plotqa's Introduction

Nitesh Methani 👋

Hello, my name is Nitesh.

Currently I am working as an Applied Scientist-II at Amazon where me and my team leverage LLMs and GenAI to improve the last mile delivery experience for our customers.

I am currently working on core Geospatial use cases like Address Standardization and Validation, Parsing and Matching.

In June 2020, I graduated from IIT, Madras specialising in Deep Learning and VQA models.

I have published papers in top-tier ML conferences like WACV, AAAI, Sigspatial as well as AMLC (Amazon's internal conference).

Currently, I am focusing in the area of NLP and multi-modal models like CLIP and ViLBERT to generate business value.

How can I solve the problem ?I look forward to hearing from you

Inference in OCR is returning the wrong text.

I am trying to run inference in the PlotQA pipeline, and in the OCR stage, I am trying to transform the detection files (in the format of CLASS_LABEL CLASS_CONFIDENCE XMIN YMIN XMAX YMAX) into .csv files, using the scripts given in the pipeline. The main script is the ocr_and_sie.py. The problem is that this script returns wrong texts.

After trying to underestand the problem, I found out that the doOCR function (in ocr_and_sie.py file) is responsible for returning wrong strings to put in the CSV, although i don't know why.

Here are some examples of wrong text it returns: )ear, RVHE’IJT‘ 1‘1 and DPUIIIi'pt‘fiwtfl, and so on...

If anyone could help me with this issue I would be very thankful.

Where is the Fixed Vocabulary?

I need the fixed vocabulary to do classification, but I didn't find it.
Where is the fixed vocabulary or how to construct one?
