Implementing PCA Transform and Inverse Transform Methods
By
–
Now define the "transform" method that transforms the input data into a lower-dimensional representation using the calculated eigenvectors. Finally the "inverse_transform" method to reconstructs the reduced data back to the original space using eigenvectors and mean.

Eigenvectors and Principal Components for Dimensionality Reduction
By
–
Eigen vectors helps in identifying the directions of highest variance in the data, which are then used to construct principal components. These principal components allows you to represent the data in a lower-dimensional while saving as much meaningful information as possible.

Implementing PCA: Fit Method with Eigenvalue Sorting
By
–
Now define the "fit" method that takes in that data and calculates the mean, normalizes the data, computes the covariance matrix, eigenvalues, and eigenvectors. Then the Eigenvectors are sorted based on eigenvalues. You may ask how, eigen vectors does dimensionality reduction?

Automated Techniques Identify Low-Quality Data in Instruction Tuning
By
–
I recently read a great article that showcases automated techniques to identify and weed out low-quality data in any instruction tuning dataset. They even put the famous Dolly-15k dataset under the microscope, and the findings are eye-opening! continue reading ….

Clean Data: The Critical Moat for LLM Performance
By
–
Clean data is the biggest MOAT, in the age of AI! LLM finetuning datasets often contain bad examples, which are harder to detect manually & become a major performance blocker. But there's a solution:
