The Birthday Paradox is a famous probability problem that asks: "How many people need to be in a room before there's a 50% chance that two people share the same birthday?" The counterintuitive answer is just 23 people! This paradox demonstrates how our intuition about probability can be misleading. Understanding the Mathematics The probability that two people have different birthdays is 364/365, which equals (1 - 1/365) in a non-leap year. For multiple people, the probability that all have different birthdays is: P(different) = 1 × (1-1/365) × (1-2/365) × (1-3/365) × ... Therefore, ... Read More
We can set window size using PhantomJS and Selenium webdriver in Python. PhantomJS is a headless browser that allows automated testing without displaying a GUI. To work with PhantomJS, we create a driver object of the webdriver.PhantomJS class and pass the path to the phantomjs.exe driver file as a parameter. To set the window size, we use the set_window_size method and pass the width and height dimensions as parameters. We can also retrieve the current window size using the get_window_size method. Syntax driver.set_window_size(width, height) print(driver.get_window_size()) Parameters width − The desired window width ... Read More
TensorFlow is a machine learning framework provided by Google. It is an open-source framework used with Python to implement algorithms, deep learning applications, and much more. It is used in research and for production purposes. Keras was developed as part of research for the project ONEIROS (Open-ended Neuro-Electronic Intelligent Robot Operating System). Keras is a deep learning API written in Python. It is a high-level API that provides a productive interface to help solve machine learning problems. Keras is highly scalable and comes with cross-platform abilities. This means Keras can be run on TPU or clusters of GPUs. ... Read More
Bokeh is a Python package that helps in data visualization. It is an open source project. Bokeh renders its plots using HTML and JavaScript, making it ideal for web-based dashboards and interactive applications. Bokeh can be easily used in conjunction with NumPy, Pandas, and other Python packages. It can be used to produce interactive plots, dashboards, and real-time data visualizations. Installation You can install Bokeh using pip or conda ? pip3 install bokeh Or using Anaconda ? conda install bokeh Creating Step Line Plots The step() function in ... Read More
TensorFlow is a machine learning framework provided by Google. It is an open-source framework used with Python to implement algorithms, deep learning applications, and much more. It is used for both research and production purposes. The 'tensorflow' package can be installed on Windows using the below command: pip install tensorflow The layers API is part of the Keras API. Keras is a high-level deep learning API written in Python that runs on top of TensorFlow. It provides essential abstractions and building blocks for developing machine learning solutions with a productive interface. Keras is already ... Read More
A sequential model in TensorFlow is used when you have a simple stack of layers where each layer has exactly one input and one output tensor. It's the most straightforward way to build neural networks for linear data flow. When to Use Sequential Models Sequential models are appropriate when: Each layer has exactly one input and one output tensor Layers are arranged in a linear sequence You have a simple feedforward architecture Sequential models are not appropriate when: Your model has multiple inputs or multiple outputs Layers need to be shared between ...

Keras is a high-level neural networks API that runs on top of TensorFlow. When working with deep learning models, it's common to save trained models and reload them later for inference or further training. Keras provides simple methods to save and load complete models. Prerequisites Install TensorFlow which includes Keras ? pip install tensorflow Import the required modules ? import tensorflow as tf from tensorflow import keras import numpy as np print("TensorFlow version:", tf.__version__) TensorFlow version: 2.15.0 Creating and Saving a Model First, let's create ...

Keras provides an easy way to save and load machine learning models using the HDF5 format. HDF5 (Hierarchical Data Format version 5) is a binary format that efficiently stores the complete model including architecture, weights, and training configuration. What is HDF5 Format? HDF5 is a data model and file format designed to store and organize large amounts of data. When saving Keras models in HDF5 format, it preserves: Model architecture − The structure and layers Model weights − Trained parameters Training configuration − Loss function, optimizer settings Optimizer state − Current state for resuming training ...
