1200 pixels spectral datasets

In the Zip, spectral. npy was the average spectral data of red ginseng, mycotoxins and interference impurities, and label. npy was the corresponding label.  Spectral data format was [1200,510] and label data format was [1200,1].  The example of data usage (sklearn in Python database was used to establish the classification model) was as follows:

import numpy as np
from sklearn. model_selection import train_test_split
from sklearn. preprocessing import StandardScaler
from sklearn. neighbors import KNeighborsClassifier
from sklearn. metrics import classification_report, accuracy_score

# Load spectral data and labels
x = np.load('.../spectral.npy')[:,1:-1]
y = np.load('.../label.npy')

x_train, x_test, y_train, y_test = train_test_split(x, y, test_size=0.2, random_state=42)

# Data standardization
scaler = StandardScaler()
x_train = scaler.fit_transform(x_train)
x_test = scaler.transform(x_test)

# Train the KNN model
knn_model = KNeighborsClassifier(n_neighbors=5) 
knn_model. fit(x_train, y_train)

# Predict
y_pred = knn_model.predict(x_test)

# Print classification reports and accuracy rates
print("Classification Report:")
print(classification_report(y_test, y_pred))
print("Accuracy Score:")
print(accuracy_score(y_test, y_pred))
