oid
|
oid
|
Database object ID
|
template_name
|
name
|
Template name of the machine learning model, which determines the interfaces invoked for training and prediction. Currently, only rlstm is implemented.
|
model_name
|
name
|
Model name. Each model corresponds to a set of parameters, training logs, and model coefficients in the AI engine online learning process. The name must be unique.
|
datname
|
name
|
Name of the database served by the model. Each model is specific to a single database. This parameter determines data used for training.
|
ip
|
name
|
IP address of the host where the AI engine is deployed
|
port
|
integer
|
Listening port number of the AI engine
|
max_epoch
|
integer
|
Maximum number of iterations in an epoch
|
learning_rate
|
real
|
Learning rate of model training. The default value 1 is recommended.
|
dim_red
|
real
|
Number of model feature dimensions whose retention is reduced
|
hidden_units
|
integer
|
Number of neurons in the model's hidden layer. If the model cannot be converged for a long time, increase the value of this parameter.
|
batch_size
|
integer
|
Size of a batch in each iteration. It is recommended that the size be greater than or equal to the total training data volume to accelerate model convergence.
|
feature_size
|
integer
|
Length of the model feature, which is used to trigger retraining. This parameter is automatically updated after model training and does not need to be specified.
|
available
|
boolean
|
Whether the model is converged. This parameter does not need to be specified.
|
Is_training
|
boolean
|
Whether the model is being trained. This parameter does not need to be specified.
|
label
|
"char"[]
|
Target task of the model.
- S: startup time
- T: total time
- R: rows
- M: peak memory
Currently, {S, T} or {R} is recommended due to model performance restrictions.
|
max
|
bigint[]
|
Maximum value of each task label of the model, which is used to trigger retraining. This parameter does not need to be specified.
|
acc
|
real[]
|
Accuracy of each model task. This parameter does not need to be specified.
