    Study Notes

    Deep Learning

    Definition

    • A subfield of machine learning that involves the use of artificial neural networks to model and solve complex problems.
    • Inspired by the structure and function of the human brain.

    Types of Deep Learning

    • Supervised Deep Learning: Trained on labeled data to learn the mapping between input and output.
    • Unsupervised Deep Learning: Trained on unlabeled data to discover patterns and relationships.
    • Reinforcement Deep Learning: Trained on feedback in the form of rewards or penalties to learn optimal policies.

    Key Concepts

    • Artificial Neural Networks (ANNs): Composed of layers of interconnected nodes (neurons) that process and transmit information.
    • Activation Functions: Introduce non-linearity into the neural network, allowing it to learn complex relationships.
    • Backpropagation: An algorithm used to train ANNs by minimizing the error between predicted and actual outputs.

    Deep Learning Architectures

    • Convolutional Neural Networks (CNNs): Designed for image and signal processing tasks, using convolutional and pooling layers.
    • Recurrent Neural Networks (RNNs): Designed for sequential data tasks, using recurrent connections to capture temporal dependencies.
    • Long Short-Term Memory (LSTM) Networks: A type of RNN that uses memory cells to learn long-term dependencies.

    Applications of Deep Learning

    • Computer Vision: Image recognition, object detection, segmentation, and generation.
    • Natural Language Processing (NLP): Language modeling, text classification, machine translation, and chatbots.
    • Speech Recognition: Transcribing spoken language into text.

    Challenges and Limitations

    • Overfitting: When the model is too complex and performs well on training data but poorly on new data.
    • Interpretability: Difficulty in understanding why a deep learning model is making a particular prediction.
    • Adversarial Attacks: Intentionally crafted inputs designed to mislead or deceive the model.
