as
tf
from
tensorflow.keras
import
layers,
models
# Load dataset
mnist
=
tf.keras.datasets.mnist
(x_train,
y_train),
(x_test,
y_test)
=
mnist.load_data()
# Build model
model
=
models.Sequential([
layers.Flatten(input_shape=(28,
28)),
layers.Dense(128,
activation='relu'),
layers.Dense(10,
activation='softmax')
])
# Compile and train
model.compile(optimizer='adam',
loss='sparse_categorical_crossentropy',
metrics=['accuracy'])
model.fit(x_train,
y_train,
epochs=5)
# Evaluate
model.evaluate(x_test,
y_test)

Sentiment Analysis with Hugging Face Transformers

1. Install Transformers: Use pip to install the Hugging Face Transformers library.
2. Load a Pre-trained Model: Use a pre-trained BERT model for sentiment analysis.
3. Tokenize Input Text: Convert text into tokens that the model can process.
4. Make Predictions: Use the model to classify text as positive, negative, or neutral.

Code Example:

from
transformers
import
pipeline
# Load sentiment analysis pipeline
classifier
=
pipeline('sentiment-analysis')
# Analyze text
result
=
classifier("I love using AI tools for my projects!")
print(result)
