Lab 1: Basic TensorFlow Computation Graph

This example demonstrates how to define and execute a simple computation graph in TensorFlow using the @tf.function decorator, which converts a Python function into a high-performance TensorFlow graph.

import tensorflow as tf

# Define a simple computation graph
@tf.function  # Converts Python function into a TensorFlow graph
def my_graph(x, y):
  return x * y + 5  # Simple equation: (x * y) + 5

# Create TensorFlow constants (nodes)
x = tf.constant(3.0)
y = tf.constant(4.0)

# Run the computation graph
result = my_graph(x, y)

# Print the result
# Convert tensor to a NumPy array to see the value
print(f"Result of (x * y) + 5: {result.numpy()}")

Cheat Sheets: Definition, Academic Use, and Technical Reference

What is a Cheat Sheet? Definition and Terminology

A cheat sheet or crib sheet is a concise set of notes used for quick reference. The term may also be rendered as cheatsheet.

Academic Use and Exam Preparation

Cheat sheets are so named because they may be used by students without the instructor's knowledge to cheat on a test. However, in many educational settings, particularly high school or undergraduate studies, rote memorization is often less important than basic education or intense graduate studies. Therefore, students may be permitted to consult their own notes during the exam, which is not considered cheating.

The act of preparing a so-called cheat sheet is also an educational exercise. For this reason, students are typically only allowed... Continue reading "Cheat Sheets: Definition, Academic Use, and Technical Reference" »

What is Lorem Ipsum?

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Programming Concepts: Constants, Constructs, and Operators

Classified in Computers

Written on in with a size of 1.72 KB

Programming Fundamentals

What is a Constant?

A constant is a data value that remains unchanged during the execution of a program.

Three Programming Constructs

The three fundamental programming constructs are: selection, iteration, and sequence.

Logical Operators

One example of a logical operator is AND.

  • Operator: and
  • Description: Logical AND: True if both operands are true.
  • Syntax: x and y

Functions vs. Procedures

Difference: A function is typically used to calculate a value from a given input, while a procedure is a set of commands executed in a specific order.

Similarity: Functions must return a value, but in stored procedures, it is optional. Procedures can return zero or multiple values. Functions usually have only input parameters, whereas procedures... Continue reading "Programming Concepts: Constants, Constructs, and Operators" »
