Tree summary with shape inference

**Using `model.summary(array=input_array)` `serket` can evaluate the shape propagation without evaluating the model , by using `jax` no-flop shape inference operations.**

print(model.summary(array=x))

🔘 Filtering by masking

Filter by value

# get model negative values
negative_model = model.at[model<0].get()

# Set negative values to 0
zeroed_model = model.at[model<0].set(0)

# Apply `jnp.cos` to negative values
cosined_model = model.at[model<0].apply(jnp.cos)

Filter by field name

# get model layer named `l1`
l1_model = model.at[model == "l1" ].get()

# Set `l1` values to 0
zeroed_model = model.at[model == "l1" ].set(0)

# Apply `jnp.cos` to `l1` 
cosined_model = model.at[model == "l1" ].apply(jnp.cos)

Filter by field type

# get all model `Linear` layers
l1_model = model.at[model == sk.nn.Linear ].get()

# Set `Linear` layers to 0
zeroed_model = model.at[model == sk.nn.Linear ].set(0)

# Apply `jnp.cos` to all `Linear` layers 
cosined_model = model.at[model == sk.nn.Linear ].apply(jnp.cos)

Filter by mixed masks

# Set all `Linear` bias to 0
mask = (model == sk.nn.Linear) & (model == "bias" )
zero_bias_model = model.at[mask].set(0.)
