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.

Asynchronous programming with JavaScript uses Promises and async/await for efficient code management. Chaining .then() blocks can lead to complexity, while async/await simplifies the process, improving readability. For independent requests, Promise.all() allows parallel execution, enhancing performance and ensuring error handling in concurrent operations.

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.
