DEEP LEARNING COURSE VISIT NOW:https://techcadd.com/
WHAT IS DEEP LEARNING? • Subset of Machine Learning using neural networks with multiple layers • Learns complex patterns from large datasets • Ideal for tasks like image and speech recognition
DEEP LEARNING VS TRADITIONAL ML • No need for manual feature extraction • Scales well with big data • Handles unstructured data (images, text, audio
Inspired by the human brain Structure: Neurons, Layers, Weights, Biases Forward and backward propagation NEURAL NETWORK BASICS:
TYPES OF NEURAL NETWORKS: • Feedforward Neural Networks (FNN) • Convolutional Neural Networks (CNN) • Recurrent Neural Networks (RNN) • Generative Adversarial Networks (GANs)
ACTIVATION FUNCTION: • Introduce non-linearity • Common functions: • ReLU (Rectified Linear Unit) • Sigmoid • Tanh • Softmax
Loss function: Measures error (e.g., MSE, Cross-Entropy) • Optimizers: Gradient Descent, Adam • Backpropagation: Updating weights using gradients TRAINING A NEURAL NETWORK:
Convolutional Neural Networks (CNNs) • Recurrent Neural Networks (RNNs) • Generative Adversarial Networks (GANs) CNN, RNN, GAN • Designed for image and spatial data • Layers: Convolution, Pooling, Flatten, Fully Connected • Applications: Image classification, object detection • Designed for sequential data • Memory of previous inputs • Variants: LSTM, GRU • Applications: Time-series prediction, language modeling • Two networks: Generator vs. Discriminator • Used for generating realistic data (images, audio, text) • Applications: Deepfakes, image enhancement
DEEP LEARNING FRAMEWOKS • TensorFlow • Keras • PyTorch • JAX • Tool comparison and use cases
CHALLENGES IN DEEP LEARNING: • Requires large datasets and computing power • Overfitting • Interpretability • Ethical concerns (bias, misuse)
APPLICATIONS OF DEEP LEARNING: • Computer Vision: Facial recognition, medical imaging • Natural Language Processing: Chatbots, translation • Speech: Voice assistants, speech-to-text • Autonomous systems: Drones, self-driving cars
CONCLUSION: • Recap: What is DL, core networks, key use cases • Learn more through projects and practice • Suggested resources: Courses, books, datasets • Q&A
