What You Learn in Our Deep Learning Course for AI and NLP
The deep learning course offered by Online IT Guru provides a complete roadmap for mastering AI-based natural language processing. Below are the core topics covered:
1️ Foundations of Deep Learning
Before diving into NLP-specific applications, it’s essential to build a solid understanding of deep learning fundamentals.
Introduction to Artificial Neural Networks
Neural networks are inspired by the human brain and form the backbone of deep learning. A neural network consists of layers of interconnected artificial neurons, where each neuron processes inputs using weighted sums, adds a bias, and applies an activation function to produce an output.
You will learn about:
- Input layer (where data enters the network)
- Hidden layers (where intermediate computations happen)
- Output layer (where predictions are made)
Concepts of Activation Functions, Loss Functions, and Optimizers
- Activation functions add non-linearity, allowing networks to model complex relationships. You’ll study functions like:
- Sigmoid (good for probabilities)
- Tanh (zero-centered output)
- ReLU (Rectified Linear Unit) (efficient and widely used in hidden layers)
- Loss functions measure how far off predictions are from actual values. Examples include:
- Cross-entropy loss for classification
- Mean squared error (MSE) for regression
- Optimizers adjust weights to minimize the loss. You’ll explore:
- Gradient Descent
- Adam
- RMSProp
Backpropagation and Gradient Descent Algorithms
Backpropagation is the algorithm that computes the gradient of the loss function with respect to network weights. It enables the network to learn by updating weights to reduce errors. Combined with gradient descent (which moves weights in the direction of steepest loss reduction), it forms the heart of neural network training.
Overfitting, Underfitting, and Model Regularization
- Overfitting occurs when the model learns noise in the training data, performing poorly on unseen data.
- Underfitting means the model is too simple to capture the data’s patterns.
- Regularization techniques (like dropout, L2 regularization, and early stopping) help build models that generalize well.
2️ Natural Language Processing Basics
This module focuses on preparing text data for deep learning models.
Tokenization and Word Embeddings
Text data must be converted to numerical form for neural networks.
- Tokenization breaks text into smaller units (words, subwords, or characters).
- Word embeddings map tokens to dense vectors that capture semantic meaning:
- Word2Vec: learns word associations from large corpora
- GloVe: combines matrix factorization and word co-occurrence statistics
- BERT embeddings: provide context-aware representations where the meaning of a word depends on its surrounding words
These embeddings help neural networks understand and process language more effectively than traditional one-hot encoding.
Language Models for Text Prediction
Language models estimate the probability of a sequence of words. Early models like n-grams evolved into advanced deep learning models that can predict the next word in a sequence or fill in missing words, enabling applications like autocomplete and text generation.
Sequence-to-Sequence Models
Seq2Seq models transform one sequence into another, essential for tasks where input and output lengths may vary. They are widely used for:
- Machine translation
- Text summarization
- Speech-to-text systems
Seq2Seq architectures typically use an encoder to process the input and a decoder to generate the output.
3️ Deep Learning Architectures for NLP
This module dives into the specialized neural architectures that have enabled breakthroughs in NLP.
Recurrent Neural Networks (RNNs)
RNNs are designed for sequential data, where each element depends on previous elements. They maintain a hidden state that captures information about earlier inputs in a sequence, making them suitable for language modeling, speech recognition, and more.
Long Short-Term Memory (LSTM) Networks
LSTMs address the vanishing gradient problem of standard RNNs. Their unique gated architecture allows them to remember long-term dependencies, making them highly effective for tasks requiring context from earlier in the sequence, such as translation and speech transcription.
Gated Recurrent Units (GRU)
GRUs are a streamlined variant of LSTMs with fewer gates. They achieve similar performance with fewer parameters, making them faster to train and easier to deploy, especially on resource-constrained devices.
Transformer Architecture and Attention Mechanisms
Transformers represent a paradigm shift in NLP. Unlike RNNs, they process sequences in parallel and rely entirely on attention mechanisms, which allow the model to focus on relevant parts of the input sequence at each step. This architecture powers state-of-the-art models like:
- BERT (for understanding context)
- GPT (for text generation)
- T5 (for text-to-text tasks)
Attention allows models to capture dependencies regardless of distance in the sequence, enabling superior performance on complex NLP tasks.
4️ Practical Applications
This module bridges theory and practice through hands-on NLP tasks.
Sentiment Analysis Using LSTM
You’ll learn how to train LSTM models to classify text (e.g., product reviews, tweets) as positive, negative, or neutral. This application is crucial in marketing, customer service, and brand monitoring.
Machine Translation with Seq2Seq Models
Building on the encoder-decoder framework, you’ll train models to translate text from one language to another. This involves handling variable-length sequences and teaching the model to align source and target sequences effectively.
Text Classification for Spam Detection
You’ll implement deep learning models to classify emails or messages as spam or not spam. This task combines text preprocessing (e.g., tokenization, embedding) with neural networks for binary classification.
Speech Recognition Using Deep Neural Networks
Speech recognition converts audio signals into text. You’ll explore how to preprocess audio, extract features like spectrograms or MFCCs, and train neural networks (often CNN-RNN hybrids or transformers) to transcribe speech accurately.
5️ Projects and Case Studies
The course culminates in practical projects where you apply your skills to solve real-world problems.
