Prathamesh Mandke

I am a 2nd year master's student in Computer Engineering at Virginia Tech focusing in Software and Machine Intelligence. I work with Prof. Anuj Karpatne in the Dept. of CS on using domain specific prior knowledge in machine learning to accelerate scientific discovery. I am broadly interested in software development, machine learning and efficient AI.

During Summer 2020, I worked as an intern at Qualcomm AI Research with the AI Model Efficieny Toolkit (AIMET) team developing visualization utilities for AIMET features. In Summer 2019, I interned at Flytbase, Inc. - an autonomous drones start-up, working on deep learning based barcode localization. Prior to that, I spent two summers interning with Siemens working on industrial autonomous systems.

I graduated with a bachelor's degree in Electronics & Telecommunication from College of Engineering, Pune in May 2019. I enjoy writing code in Python and C++. As an aside, I am an Amateur Radio enthusiast as well as an avid soccer player and athlete.

Software Engineer Intern
May 2020 - August 2020

I worked with the AI Model Efficieny Toolkit (AIMET) team at Qualcomm AI Research. I developed visualization utilities for AIMET features such as Quantization Simulation and Data Free Quantization including Cross Layer Scaling and Bias Correction. I also implemented a utility to convert AIMET’s internal model graph representation to ONNX, setting a framework for extending visualization support to additional new features.

Graduate Research Assistantship
January 2020 - May 2020
poster /

I worked on the problem of sparse view CT image reconstruction using deep Convolution Neural Networks. Modified U-Net CNN architecture with transpose convolutions and residual connection as well as reducing parameter footprint to achieve robust reconstruction performance in terms of SSIM and PSNR. Implemented Wasserstein GAN based reconstruction pipelines in PyTorch and evaluated against vanilla GANs.

Deep Knowledge Distillation: Model Compression of FaceNet CNNs for OpenCL-FPGA implementation

Bachelor's thesis, College of Engineering, Pune
December 2018 - May 2019
website /

Our work extends the idea of distillation based knowledge transfer as suggested by Hinton et al., to the regression based FaceNet model by training a MobileNet architecture from a pre-trained Inception based CNN in a student teacher setting. By training multiple models on ~1M face images from the VGG2 dataset, our work demonstrats that the student networks show similar and even marginally better performance than the teacher on the LFW face verification task, thus, corroborating the theory behind knowledge transfer. We also benchmarked the performance of the Inception (teacher) and the MobileNet (student) networks on the DE10 Nano SoC FPGA using OpenCL.

Clustering Large Scale Text Corpora for Efficient Information Retrieval

Virginia Tech
August 2019 - December 2019
website / code /

Vectorized 2 large text corpora viz., the ETD corpus with ~33k documents and the Tobacco Settlement articles corpus with ~1M documents using Doc2Vec - a neural network based algorithm by Quoc Le and Tomas Mikolov. Implemented K-Means clustering, Agglomerative clustering, DBSCAN and Birch on the document vectors, thereby benchmarking them based on such metrics as the Calinski-Harasbasz Index, the Davies-Bouldin score and the Silhoutte score. Also, implemented robust cross-validation for cluster size. All experiments conducted on the Kubernetes cluster in the Dept. of CS at VT using docker for containerization and the Ceph file system.

IEEE: Human Posture Recognition using Artificial Neural Networks

H. Kale, P. Mandke, H. Mahajan, V. Deshpande, 2018 IEEE 8th International Advance Computing Conference, Greater Noida, India,2018, pp. 272-278.
January 2018 - May 2018
paper / dataset /

This work proposes the design of an embedded human posture recognition system using Artificial Neural Networks as the classifiers. We present the design, build a prototype and demonstrate the results of experimentation with human subjects. The MEMS IMU MPU-6050 accelerometer sensor is interfaced to the ESP-8266 based NodeMCU to wirelessly transmit the data to a central Raspberry-Pi server using HTTP over TCP/IP for real-time inference. Our design deploys two sensor modules, one each on the thigh and chest of the human subject. We perform experimentation by training an artificial neural network by building our own custom dataset of 44,800 points across 6 postures.

Lempel-Ziv-Welch Text File Compression - A Python Package

College of Engineering, Pune
March 2018 - July 2018
code /

I worked with Prof. P. P. Bartakke to build this python package for utf-8 text file compression based on the Lempel-Ziv-Welch universal coding algorithm. Achieves O(logN) phrase look-up complexity using the trie data structure for storing codebook entries. As an extension to our work, we studied the variation of the compression ratio as a fucntion of the underlying file distribution. By generating synthetic files with Poisson, Uniform, Gaussian and Exponential distributions we demonstrated a strong correlation between the file distribution and the compression ratio.
