Convolutional Neural Networks (CNNs) | Deep Learning
CNNs are a go-to deep learning architecture for many computer vision tasks, from image classification to object detection and more. Here, we take a look at the basics, and see how they use biologically-inspired hierarchical feature extraction to do what they do.

Dijkstra's algorithm is a neat way of finding the minimum-cost path between any two nodes in a graph. Here we see briefly how can use it to optimize our path through a graph, and also explore why it performs as well as it does. Feel free to like, comment and subscribe if you appreciate what I do!
Einstein's Ladder Paradox; Simply Explained
Просмотров 9 тыс.Год назад
In special relativity, the ladder paradox (or, "barn-pole" paradox) occurs due to they symmetry of length contraction. Here we explore how this apparent paradox can be solved using the relativity of simultaneity. If you're interested in more special relativity content, check out the series below!

Solving Einstein's Twin Paradox

Many solutions have been proposed to Einstein's twin paradox, but many of them miss the vital reasons why the Earth twin is correct and the Spaceship twin is wrong.

    In 13:25 it was stated that maximizing ELBO also maximizes evidence and minimizes the KL divergence. However, you did not prove/show how can be this happen. Actually, I thought the evidence was a constant because when we gather a dataset of {x1, x2, ... xn}, p_theta(xi) is constant (when theta is constant)

    About Limitations at 13:55 , first bullet point, didn't you say that the model predicts an one-hot class per bounding box? doesn't that mean that each grid cell can actually contain up to B classes? thanks for the amazing explanation by the way

    Привет Hello. With the help of the “HYBRID gyroscope” you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,... I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)” where - the light travels 48000 meters in each arm, while it does not exceed the parameters 40/40/40 cm, and the weight is 4 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions. Einstein dreamed of measuring the speed of a train, an airplane - through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. (We are not looking for ether, we will see the work of gravitational quanta) The result is a «theory of everything» in a simple teaching device and a new tape measure for measuring the universe.

    Microphone volume levels - you have it too loud which is causing distortion and makes the video horrible to listen to. When you're quieter there's no distortion, it's only when you're louder. So turn the volume down. You should see Green, Yellow or Red for volume levels on your recording app. For sure you're in the red. Re edit the video with the volume reduced.

    Aether is a fluid, an incompressible fluid. It adheres to matter in order to couple light electromagnetic energy between Aether and matter, in doing so drag with earth as well as the interferometer, and hence to a static fringe pattern. However, as a liquid, Aether velocity remote from earth moves at a slower average velocity defined by the nearest planets and galaxies by a factor of 1/r.
