Soham Palande

Hi, I’m Soham. I’m currently a research engineer in J.P. Morgan’s AI Research group, where I work within the Time Series team.

Research: My interests lie broadly in interpretability for sequential data — both mechanistic and statistical — with applications in finance and healthcare. I’m particularly focused on building scalable, interpretable tools/models for multi-modal models (specifically sequential) that exploit the geometric structure of the underlying data, loss surfaces, and domain-specific mathematical constraints.

Previously: I graduated from Rutgers University-NB majoring in Computer Science and Mathematics. I was an R&D intern at L3Harris where I worked on building anomaly detection models.

Quantum Computing is at a critical juncture. Prototype quantum computers are now at a level of reliability and scale where researchers can run small scale algorithms. However, modeling errors in near-term Noisy Intermediate-Scale Quantum (NISQ) devices is necessary to harness their full potential. Existing frameworks such as IBM Qiskit are limited in their capacity to model and simulate complex noise events. We study the use of Probabilistic Graphical Models (PGMs) as a natural abstraction to efficiently simulate and model quantum circuits with no noise, uncorrelated noise (bit-flip and amplitude damping) and correlated noise using complex-valued Bayesian networks. By definition, Bayesian networks are a type of PGM that articulate conditional dependencies between events through the use of Directed Acyclic Graphs (DAGs). We study well-known quantum algorithms such as Deutsch- Jozsa and Simon’s algorithms, and transform their circuit representations into Bayesian network models by extending Python’s pgmpy library to allow for complex- valued networks. By using exact inference algorithms like Variable Elimination, we are able to create valuable inferences that can be converted into density matrices using our extension of pgmpy. We validate that our models produce correct density matrices for noisy Quantum circuits using IBM Qiskit, showing that Bayesian networks are a valid abstraction for Quantum correlated and uncorrelated noise events. The correctness of our results point to new languages and methods for representing Quantum Computations

Solar Irradiance Nowcasting Using All-Sky Imager Data

Soham Palande, and Ahmed Aziz

Aresty Research Symposium, Apr 2021

As we continue to look for ways to accelerate our transition to renewable energy, one of the fundamental obstacles to achieving this remains the unpredictable nature of wind and solar energy. Clouds moving in front of the sun and rapid changes in weather conditions cause fluctuations in the measured solar irradiance and cause serious challenges in power grid operation. In this study, we address the unpredictable nature of solar irradiance by using past irradiance measurements and leverage images captured by an All-Sky imager using a Deep Learning Framework to forecast solar irradiance over the short term. We train the model on datasets of varying sizes and show that the models significantly outperform the smart persistence model and state of the art statistical approaches using optical flow techniques.
