Hierarchical clustering limits on large datasets due to O(n²) complexity. K-means scales better, especially with subsampling or scikit-learn’s MiniBatchKMeans for faster clustering. Memory optimization via float32 reduces footprint. Distributed computing with Dask enables large-scale spatial data processing.
Optimization methods for finding thresholds. Binary search on monotone predicates, ternary search on unimodal functions. A comparison against brute force, gradient descent, simulated annealing, and genetic algorithms. Includes Python code examples for binary, ternary, and exponential search.
Python script vs. library code structure. Scripts control the process, parsing arguments with argparse and calling sys.exit. Libraries provide reusable logic, raising exceptions instead of exiting, ensuring clean separation of concerns for maintainable and testable code.
NumPy limitations in efficiency and scalability for large datasets and GPU operations highlight the advantages of tensors. TensorFlow excels in matrix multiplication, leveraging GPU power for faster computations. Automatic differentiation in tensors supports efficient gradient calculations essential for machine learning, marking a shift towards tensor-based frameworks in numerical computing.

Secure script execution in Python requires avoiding os.system to prevent shell injection vulnerabilities. Use the subprocess module for safe command execution, passing arguments as a list. Employ sys.executable to ensure the correct Python interpreter runs your scripts. Capture output and handle errors effectively with subprocess.run for robust applications.
