My profile image shows the pitchfork bifurcation of the infinite tower function x^x^x^... at x=(1/e)^e. The inverse function x^(1/x) and its reflection are also in the plot highlighting this misbehavior in [0, (1/e)^e).

I typically try to answer questions on tensor/array manipulations, optimization, machine learning, etc. Some of the answers that I enjoyed writing:

Optimization:

• Checking intersection of tetrahedra
• Formulating different types of constraints in cvxpy
• Why is topk() differentiable?

Array manipulations:

• Transition matrix from time series data using stride tricks
• Upsampling a matrix
• Gathering values from multiple dimensions in a tensor
• Generate symmetric matrix over diagonal
• Image rotation vs. transpose
• Matrix equation computation using broadcasting

Others:

• Using close() in C
