How do I measure the FLOPS my C# app uses?

Microsoft's Parallel Programming whitepaper describes situations that are optimal under various FLOPS thresholds, and that the FLOPS rate is a decision point as to when a certain implementation should be used. How do I measure FLOPS in my…

TensorFlow Object Detection API - determining FLOPS and number of Parameters

I have trained a custom SSD-MobileNetV2-FPN-Lite (320x320) from the TensorFlow Model zoo (TF2) and would like to know how many trainable parameters and FLOPs this network has. Does anyone know how to determine this?

What is the purpose of decreased FLOPs and parameter size if they are not for increased speed?

CNN algorithms like DenseNet DenseNet stress parameter efficiency, which usually results in less FLOPs. However, what I am struggling to understand is why this is important. For DenseNet, in particular, it has low inference speed. Isn't the purpose…

Is there a Pythonic implicits provision like in Scala? i.e. for FLOP counting

For an existing Python project, I need to introduce the "cross cutting" non-functional concern of FLOP counting so I can compute the performance in GFlop per second for that application. In Scala, I could solve this by having an implicit parameter…
