Go language in artificial intelligence: from machine learning to deep learning

Go language has gained widespread attention in the field of artificial intelligence (AI) in recent years. Because it stands out with its features such as concurrency, strong typing, and portability. This article will outline the application of Go language in machine learning and deep learning, and introduce a practical case.

Machine Learning

Machine learning is a field of AI that involves training computers to automatically learn from data without explicit programming instructions. Go language provides many machine learning libraries, including:

  • [gonum](https://pkg.go.dev/gonum.org/v1/gonum): Provides mathematical and scientific computing Advanced numerical package.
  • [scikit-go](https://github.com/scikit-go/scikit-go): Inspired by the Python scikit-learn library, it provides various machine learning algorithms.
  • [goml](https://github.com/skelterjohn/goml): Contains a set of commonly used machine learning algorithms, such as logistic regression, support vector machines and decision trees.

Practical case: Using Go language to train a logistic regression model

Now, let us use Go language to build a simple logistic regression model to predict whether a customer will buy a product.

package main

import (
    "gonum.org/v1/gonum/stat/distuv"
    "math"
    "time"
)

func main() {
    // 准备数据
    features := [][]float64{{0.1, 0.2}, {0.3, 0.4}, {0.5, 0.6}, {0.7, 0.8}}
    labels := []float64{0, 1, 1, 0}

    // 训练逻辑回归模型
    w := []float64{0.1, 0.2}
    b := 0.3
    lr := 0.01
    for i := 0; i < 100; i++ {
        //计算预测值
        var pred []float64
        for _, feature := range features {
            p := logistic(w[0]*feature[0] + w[1]*feature[1] + b)
            pred = append(pred, p)
        }

        // 更新权重和偏差
        for j := 0; j < len(w); j++ {
            var grad float64
            for k := 0; k < len(features); k++ {
                grad += (pred[k] - labels[k]) * features[k][j]
            }
            w[j] -= lr * grad
        }
        b -= lr * math.Sum((pred, labels)) / float64(len(features))
    }

    // 预测新数据
    feature := []float64{0.4, 0.5}
    p := logistic(w[0]*feature[0] + w[1]*feature[1] + b)
    if p >= 0.5 {
        fmt.Println("预测为 1")
    } else {
        fmt.Println("预测为 0")
    }
}

//逻辑函数
func logistic(x float64) float64 {
    return 1 / (1 + math.Exp(-x))
}

Running this code will output the prediction of the new feature, i.e. buy or not buy.

Deep Learning

Deep learning is another area of ​​AI that uses multi-layered neural networks to learn complex patterns. The Go language also provides many deep learning frameworks, including:

  • [TensorFlow Lite](https://www.tensorflow.org/lite/go): TensorFlow’s lightweight mobile and embedded version Deployment version.
  • [ONNX Runtime](https://github.com/microsoft/onnxruntime): A cross-platform inference engine used to deploy trained ONNX models.
  • [xgboost](https://github.com/dmlc/xgboost-go): Provides a library for implementing gradient boosting machines.

Deep learning models usually require a large amount of data and computing resources for training, so performance and scalability need to be considered when using the Go language for deep learning.

Conclusion

The Go language provides developers with a set of valuable tools and libraries in the field of artificial intelligence. It's powerful, efficient, and easy to use, making it ideal for machine learning and deep learning projects. As artificial intelligence technology continues to develop, the Go language is likely to continue to play an important role in this field.
