to grow with technology advancements. However, this field also has some limitations that hold AI back from being integrated into the current healthcare systems. We will explore how you can overcome these challenges to boost healthcare with AI. Understand how and why AI comes up with specific results AI models become more complicated to deliver better outcomes. This complexity causes AI to work in a “black-box,” where it becomes harder to understand…
