In computer vision, image segmentation is the process of partitioning an image into multiple segments and associating every pixel in an input image with a class label. Semantic segmentation algorithms are used in self-driving cars. I got intrigued by this post by Lex Fridman on driving scene segmentation. I wanted to see if it works on difficult and different Indian terrain. So I have created a short video of Tawang, in Arunachal Pradesh India. The video is of duration 16...

What is Anomaly Detection In data science, anomaly detection is the identification of rare items, events or observations which raise suspicions by differing significantly from the majority of the data. In the following figure anomaly data which is a spike (shown in red color). But the same spike occurs at frequent intervals is not an anomaly. There are 3 types of Machine Learning Techniques Supervised Machine learning Unsupervised Machine Learning Semi- supervised Machine...

The question is can we identify “Boy” from “Alien”? Face Recognition addresses "who is this identity" question. This is a 1:K matching problem. We have a database of K faces we have to identify whose image is the give input image. Facenet is Tensorflow implementation of the face recognizer described in the paper "FaceNet: A Unified Embedding for Face Recognition and Clustering". FaceNet learns a neural network that encodes a face image into a vector of 128 numbers. By...

In this blog I am going to explain object detection using OpenCV library. OpenCV (Open Source Computer Vision Library: http://opencv.org) is an open-source BSD-licensed library that includes several hundreds of computer vision algorithms. It has modules like Image Processing, Video Analysis, Object Detection. OpenCV was designed for computational efficiency and with a strong focus on real-time applications. A Haar Cascade is a classifier which is used to detect the object for...

The Rotten Tomatoes movie review dataset is a corpus of movie reviews used for sentiment analysis, originally collected by Pang and Lee. This competition presented a chance to benchmark sentiment-analysis ideas on the Rotten Tomatoes dataset. We are asked to label phrases on a scale of five values: negative, somewhat negative, neutral, somewhat positive, positive. Obstacles like sentence negation, sarcasm, terseness, language ambiguity, and many others make this task very...

This blog is dedicated to my friends who want to learn AI/ML/deep learning. Explore Plant Seedling Classification dataset in Kaggle at the link https://www.kaggle.com/c/plant-seedlings-classification. It has training set images of 12 plant species seedlings organized by folder. Each image has a filename that is its unique id. The goal of the competition is to create a classifier capable of determining a plant's species from a photo. Test set we need to predict the species of...

I was searching for some pre-trained models that would read text and extract entities out of it like cities, places, time and date etc. automatically as training a model manually is time consuming and needs a lot of data to train if somebody has already done it why not reuse it. Named-entity recognition (NER) (also known as entity identification, entity chunking and entity extraction) is a sub-task of information extraction that seeks to locate and classify named entities in...

A recommender system or a recommendation system seeks to predict the "rating" or "preference" a user would give to an item. The system recommends users certain items that they think the user may be interested in, based on what they know about the user, especially when the catalogue of items is very large. Recommender systems are a useful alternative to search algorithms since they help users discover items they might not have found otherwise. Some of the examples of...
