Descent

An accessible perspective on essential machine learning conceptsToday, we will delve into three crucial concepts in Machine Learning: Linear Regression, Cost Function, and Gradient Descent. These concepts form the foundation of many Machine Learning algorithms. Initially, I decided against writing an article on these topics because they are so widely covered. However, I have changed my mind because understanding these concepts is essential for understanding more advanced topics like Neural Networks (that I plan on…

A high-level introduction to optimisation in 7 minutesPhoto by vackground.com on UnsplashTraining a deep learning model involves taking a set of model parameters and shifting these towards some optimum set of values. The optimum set of values is defined as the point at which the model becomes the best version of itself with respect to performing some task.Intuitively, this can be thought of as when we learn a new skill. For example, if you decide to take up a new sport, the likelihood is that you’ll be pretty bad the…

Thanks largely to streaming services like Netflix bombarding us with so much content covering virtually ever base, even the most demanding of true crime fanatics will find themselves regularly satiated by what the platform is putting out there. Thanks to the title, though, subscribers know exactly what to expect from Kai the Hatchet-Wielding Hitchhiker. The documentary only dropped yesterday, but it hasn’t wasted any time in instantly cleaving through the competition to become one of the most popular titles on the…

In a video shared exclusively with NME, Survivorman host Les Stroud takes viewers through his contributions to upcoming VR game Survivorman VR: The Descent. In the 18-minute video, Stroud vlogs his way through the development of Survivorman VR: The Descent – from suiting up for motion capture sessions to delivering his lines for the game and pretending he’s “in the Avengers” in front of a green screen. Additionally, Stroud also explains his role in ensuring the game is realistic, and scenarios or options within the…

Visualize the differences and similarities between gradient descent, gradient descent with momentum, RMSprop, and AdamPhoto by Kristen Munk from Pexels: https://www.pexels.com/photo/photo-of-person-walking-on-unpaved-pathway-2599546/If you are like me, equations do not speak for themselves. To understand them, I need to see what they do with a concrete example. In this blog post, I apply this visualization principle to popular optimization algorithms used in machine learning.Nowadays, the Adam algorithm is a very popular…

How to characterize the radial distortion of a camera-lens pair, based on a simple modelPhoto by Charl Folscher on UnsplashConsumer-grade cameras and lenses are cheap and ubiquitous. Unfortunately, unlike their industrial counterparts, they were not designed to be used as tools for precise measurements in computer vision applications.Among the various types of distortion, the most visible one affecting a low-grade camera and lens is radial distortion. Radial distortion is a nonlinearity between the viewing angle of an…

Last Updated on November 29, 2022 The gradient descent algorithm is one of the most popular techniques for training deep neural networks. It has many applications in fields such as computer vision, speech recognition, and natural language processing. While the idea of gradient descent has been around for decades, it’s only recently that it’s been applied to applications related to deep learning. Gradient descent is an iterative optimization method used to find the minimum of an objective function by updating values…

The 10-year-old gene-editing tool known as CRISPR is indispensable for engineering plants, tailoring lab animals, and probing basic biology. But there’s a caveat when it is used to tweak human genes: Unlike lab mice, which are usually inbred and genetically identical, people’s genomes differ individually and by ancestry. These ancestry differences mean CRISPR doesn’t always edit some genomes as intended, particularly in people of African descent, whose genomes…

via Saban Films His time at the top of the Hollywood A-list may have come to an end a long time ago, but Mel Gibson is hardly struggling to find work. In fact, On the Line marks his seventh feature film appearance of the year, and his 11th in total since the beginning of 2020. Almost every single one of them has been a bargain basement action thriller, though, a category writer and director Romuald Boulanger’s latest falls firmly into. On Rotten Tomatoes, On the Line holds a measly nine percent score, while a 45…

Mahindra Thar is still one of the most popular 4×4 SUVs in Indian market. Ever since its launch in India we have seen several videos where the SUV is seen doing off-roading. The main reason behind its popularity are the rugged looks, off-road capabilities and attractive price. It is still one of the most affordable 4×4 SUV one can buy in India. There are several videos related to Mahindra Thar available online. Some of them are modifications related while others are off-roading and drag racing. Here we have a video…
