Text to Vector , Preprocessing and Loading to mode

import nltk
from nltk.corpus import stopwords
from nltk.stem.porter import PorterStemmer
import pandas as pd
import re


nltk.download('stopwords')
port_stem = PorterStemmer()
def stemming(content):
    stemmed_content = re.sub('[^a-zA-Z]',' ',content)
    stemmed_content = stemmed_content.lower()
    stemmed_content = stemmed_content.split()
    stemmed_content = [port_stem.stem(word) for word in stemmed_content if not word in stopwords.words('english')]
    stemmed_content = ' '.join(stemmed_content)
    return stemmed_content

hupstr=input('Enter the tweet')
df1 = pd.DataFrame({'text': [hupstr]})
df1['text']  = df1['text'].apply(stemming)

from keras.models import load_model
hupmodel= load_model("hupmodel17.h5")


loaded_vectorizer = joblib.load('huptokenizer.joblib')
X2 = loaded_vectorizer.texts_to_sequences(df1['text'])
X2 = pad_sequences(X2,maxlen=337)

#X_test_transformed = loaded_vectorizer.transform(hupinput)
#X_test_dense = X_test_transformed.toarray()
hupprediction1 = hupmodel.predict_on_batch(np.stack(X2))
labelencoder = joblib.load('huplabelencoder.pkl')
huplabel1 = labelencoder.inverse_transform(np.argmax(hupprediction1, axis=1))
hupresult1 = ''.join(huplabel1)
print(hupresult1)

Print Tensorflow version

Try this

import tensorflow as tf print(tf.__version__) import keras print(keras.__version__)

How Flask file shows templates and images

Normal Flask code look like

--------------

from flask import Flask, redirect, url_for, request

app = Flask(__name__)

@app.route('/success/<name>')

def success(name):

    return 'Hi %s' % name

@app.route('/login', methods=['POST', 'GET'])

def login():

    if request.method == 'POST':

        user = request.form['name']

        return redirect(url_for('success', name=user))

    else:

        user = request.args.get('name')

        return redirect(url_for('success', name=user))

if __name__ == '__main__':

    app.run(debug=True)

--------------

If you need template page, your flask file should return the following code

return render_template('template.html', result=hupresult)

Your template.html should be saved inside templates folder

and the code template.html should look like

<!DOCTYPE html>

<head>

<title>Flask Image Example</title>

</head>

<body>

<h1>{{ result }}</h1>

</body>

</html>

The image bg.jpg should be saved inside 'static' folder

Show graph in Python for Test accuracy and Train accuracy o various ML algorithms

Hi all,

Please see the code.

import matplotlib.pyplot as plt

import numpy as np

# Example data (replace this with your actual data)

algorithms = ['KNN', 'ANN', 'Decision Tree', 'Ada Boost', 'Random forest', 'Naive Bayes', 'Log Regression']

test_accuracies = [0.85, 0.92, 0.78, 0.88, 0.95, 0.89, 0.91]

train_accuracies = [0.95, 0.97, 0.88, 0.93, 0.98, 0.92, 0.96]

# Set up bar positions

bar_width = 0.35

index = np.arange(len(algorithms))

# Create bar chart

fig, ax = plt.subplots()

bar1 = ax.bar(index, test_accuracies, bar_width, label='Test Accuracy')

bar2 = ax.bar(index + bar_width, train_accuracies, bar_width, label='Train Accuracy')

# Add labels, title, and legend

ax.set_xlabel('Machine Learning Algorithms')

ax.set_ylabel('Accuracy')

ax.set_title('Test and Train Accuracies of Machine Learning Algorithms')

ax.set_xticks(index + bar_width / 2)

ax.set_xticklabels(algorithms)

ax.legend()

# Show the plot

plt.show()

Deploy ML Model using input from user

Hi,

Please find the code

data=[]

marks=int(input("enter your marks"))

data.append(marks)

maths=int(input("enter marks for maths"))

data.append(maths)

qa=int(input("enter marks for qa"))

data.append(qa)

pg=int(input("enter marks for programing"))

data.append(pg)

ndata=[]

ndata.append(data)

result=knn.predict(ndata)

if(result==0):

  print("not placed")

else:

  print("placed")

Deploy model

Hi,

Please find the code

input1=[[60,80,90,6]]

result=knn.predict(input1)

print(result)
