Hi! I just had a quick look over Picard and had some thoughts + constructive criticism as someone who uses keras + hyperopt.
the json syntax you use is very cumbersome.. soo many levels of depth. It's also not clear why you do/dont use the built-in keras json model configs.. in fact your project seems to have no relation at all to keras/hyperopt (other than assumably using it in the backend) and instead you just invented a new configuration format. In general, it feels like it'd take longer to write those config files than it would be to just write a keras model and some for loops or learn hyperopt itself.
I guess i'm saying that for me personally, this syntax seems too complex. just my constructive opinion :)
for instance, this really scares me for having just two layers:
{
"operators": {
...,
"feedforward": {
"#repeat": {
"operator": {
"#compose": [
{
"layer": "Dense",
"config": {
"output_dim": 512,
"activation": {
"&choice": {
"options": [
"relu",
"sigmoid"
]
}
}
}
},
{
"#optional": {
"layer": "Dropout",
"config": {
"p": {
"&uniform": {
"high": 0.6,
"low": 0.3
}
}
}
}
}
]
},
"+times": {
"&choice": {
"options": [
2,
3,
4,
5
]
}
}
}
}
}
}
}
