    This is by far the greatest course that I had on my entire life about computers. I work with full flight simulators for pilot training and many things that I learnt here became so clear for me... We see many systems in a very superficial way due to those abstraction levels and with those classes I can see what's behind the scene, what's going on in a deeper way.
    Thank you, guys. Thank you very much for sharing all this knowledge and in a way so simple and easy to understand. You're the best!!!
    And I'm recommending the channel for everybody I know that likes computer science on any level of understanding!

    For anyone who's interested, there's a (relatively) recent system called YOLO: You Only Look Once. Version 2 came out less than a year ago, if I remember right, and basically it uses computer vision techniques to classify many different objects in a scene in real-time video. As in, it's fast enough to fairly accurately detect and label many different objects in an arbitrary scene 24 times per second (24fps is a standard video frame rate). It's super interesting! :D

      Only the current frame, also you use in general, downloaded pre-trained models for weights, so you can start detecting things easily, you can add if want new detection, but of course it takes a lot of work, real time HD video needs around the GPU power of the GTX 1080 Ti, depending on the complexity of the weights, but you can trans-code a video, with the labels added on them, and watch later the final results.

      Shame no one answered before. Anyway, can be both. Python can be used in production and in testing (Really good libraries for complex computer vision like convolutional neural networks, object segmentation and so on). However when really high control over performance is needed, be it memory or computing speed, a low level language like c or c++ are used. Hope that helped :D

    Self driving cars often (also) use LIDAR, which has the great advantage of knowing distances, so the car is able to see in 3d. The (biggest) exception to this is Tesla, which decided that normal cameras work just fine, to which I say sure, but why not make it even better?

    • @sirtripalot2770
      @sirtripalot2770 6 років тому +5

      Good quality LIDAR sensors needed for automotive applications are expensive. One of Tesla's goals was to ship all of their cars with the hardware needed for automated driving, long before their cars were capable of automated driving. Shipping the initial cars without this feature but with LIDAR might have been too expensive to be feasible.
      Using this approach, Tesla collected millions of miles of consumer data about typical driving conditions. This treasure trove of data enables them to understand under what conditions what sensors fare poorly and gives a large test set to compare algorithms on.
      I don't know if Tesla made the right decision. They might have problems getting their system working in urban areas or other challenging environments without the more detailed data that LIDAR provides, but the low cost of Telsa's sensor package enabled them to use consumers to collect data for Tesla, and that is a significant advantage for Tesla's engineering design team.

    Convolution just happened to pop out from nowhere. In case you are wondering, convolution is the operation that maps a set of values (also called N-tuple where N stands for the quantity of elements) to another set of values.
    Very simple example:
    _1,2,3,4_ is a 4-tuple
    _+1,+1,+2,+2_ is a simple convolution
    _2,3,5,6_ is a 4-tuple as result of applying the above convolution
