Initialization of numerical optimization

Beim Durchlaufen dieses Codes:
seed = 1
controls = list(
states = 3,
sdds = "gamma",
horizon = 500,
fit = list("runs" = 100)
)
controls %<>% set_controls
data = prepare_data(controls, seed = seed)
data %>% summary
data %>% plot
model = fit_model(data, ncluster = 1, seed = seed) %>%
decode_states %>%
compute_residuals
summary(model)
model %<>% reorder_states(state_order = 1:3)
compare(model)
model %>% plot("ll")
model %>% plot("sdds")
wird der 3. Status leider nicht richtig erkannt. Ich habe dasselbe auch mit 1000 Runs einmal ausgeführt, geändert hat sich am Ergebnis allerdings nichts.
The function set_f
should
Implement function fixed_initialization
:
Implement a function that captures and returns trace of numerical optimization. For example, the progressive function values, parameter values, steps, gradients, Hessians from nlm()
.
The function set_optimizer
should
Replace any set.seed()
calls by a call to ino_seed()
with a status message if verbose = TRUE
.
Implement unit tests for subset_argument()
, currently missing.
summary()
output for global optima to simplify the filteringsubset_last
performs worseFor the em
optimizer, one run converged to value = 248
. Explain.
After $optimize()
and then $clear("all")
, $print()
throws error. Check!
Random initialization of f
with optimizer
based on inputs runs
, lower
and upper
(as vectors?) and sampler
("normal", "uniform"
)
Function that measures the optimization time of different methods and returns overview.
Maybe density plots? With brackets to compare medians? And remove log-scale, this is misleading.
