Introduction to Deep Learning
• Definition: A subset of Machine Learning
based on artificial neural networks with
representation learning.
• Focus: Learn patterns from large amounts of
data using layered neural networks.
• Inspiration: Mimics the human brain.
Types of Deep Learning
• 1. Feedforward Neural Networks (FNN)
• 2. Convolutional Neural Networks (CNN)
• 3. Recurrent Neural Networks (RNN)
• 4. Generative Adversarial Networks (GAN)
• 5. Autoencoders
Feedforward Neural Networks
(FNN)
• Simplest type of artificial neural network.
• Data flows in one direction (input → output).
• Used for basic prediction tasks.
• Example: Predicting housing prices.
Convolutional Neural Networks
(CNN)
• Designed for image data.
• Uses convolutional layers to extract spatial
features.
• Common in image recognition, computer
vision.
• Example: Handwritten digit recognition
(MNIST).
Recurrent Neural Networks (RNN)
• Designed for sequential data.
• Has feedback connections (can use previous
outputs as inputs).
• Common in NLP and time-series analysis.
• Example: Sentiment analysis, stock
forecasting.
Long Short-Term Memory (LSTM)
• A type of RNN designed to remember long-
term dependencies.
• Avoids vanishing gradient problem.
• Used in language modeling, speech
recognition.
Generative Adversarial Networks
(GAN)
• Consists of a Generator and a Discriminator.
• Generator creates fake data; Discriminator
tries to detect fake vs. real.
• Used in image generation, deepfake creation.
Autoencoders
• Unsupervised neural networks that learn to
compress and reconstruct data.
• Used for noise reduction, dimensionality
reduction.
• Example: Anomaly detection.
Deep Learning Frameworks
• Popular Tools:
• - TensorFlow
• - PyTorch
• - Keras
• - MXNet
• Provide APIs and utilities to build, train and
deploy DL models.
Applications of Deep Learning
• 1. Computer Vision: Image classification, face
recognition
• 2. Natural Language Processing: Translation,
chatbots
• 3. Healthcare: Disease detection from scans
• 4. Autonomous Vehicles: Object detection,
path planning
Steps to Apply Deep Learning
• 1. Define problem & gather data
• 2. Preprocess and split data
• 3. Choose model architecture
• 4. Train the model
• 5. Evaluate performance
• 6. Deploy and monitor
