Project: Improved Partitioned Learned Bloom FiltersProject Advisor: Prof. Anirban Dasgupta• Designed two novel algorithms, TurboPLBF and DiffPLBF, to efficiently construct Learned Bloom Filters, resulting in a smaller memory requirement for a Bloom Filter.• The time complexity of TurboPLBF is O(nk) compared to O(nklogn) of state-of-the-art FastPLBF++. DiffPLBF has similiar performance.• Evaluation on datasets like Malicious URLs Dataset shows the superior performance of… Show more Project: Improved Partitioned Learned Bloom FiltersProject Advisor: Prof. Anirban Dasgupta• Designed two novel algorithms, TurboPLBF and DiffPLBF, to efficiently construct Learned Bloom Filters, resulting in a smaller memory requirement for a Bloom Filter.• The time complexity of TurboPLBF is O(nk) compared to O(nklogn) of state-of-the-art FastPLBF++. DiffPLBF has similiar performance.• Evaluation on datasets like Malicious URLs Dataset shows the superior performance of TurboPLBF and DiffPLBF compared to existing LBF methods.Project: Coreset for Finite-Width Neural NetworksProject Advisor: Prof. Anirban Dasgupta• Created a novel approach to Coreset construction for approximating Neural Tangent Kernels (NTKs) using Kernel Herding with super-sampling.• Extended the Coreset to Neural Networks assuming that NTKs are a good approximation for Neural Networks.• Empirically evaluated the Coreset construction for Finite-Width Neural Networks showing promising results.Project: Hadamard-based FJLT using positional value learning in CountSketchProject Advisor: Prof. Anirban Dasgupta• Designed a novel approach to create a low-distortion embedding using the Hadamard-based Fast Johnson Lindenstrauss Transform (FJLT) by learning the positions and values in the sparse projection matrix.• Adapted a learning-based approach for CountSketch to learn the sparse projection matrix in FJLT.• Evaluation on datasets showed slightly better performance than existing state-of-the-art FJLT algorithms.
