AgentsPredictorWorker

from AID.selector.interface import AgentsPredictorWorker

Step 14: Ensemble Scoring (Candidate Generation). Generates probability predictions for all learning agents using a target dataset (typically Out-of-Time samples). This step creates the raw evidence base used by all subsequent evaluation workers in the Selection Phase.

Parameters

inputs : AgentsPredictorInput

Custom scoring configuration. If None, resolves defaults from ‘test.ml’ state.

**kwargs : dict

Additional parameters passed to the Predictor worker.

Inputs full schema can be obtained by ctx.workers.agents_predictor.spec with main params:

`inputs == None`	→	pipeline data context
`data != None`	→	custom data for agent predictions

Returns

AgentsPredictorWorker

The populated instance of AgentsPredictorWorker.

Populates attributes into the worker context:

`model`	→	ctx.workers.agents_predictor
`inputs`	→	ctx.workers.agents_predictor.spec
`result`	→	ctx.workers.agents_predictor.result
`state`	→	ctx.workers.agents_predictor.state
`stats`	→	ctx.workers.agents_predictor.stats
`fitter`	→	ctx.workers.agents_predictor.fitter

Registers data into the datasets context:

`predictions`	→	ctx.datasets.predictions.test.agent1
`predictions`	→	ctx.datasets.predictions.test.agent2
`predictions`	→	ctx.datasets.predictions.test.agent3
`predictions`	→	ctx.datasets.predictions.test.agent4
`stats`	→	ctx.datasets.stats.agents.prediction

Examples

Defining the Project Context (Control Plane) & Project Scope:

import aidflow as aid

ctx = aid.ProjectContext()

ctx.genesis(
    project      = 'test',
    input_data   = 'test.csv',
    target       = 'target',
    yy_mm        = 'decision_date',
    yy_mm_format = '%Y-%m-%d'
)
ctx.params()

Worker → Model → Fitter

Accessing worker’s inputs schema → parameters & types (shown in the display output):

ctx.workers.agents_predictor.spec

Accessing model’s fitter options and schema → parameters & types (shown in the display output):

ctx.workers.agents_predictor.fitters

Executing workers with defaults → auto provided by the context:

ctx.flow.process('data')        # 1. process workers 0-3 → data load - data stability
ctx.flow.process('encoding')    # 2. process workers 4-9 → train and apply encoding to train and test samples
ctx.flow.process('training')    # 3. process workers 10-13 → agents trainining on encoded train sample
ctx.workers.agents_predictor()  # 4. test sample prediction by agents

Once worker has been executed, thus its main model has been built, we have access to all populated attributes.

worker   = ctx.workers.agents_predictor
inputs   = worker.spec.inputs
result   = worker.result
state    = worker.state
features = worker.features
params   = worker.params
stats    = worker.stats
fitter   = worker.fitter  # jump to chosen internal fitter
...

Model → Fitter

Once worker has been executed, we can obtain internal fitter state and its parametrization (shown in the display output):

ctx.workers.agents_predictor.fitter

The fitted fitter provides all populated attributes.

fitter    = ctx.workers.agents_predictor.fitter
params_   = fitter.params
stats_    = fitter.stats

In the experimenting phase, when various parametrization settings might be under testing (note that internal fitter API (fx_config) can vary with respect to chosen fitter):

cfg = dict(
    target = 'target2',
    preprocess = True
)
agents_predictor = ctx.workers.agents_predictor(fx_config = cfg)

Attributes

All worker attributes return None prior its execution.
