Crowd Monitoring and Localization Using Deep Convolutional Neural Network: A Review

#artificialintelligence

Crowd management and monitoring is crucial for maintaining public safety and is an important research topic. Developing a robust crowd monitoring system (CMS) is a challenging task as it involves addressing many key issues such as density variation, irregular distribution of objects, occlusions, pose estimation, etc. Crowd gathering at various places like hospitals, parks, stadiums, airports, cultural and religious points are usually monitored by Close Circuit Television (CCTV) cameras. The drawbacks of CCTV cameras are: limited area coverage, installation problems, movability, high power consumption and constant monitoring by the operators. Therefore, many researchers have turned towards computer vision and machine learning that have overcome these issues by minimizing the need of human involvement. This review is aimed to categorize, analyze as well as provide the latest development and performance evolution in crowd monitoring using different machine learning techniques and methods that are published in journals and conferences over the past five years.


Janggu makes deep learning a breeze – IAM Network

IMAGE: The scientists Altuna Akalin (left) and Wolfgang Kopp (right) from the "Bioinformatics and Omics Data Science " group. Researchers from the MDC have developed a new tool that makes it easier to maximize the power of deep learning for studying genomics. They describe the new approach, Janggu, in the journal Nature Communications. Imagine that before you could make dinner, you first had to rebuild the kitchen, specifically designed for each recipe. You'd spend way more time on preparation, than actually cooking.


A TensorFlow Modeling Pipeline using TensorFlow Datasets and TensorBoard

#artificialintelligence

This article investigates TensorFlow components for building a toolset to make modeling evaluation more efficient. Specifically, TensorFlow Datasets (TFDS) and TensorBoard (TB) can be quite helpful in this task. While completing a highly informative AICamp online class taught by Tyler Elliot Bettilyon (TEB) called Deep Learning for Developers, I got interested in creating a more structured way for machine-learning model builders -- like me as the student -- to understand and evaluate various models and observe their performance when applied to new datasets. Since this particular class focused on TensorFlow (TF), I started to investigate TF components for building a toolset to make this type of modeling evaluation more efficient. In doing so, I learned about two components, TensorFlow Datasets (TFDS) and TensorBoard (TB), that can be quite helpful and this blog post discusses their application in this task.


Using AI to detect COVID-19 misinformation and exploitative content

#artificialintelligence

The COVID-19 pandemic is an incredibly complex and rapidly evolving global public health emergency. Facebook is committed to preventing the spread of false and misleading information on our platforms. Misinformation about the disease can evolve as rapidly as the headlines in the news and can be hard to distinguish from legitimate reporting. The same piece of misinformation can appear in slightly different forms, such as as an image modified with a few pixels cropped or augmented with a filter. And these variations can be unintentional or the result of someone's deliberate attempt to avoid detection.


Graphcore claims its M2000 AI computer hits 1 petaflop

#artificialintelligence

Graphcore, a U.K.-based company developing accelerators for AI workloads, this morning unveiled the second generation of its Intelligence Processing Units (IPUs), which will soon be made available in the company's M2000 IPU Machine. Graphcore claims this new GC200 chip will enable the M2000 to achieve a petaflop of processing power in an enclosure that measures the width and length of a pizza box. AI accelerators like the GC200 are a type of specialized hardware designed to speed up AI applications, particularly artificial neural networks, deep learning, and machine learning. They're often multicore in design and focus on low-precision arithmetic or in-memory computing, both of which can boost the performance of large AI algorithms and lead to state-of-the-art results in natural language processing, computer vision, and other domains. The M2000 is powered by four of the new 7-nanometer GC200 chips, each of which packs 1,472 processor cores (running 8,832 threads) and 59.4 billion transistors on a single die, and it delivers more than 8 times the processing performance of Graphcore's existing IPU products.


Best Stocks To Buy As Markets Rally Despite Elevated Volatility

#artificialintelligence

Major tech stocks drove the markets lower this morning, with Nasdaq NDAQ down by almost 0.5%. In contrast, the Dow was trading higher by 200 points buoyed by banking stocks like JP Morgan and Citigroup C, which have beaten street estimates on earnings this morning. Of course, by mid-morning, the Nasdaq had turned positive. More choppiness should be expected as more companies declare their quarterly results throughout the week. Our deep learning algorithms have gone through the data and used Artificial Intelligence ("AI") to help you spot the Top Buys for today.


The path to real-world artificial intelligence

#artificialintelligence

Artificial intelligence has made significant strides in recent years, but modern AI techniques remain limited, a panel of MIT professors and the director of the MIT-IBM Watson AI Lab said during a webinar this week. Neural networks can perform specific, well-defined tasks but they struggle in real-world situations that go beyond pattern recognition and present obstacles like limited data, reliance on self-training, and answering questions like "why" and "how" versus "what," the panel said. The future of AI depends on enabling AI systems to do something once considered impossible: Learn by demonstrating flexibility, some semblance of reasoning, and/or by transferring knowledge from one set of tasks to another, the group said. The panel discussion was moderated by David Schubmehl, a research director at IDC, and it began with a question he posed asking about the current limitations of AI and machine learning. "The striking success right now in particular, in machine learning, is in problems that require interpretation of signals--images, speech and language," said panelist Leslie Kaelbling, a computer science and engineering professor at MIT.
