TensorFlow Operations for Linear Algebra and Tensor Manipulation Introduction: Importance of Linear Algebra in Deep Learning Architectures Linear algebra is the backbone of deep learning, powering the computations that drive neural network architectures. Operations like matrix multiplication, eigenvalue decomposition, and tensor transformations are critical for tasks such as feature extraction, weight updates, and data processing. In deep learning, layers like fully connected networks rely on matrix multiplications ( tf.linalg.matmul ) to transform inputs, while operations like singular value decomposition ( tf.linalg.svd ) are used in techniques like principal component analysis for dimensionality reduction. Tensor manipulations, such as reshaping and slicing, are essential for handling multidimensional data like images or sequences, ensuring compatibility across layers. Understanding these operations in TensorFlow enables developers to build efficien...

TensorFlow: Custom Layers for Movie Preference Prediction TensorFlow: Custom Layers for Movie Preference Prediction TensorFlow, an open-source machine learning framework by Google, enables the development of custom neural network architectures through its tf.keras API. This article examines the implementation of custom layers using methods such as __init__ , build , and call , alongside auxiliary methods like get_config and compute_output_shape . To illustrate, we present a model for predicting movie preferences based on features such as duration, IMDb rating, and action scene count, offering a practical and accessible application of TensorFlow’s capabilities. 1. Custom Layers in TensorFlow Neural network layers encapsulate transformations of input data. The tf.keras.layers module provides predefined layers, including Dense for fully connected networks, Conv2D for convolutional operations, and LSTM for sequential data. Custom layers, c...

Deep Contrastive Clustering: An Unsupervised Learning Paradigm The rapid growth of high-dimensional and unlabeled data in fields such as computer vision, bioinformatics, and natural language processing has catalyzed the development of novel unsupervised learning techniques. Among them, Deep Contrastive Clustering (DCC) has emerged as a promising approach that combines the power of contrastive learning and clustering to learn semantically meaningful representations in the absence of supervision. From Representation Learning to Clustering In traditional clustering algorithms such as K-means or DBSCAN, the performance is heavily dependent on the quality of the feature representation. When operating in high-dimensional, raw input spaces—such as pixel data or word vectors—these methods often suffer from noise and irrelevant dimensions. To address this, deep learning-based methods propose to learn compact and meaningful representations before performing...
