Keras broke the ice for me. The design of NNs used to take me a while to understand. It felt mechanic and meaningless. I was struggling hard to understand why adding or subtracting layers would help or hurt my models. I was trudging through tf documentation and honestly… I was very close to giving up.
I built my first ANN, got better with keras, graduated to tf, built my first U-net and got more confidence. I think anyone that really criticizes keras doesn’t understand that it is like criticizing training wheels for a bike.
You gotta learn to walk before you can run. You gotta learn baby nets before you are building monster segmentation models on recurrent convolutional neural nets. It takes time to understand the concepts and data flow.
training wheels are horrible btw
it's much better to train kids with "pedal-less" bikes and then graduate them to pedals without training wheels, much easier to adapt to gaining balance etc.
So, either you have not recently taught a kid to ride a bike or you are just trolling.
So, I will counter your high ceiling with the low floor plan. The more a person rides a bike tw’s or not the better they will be at riding a bike. The tw’s get you riding more often and logging in the hours.
You may be right about balance being a skill you develop without tw’s but the hours they will spend failing and falling down discourages the kids then they don’t want to play anymore.
I think you misunderstood me. In France they have those bikes for kids without pedals called "draisiennes" (I don't know what it is in English).
Kids on these bikes have no training wheels and they just "stroll" with them, lift their legs, and get used to manage the balance at speed. My friend's kids who got used to it like that were able to pedal on their first "real bike" (with pedals) first time, without any training wheels.
It makes the transition *a lot* easier apparently.
Yeah, Keras was sort of useful and sort of annoying, but training wheels just suck. What's worst is when your kid falls while using training wheels. One a balance bike, you know you're unstable. On training wheels, your kid has false faith and isn't prepared for the tipover... especially if your kid is, at that moment, entranced with your scintillating lecture about the superiority of PyTorch.
