I've been in the education business for decades as a senior lecturer, trainer and CEO. When people ask me about the biggest challenge that learners face, the first thing that comes to mind is that learners see training as something they "have to do." Now, let's think for a moment about this. How did we get here? Why aren't we talking about "want to do" or "happy to have the opportunity to do?"

This video will help you leverage the power of TensorFlow to perform advanced image processing. TensorFlow has been gaining immense popularity over the past few months, due to its power and simplicity to use. This video will help you leverage the power of TensorFlow to perform advanced image processing. This course is a continuation of the Intro to Computer Vision course, building on top of the skills learned in that course. In this course, you'll dive deeper as we cover more advanced computer vision concepts.

Cohere Inc., an AI startup founded by University of Toronto alumni that uses natural language processing to improve human-machine interactions, has raised US$125 million as it looks to open a new office in Silicon Valley, the Globe and Mail reports. The latest financing round, led by New York-based Tiger Global Management, comes only five months after Cohere secured $US40 million in venture capital financing, according to the Globe. Cohere's software platform helps companies infuse natural language processing capabilities into their business using tools like chatbots, without requiring AI expertise of their own. The company originated in a 2017 paper co-authored by CEO Aidan Gomez, who interned at the Google Brain lab of deep learning pioneer and University Professor Emeritus Geoffrey Hinton, a Cohere investor. Cohere's other co-founders are alumnus Nick Frosst, who also worked with Hinton at Google, and Ivan Zhang, a former U of T computer science student.

For building any product, whether it includes ML or not, the first step is to identify the problem you're trying to solve. ML is a great tool for solving some problems, but there are many where it's best to start simpler. In this post, let's consider working for a company building a hypothetical product for automatically transcribing university lectures. We're going to build an automatic speech recognition (ASR) system which is tuned to work well for lectures -- this is something that definitely needs machine learning at its core. The product team have decided to start small and focus initially on just Physics lectures as a proof of concept.

In this position paper, we study interactive learning for structured output spaces, with a focus on active learning, in which labels are unknown and must be acquired, and on skeptical learning, in which the labels are noisy and may need relabeling. These scenarios require expressive models that guarantee reliable and efficient computation of probabilistic quantities to measure uncertainty. We identify conditions under which a class of probabilistic models -- which we denote CRISPs -- meet all of these conditions, thus delivering tractable computation of the above quantities while preserving expressiveness. Building on prior work on tractable probabilistic circuits, we illustrate how CRISPs enable robust and efficient active and skeptical learning in large structured output spaces.

This paper describes the principle of "General Cyclical Training" in machine learning, where training starts and ends with "easy training" and the "hard training" happens during the middle epochs. We propose several manifestations for training neural networks, including algorithmic examples (via hyper-parameters and loss functions), data-based examples, and model-based examples. Specifically, we introduce several novel techniques: cyclical weight decay, cyclical batch size, cyclical focal loss, cyclical softmax temperature, cyclical data augmentation, cyclical gradient clipping, and cyclical semi-supervised learning. In addition, we demonstrate that cyclical weight decay, cyclical softmax temperature, and cyclical gradient clipping (as three examples of this principle) are beneficial in the test accuracy performance of a trained model. Furthermore, we discuss model-based examples (such as pretraining and knowledge distillation) from the perspective of general cyclical training and recommend some changes to the typical training methodology. In summary, this paper defines the general cyclical training concept and discusses several specific ways in which this concept can be applied to training neural networks. In the spirit of reproducibility, the code used in our experiments is available at \url{https://github.com/lnsmith54/CFL}.

Whale sharks can carry up to 300 babies at once--at different fetal stages and from different fathers. Zebra sharks experience "virgin birth." These are but a mere sampling of the decade's most fascinating shark discoveries. Some 500 known species of these toothy fish ply our planet's waters, ranging from bite size to bus size, and scientists are still becoming acquainted with most of them. Since 2000, when scientists discovered shark populations were collapsing around the world, research on sharks has ramped up across many fields of study, from paleontology to neuroscience to biomechanics.
