# Factorization Machines Response Formats
Inference Formats

Amazon SageMaker AI provides several response formats for getting inference from the Factorization Machines model, such as JSON, JSONLINES, and RECORDIO, with specific structures for binary classification and regression tasks.

## JSON Response Format


Binary classification

```
let response =   {
    "predictions":    [
        {
            "score": 0.4,
            "predicted_label": 0
        } 
    ]
}
```

Regression

```
let response =   {
    "predictions":    [
        {
            "score": 0.4
        } 
    ]
}
```

## JSONLINES Response Format


Binary classification

```
{"score": 0.4, "predicted_label": 0}
```

Regression

```
{"score": 0.4}
```

## RECORDIO Response Format


Binary classification

```
[
    Record = {
        features = {},
        label = {
            'score’: {
                keys: [],
                values: [0.4]  # float32
            },
            'predicted_label': {
                keys: [],
                values: [0.0]  # float32
            }
        }
    }
]
```

Regression

```
[
    Record = {
        features = {},
        label = {
            'score’: {
                keys: [],
                values: [0.4]  # float32
            }   
        }
    }
]
```
