Bounds for the extremal eigenvalues of gain Laplacian matrices
M. Rajesh Kannan, Navish Kumar, Shivaramakrishna Pragada
A complex unit gain graph (-gain graph), is a graph where the function assigns a unit complex number to each orientation of an edge of , and its i…
Modelling the performance of delivery vehicles across urban micro-regions to accelerate the transition to cargo-bike logistics
Max Schrader, Navish Kumar, Nicolas Collignon +5
Light goods vehicles (LGV) used extensively in the last mile of delivery are one of the leading polluters in cities. Cargo-bike logistics has been put forward as a high impact cand…
Analyzing the hate and counter speech accounts on Twitter
Binny Mathew, Navish Kumar, Ravina +2
The online hate speech is proliferating with several organization and countries implementing laws to ban such harmful speech. While these restrictions might reduce the amount of su…
Optimization Guarantees for Square-Root Natural-Gradient Variational Inference
Navish Kumar, Thomas Möllenhoff, Mohammad Emtiyaz Khan +1
Variational inference with natural-gradient descent often shows fast convergence in practice, but its theoretical convergence guarantees have been challenging to establish. This is…
Urban context and delivery performance: Modelling service time for cargo bikes and vans across diverse urban environments
Maxwell Schrader, Navish Kumar, Esben Sørig +5
Light goods vehicles (LGV) used extensively in the last mile of delivery are one of the leading polluters in cities. Cargo-bike logistics and Light Electric Vehicles (LEVs) have be…
Normalized Laplacians for Gain Graphs
M. Rajesh Kannan, Navish Kumar, Shivaramakrishna Pragada
We propose the notion of normalized Laplacian matrix for a gain graphs and study its properties in detail, providing insights and counterexamples along the way. W…
