Our sole purpose as data scientists is to create value from data. More specific to machine learning (ML), we use algorithms to learn from data so that we can recognize patterns and use them to build generalizable models that ultimately benefit the top or bottom lines. That benefit--or value--is defined by the need that is driving our work. If working for a biotech company, that need might be to discover a new treatment. In marketing, value might come from a model that attributes revenue-generation to specific marketing programs.

At present, object recognition studies are mostly conducted in a closed lab setting with classes in test phase typically in training phase. However, real-world problem is far more challenging because: i) new classes unseen in the training phase can appear when predicting; ii) discriminative features need to evolve when new classes emerge in real time; and iii) instances in new classes may not follow the "independent and identically distributed" (iid) assumption. Most existing work only aims to detect the unknown classes and is incapable of continuing to learn newer classes. Although a few methods consider both detecting and including new classes, all are based on the predefined handcrafted features that cannot evolve and are out-of-date for characterizing emerging classes. Thus, to address the above challenges, we propose a novel generic end-to-end framework consisting of a dynamic cascade of classifiers that incrementally learn their dynamic and inherent features. The proposed method injects dynamic elements into the system by detecting instances from unknown classes, while at the same time incrementally updating the model to include the new classes. The resulting cascade tree grows by adding a new leaf node classifier once a new class is detected, and the discriminative features are updated via an end-to-end learning strategy. Experiments on two real-world datasets demonstrate that our proposed method outperforms existing state-of-the-art methods.

The Image Recognition Technology Is, Usually, Associated with an Array of Security and Surveillance-Related Uses and the Rapidly Developing Autonomous Vehicle Niche. Can Image Recognition Apps Help Businesses in Other Verticals? With Reuters' predictions for the not-so-far-off year of 2022 being in the region of a hefty $43-57 billion, Image Recognition is one big lure for AI outfits, and, simultaneously, a lot of hope for businesses and organizations that depend upon it for their survival and success. These include entities as diverse, as manufacturers of autonomous cars and security systems, national nature parks, border security forces, and companies that produce drones. Be it monitoring the state of a much cherished rainforest or sending drones to remote oil rigs to check if all one's assets are in one piece, almost all of the widely known uses of Image Recognition seem to be related to security and surveillance.

Even though early experiments in computer vision started in the 1950s and it was first put to use commercially to distinguish between typed and handwritten text by the 1970s, today the applications for computer vision have grown exponentially. By 2022, the computer vision and hardware market is expected to reach $48.6 billion. It is such a part of everyday life you likely experience computer vision regularly even if you don't always recognize when and where the technology is deployed. Here is what computer vision is, how it works and seven amazing examples in practice today. What is Computer Vision (CV)?

Google will use its powerful algorithms to let users rove their photos for text inside an image. Its new feature, slated to be rolled out in Google Photos, will allow users to search text that appears in photos and then, more importantly, copy and paste that text into a note or document using Google Lens -- its image recognition technology. In a tweet to venture capitalist Hunter Walk, Google acknowledged the feature which he noted had been turned on in his account. Google photos just got a lot smarter. The company's AI can now look through your library and pull out text that appear in images.

The lack of adequate training data is one of the major hurdles in WiFi-based activity recognition systems. In this paper, we propose Wi-Fringe, which is a WiFi CSI-based device-free human gesture recognition system that recognizes named gestures, i.e., activities and gestures that have a semantically meaningful name in English language, as opposed to arbitrary free-form gestures. Given a list of activities (only their names in English text), along with zero or more training examples (WiFi CSI values) per activity, Wi-Fringe is able to detect all activities at runtime. In other words, a subset of activities that Wi-Fringe detects do not require any training examples at all.

Security products incorporating artificial intelligence techniques may reduce the workload for human analysts, taking over the time-consuming job of correlating information sources and mining voluminous logs to uncover suspicious patterns of activity. Vendors, seeing the hype around AI, are quick to slap the label on almost any technology for a cutting-edge veneer. AI and machine learning techniques detect patterns in data and use those patterns to make predictions about the future. But those models are only as good as the data used to train them. Make sure it's clear how the security system's models were created.

For over 50 years, researchers have been trying to teach computers to read music notation, referred to as Optical Music Recognition (OMR). However, this field is still difficult to access for new researchers, especially those without a significant musical background: few introductory materials are available, and furthermore the field has struggled with defining itself and building a shared terminology. In this tutorial, we address these shortcomings by (1) providing a robust definition of OMR and its relationship to related fields, (2) analyzing how OMR inverts the music encoding process to recover the musical notation and the musical semantics from documents, (3) proposing a taxonomy of OMR, with most notably a novel taxonomy of applications. Additionally, we discuss how deep learning affects modern OMR research, as opposed to the traditional pipeline. Based on this work, the reader should be able to attain a basic understanding of OMR: its objectives, its inherent structure, its relationship to other fields, the state of the art, and the research opportunities it affords.

Don't look at the clock! Now tell me: How much time has passed since you first logged on to your computer...READ MORE An efficient pattern recognition of a lion makes perfect evolutionary sense. If you see a large feline shape moving in some nearby brush, it is unwise to wait until you see the yellows of the lion's eyes before starting to run up the nearest tree. You need a brain that quickly detects entire shapes from fragments of the total picture and provides you with a powerful sense of the accuracy of this recognition. One need only think of the recognition of a new pattern that is so profound that it triggers an involuntary "a-ha!" to understand the degree of pleasure that can be associated with learning.
