mlnet-predict 1.0.1

MLNetPredict

MLNetPredict is a .NET tool for predicting various machine learning tasks using ML.NET. It supports multiple scenarios including classification, regression, forecasting, recommendation, and image/text classification.

Purpose

The mlnet-cli or mlnet model builder tools are designed to output strongly-typed model files and project files, which require the project to be built in order to be used. The purpose of this library is to execute predictions based on ML.NET models and output files without needing to modify the project. It allows for predictions to be made directly from input files.

Features

• Classification: Predict categories for given inputs.
• Regression: Predict continuous values.
• Forecasting: Predict future values based on historical data.
• Recommendation: Provide recommendations based on user/item interactions.
• Image Classification: Classify images into predefined categories.
• Text Classification: Classify text data into predefined categories.

Installation

To install the MLNetPredict tool, use the following command:

dotnet tool install --global mlnet-predict

Usage

Basic Usage

mlnet-predict <model-path> <input-path> [options]

• model-path: Path to the directory containing the .mlnet model file.
• input-path: Path to the input file or directory.

Options

• -o, --output-path: Path to the output directory (optional).
• --has-header: Specify [true|false] if the dataset file(s) have a header row.
• --separator: Specify the separator character used in the dataset file(s).

Example Commands

Classification

mlnet-predict models/GithubIssues files/github-issue/input.csv --has-header true

Regression

mlnet-predict models/TaxiFarePrediction files/taxi-fare/input.csv

Forecasting

mlnet-predict models/HourlyEnergyConsumption files/hourly_energy_consumption/input.json

Recommendation

mlnet-predict models/MovieRecommendation files/movie-recommendation/input.csv

Image Classification

mlnet-predict models/ImageClassification files/images/

Text Classification

mlnet-predict models/TextClassification files/texts/input.csv --has-header true

Prerequisites

Before running predictions, ensure that your ML.NET model and consumption code are properly generated. Use the following commands to create your models:

Example for Classification

mlnet classification --dataset "files/github-issue/issues.tsv" --label-col "Area" --train-time 120 --output "models" --name "GithubIssues" --log-file-path "./models/GithubIssues/logs.txt"

Example for Regression

mlnet regression --dataset "files/taxi-fare/taxi-fare-train.csv" --label-col "fare_amount" --validation-dataset "files/taxi-fare/taxi-fare-test.csv" --has-header true --name "TaxiFarePrediction" --train-time 120 --output "models" --log-file-path "./models/Sales/logs.txt"

Testing

Unit tests for the tool are available in the MLNetPredict.Tests namespace. Use the following command to run the tests:

dotnet test
