Docker Engine is an open-source containerization technology for building and containerizing your applications. To know more see the official site. After the successful installation of docker in your system you have to go through a few basic steps to run docker without SUDO. Step 1: Add the docker group if it doesn’t already exist sudo groupadd docker Step 2: Add the connected user “$USER” to the docker group. sudo gpasswd -a $USER docker Step 3:…
Machine learning is being used by people in various ways knowingly or unknowingly. Each time when we Google or Bing search we get the best results because they have used machine learning to rank page. The world biggest search engine giant Google offers recommendation and suggestion based on the previous user searches. In 2012, Google introduced Knowledge Graph -an algorithm used to decipher the semantic content of a search query. Facebook uses a face recognition…
You might have encountered this error while uploading database using phpmyadmin dashboard. The default size is 2MB in php.ini for “upload_max_filesize“. Change the value of upload max filesize to your desired size say 20MB. And also need to change post_max_sizeif you have changed upload_max_filesize greater or equal to upload max filesize. post_max_size must be greater or equal to upload_max_filesize. If you are ubuntu user then first locate your php.ini. Use bash command “locate php.ini” to locate…
According to Wikipedia “Mathematical morphology (MM) is a theory and technique for the analysis and processing of geometrical structures, based on set theory, lattice theory, topology, and random functions”. It is mainly applied to digital images for image processing. There are many operations of mathematical morphology but mainly used operations are dilation for increasing the image regions, erosion for shrinking the image regions and thinning for structured erosion using image pattern matching. Basic Operations of…
HoGs are a feature descriptor that has been widely and successfully used for object detection. It presents objects as a single feature vector as oppossed to a set of feature vectors where each represents a segment of the image. It’s computed by sliding window detector over an image, where a HOG descriptor is a computed for each position. Like SIFT the scale of the image is adjusted (pyramiding). HOGs are often used with SVM (Support…
Support Vector Machine is a supervised learning algorithm which can be used for both classification or regression problems. In this algorithm, data points are plotted in an n-dimension space (where n is a number of features) with the value of each feature being the value of a particular coordinate. Then, classification is done by finding hyper-plane separating between two classes. Support Vector Machine is a frontier which best segregates the two classes (hyper-plane/ line). Support…
Mask RCNN is Faster RCNN (object detection with bounding boxes) with a mask on it. It is developed by Facebook AI Research (FAIR). The output from Mask RCNN is similar to YOLO (You Only Look Once) but the implementation strategy is different. What does mask do in Mask RCNN? Mask features labels each pixel and compares each pixel with an object. Here is the link of the paper written the Facebook AI Research (FAIR) on…
“YOLO” or “You Only Look Once”, is a massive Convolutional Neural network for object detection and classification. YOLO9000 is high speed, real-time object detection algorithm that can detect on over 9000 object categories. YOLO was originally written in a framework called darknet. Darknet is an open-source deep learning framework written in C and CUDA. It is fast, easy to install, and supports both CPU and GPU computation. If you want to know more follow this…
Panda is open source, the BSD-licensed library used for data analysis in Python programming language. It is build on top of two most essential python packages numpy and matplotlib. If you have not installed panda please go through this link and play with the code. Data acquisition is the process of loading and reading data from various sources. To read any data from python panda package, we need to consider two important factor i.e. format…
A python library is a collection of functions and methods that allow you to perform lots of actions without writing any code. The libraries usually consist of built-in models providing different functionalities, which you can use directly. There are a lot of libraries offering a broad range of facilities. Below are some important python libraries used for data science. It is divided into three group i.e. Scientific Computing libraries, Visualization libraries, and Algorithmic libraries. Scientific…
