  • A New Paradigm Of Object Detection: Using Transformers

    However, computer vision, so far, has been immune to the advent of transformers so far. DETR can be implemented in less than 50 lines with PyTorch. Now for the time, object detection is being looked at through the lens of transformers. A new model by the name Detection Transformers (DETR) was recently released by the AI wing of Facebook.

  • Fire detection for oil filled transformers - NFPA (fire) Code

    I am not sure about the reason for a heat/ smoke detector to cover an oil filled transformer. The oil is normally a non combustible (under definition of NFPA) product and transformers under many circumstances blow up at which point smoke detectors would be meaningless. I have never seen a transformer fire but I have seen them blow up.
