We’ll explore intermediate clustering techniques such as hierarchical clustering, density-based clustering (DBSCAN), and Gaussian mixture models (GMM). We’ll discuss advanced clustering evaluation metrics like silhouette coefficient and adjusted Rand index. We’ll also explore methods for assessing the optimal number of clusters.
  4. Dimensionality Reduction Algorithms: Dimensionality reduction techniques reduce the number of features in a dataset while preserving important information. We’ll delve into intermediate dimensionality reduction algorithms like Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA), and t-Distributed Stochastic Neighbor Embedding (t-SNE). We’ll discuss their applications in data visualization, feature selection, and noise reduction. We’ll also explore techniques for choosing the optimal number of dimensions.
  5. Neural Networks and Deep Learning: Neural networks have revolutionized machine learning, especially with the advent of deep learning. We’ll explore intermediate-level concepts such as multi-layer perceptron (MLP), convolutional neural networks (CNNs), and recurrent neural networks (RNNs). We’ll discuss techniques for model optimization, regularization, and transfer learning. We’ll also explore advanced architectures like generative adversarial networks (GANs) and transformers.
  6. Evaluation and Performance Metrics: Accurately evaluating the performance of machine learning algorithms is crucial. We’ll delve into intermediate-level evaluation metrics such as precision, recall, F1-score, and area under the curve (AUC). We’ll explore techniques for cross-validation, stratified sampling, and model selection. We’ll discuss methods for addressing overfitting and underfitting and optimizing hyperparameters for improved model performance.
  7. Handling Imbalanced and Unstructured Data: Real-world datasets often present challenges like class imbalance and unstructured data. We’ll explore intermediate techniques for handling imbalanced datasets, including oversampling, undersampling, and ensemble methods. We’ll discuss methods for preprocessing unstructured data like text and images, including text vectorization, word embeddings, and image augmentation.
