data-analysis-with-python icon data-analysis-with-python

# Data Analyis with Python Python is a great lanague for doing data analysis. Python have fantastic packages sucha s Pandas, Numpy and Matplotlib that give you a single place to analyse data and do visualization. We'll use Pandas to analyze data on video game reviews from IGN one of the most popular video review site. We are going to use Python 3.5 and google colab running jupyter notebook 4 # Import Data with Pandas our file is a csv file, comma-separated values

deep_learning_with_tensorflow_keras icon deep_learning_with_tensorflow_keras

In this tutorial series, we will learn the basics of TensorFlow, neural networks and deep learning: We will learn: What is Tensorflow and keras An intriduction to neural networks what the perception and multi-perception are real world examples: handwritten digits recognition

flask icon flask

idota icon idota

iDOTA is AI-based retinal screening application that is developed at the Douala School of AI Research Lab(DSAIRLab) to easily diagnose and prevent blindness in Cameroon. According to the WHO, the number of people of all ages visually impaired is estimated to be 285 million, of whom 39 million are blind. People 50 years and older are 82% of all blind. The major causes of visual impairment are uncorrected refractive errors (43%) and cataract (33%); the first cause of blindness is cataract (51%).

live-loss-plot-example icon live-loss-plot-example

Don't train deep learning models blindfolded! Be impatient and look at each epoch of your training! A live training loss plot in Jupyter Notebook for Keras, PyTorch and other frameworks. An open source Python package by Piotr Migdał et al. When used with Keras, Live Loss Plot is a simple callback function.

lstm_image_caption icon lstm_image_caption

Applications of LSTM - Image caption Generation. For generating captions for images, we will use a popular dataset for image captioning tasks known as Microsoft Common Objects in Context (MS-COCO). We will �rst process images from the dataset (MS-COCO) to obtain an encoding of the images with a pretrained Convolutional Neural Network (CNN), which is already good at classifying images. The CNN will take a �xed-size image as the input and output the class the image belongs to (for example, cat, dog, bus, and tree). Using this CNN, we can obtain compressed encoded vectors describing images. Then we will process the captions of the images to learn the word embeddings of the words found in captions. We can also use pretrained word vectors for this task. Finally, having obtained both the image and word encodings, we will feed them into an LSTM and train it on the images and their respective captions.

neural-network-on-mnist-dataset icon neural-network-on-mnist-dataset

Lets implement a neural network that is able to classify digits. For this task, we will be using the famous MNIST dataset made available at http://yann.lecun.com/exdb/mnist/

predicting-customer-churn icon predicting-customer-churn

A common problem across businesses in many industries is that of customer churn. Businesses often have to invest substantial amounts attracting new clients, so every time a client leaves it represents a significant investment lost. Both time and effort then need to be channelled into replacing them. Being able to predict when a client is likely to leave and offer them incentives to stay can offer huge savings to a business. This is the essence of customer churn prediction; how can we quantify if and when a customer is likely to churn?
