AI Evaluation Report

Total Score: 9/10

The agent demonstrates strong capabilities in resolving library IDs and fetching detailed documentation for various libraries and packages. It effectively retrieves relevant content, including code snippets and descriptions, for libraries such as TensorFlow, PyTorch, Pandas, and Scikit-learn. The responses are generally accurate, comprehensive, and align well with the agent's described functions. However, there was a notable issue with the NumPy task, where inaccuracies in function signatures and misleading statements about changes were present. This indicates a potential limitation in handling certain libraries or modules with precision. Overall, the agent performs well in most tasks, providing useful and clear information, but there is room for improvement in ensuring accuracy and consistency across all libraries.

     Computes the matrix norm of a matrix (or a stack of matrices).
  2. Vector Norms:

     numpy.linalg.vector_norm(x, ord=None, axis=None, keepdims=False)
     

     Computes the vector norm of a vector (or batch of vectors).
  3. Dot Products:

     numpy.vecdot(x1, x2, *, axis=None)
     

     Computes the dot product of two arrays.
  4. Outer Products:

     numpy.linalg.outer(x1, x2)

  5. Cross Products:

     numpy.linalg.cross(x1, x2, *, axis=-1)
     

     Computes the cross product of two (arrays of) 3-dimensional vectors.

  Notable Changes and Features

  • Backward Compatibility: Some functions were relocated to numpy.linalg, and their behavior was updated to support stacking and batching, affecting how they operate on multiple dimensions.

  • NamedTuples: Functions within np.linalg that previously returned standard tuples now return NamedTuples, improving code readability.

  • Performance Improvements: Functions like np.linalg.det and np.linalg.svd have been optimized for better performance, particularly when dealing with large matrices.

  • Function Enhancements: New arguments such as hermitian for numpy.linalg.pinv enable faster computations for Hermitian matrices.

  Example Usage

  Here’s an example of how to use some of the numpy.linalg functions:

  import numpy as np
  # Define a matrix
  matrix = np.array([[1, 2], [3, 4]])
  # Calculate the determinant
  det = np.linalg.det(matrix)
  # Perform Singular Value Decomposition (SVD)
  u, s, vh = np.linalg.svd(matrix)
  print(f"Determinant: {det}")
  print(f"Singular values: {s}")
