Cupón Udemy: Redes neuronales convolucionales en Python | CNN Computer Vision con 100% de descuento por tiempo LIMITADO
Las Redes Neuronales Convolucionales son una serie de redes que fueron creadas pensando en cómo funciona el cerebro, capaces de aprender en los diferentes niveles de abstracción: en la primera capa se diferencian formas simples, colores o bordes; en la siguiente se pueden distinguir combinaciones de bordes y colores; mientras que la última capa se fija en la forma con el fin de conseguir averiguar qué es exactamente.
Para ello, los ordenadores usan filtros o lentes para ver las diferentes características: uno ve los bordes diagonales, otro los colores, etc. Funciona pasando los filtros por toda la imagen, escaneándola, para luego definirla y clasificarla.
Se pueden usar Redes Neuronales Convolucionales para que el ordenador pueda “ver”, creando sistemas “inteligentes”.
¿Cómo funciona una red neuronal convulacional?
Las redes convolucionales funcionan de manera opuesta al procesamiento de imágenes clásico basado en un algoritmo definido por humanos. Basándose en los datos de entrenamiento, la red neuronal convulacional extrae automáticamente características que luego se utilizarán para la clasificación de objetos. Las redes neuronales profundas imitan la arquitectura de la corteza visual de los mamíferos, extrayendo campos receptivos locales y conectándose a filtros.
Los campos de recepción local son un espacio separado en el que se buscan patrones. Las respuestas de los filtros se submuestrean y filtran repetidamente.
Las neuronas de la corteza visual de los mamíferos están organizadas para procesar imágenes en capas. Algunos tienen una función para reconocer características locales como bordes, líneas o formas que se cruzan. Las claves utilizadas en el análisis tienen características específicas.
La red neuronal convolucional se puede utilizar para determinar si la llave es cuadrada o redonda, qué tipo de agarre, agujero o qué forma es el perfil o color del diente.

What is covered in this course?
This course teaches you all the steps of creating a Neural network based model i.e. a Deep Learning model, to solve business problems.
Below are the course contents of this course on ANN:
Part 1 (Section 2)- Python basics
This part gets you started with Python.
This part will help you set up the python and Jupyter environment on your system and it’ll teach you how to perform some basic operations in Python. We will understand the importance of different libraries such as Numpy, Pandas & Seaborn.
Part 2 (Section 3-6) – ANN Theoretical Concepts
This part will give you a solid understanding of concepts involved in Neural Networks.
In this section you will learn about the single cells or Perceptrons and how Perceptrons are stacked to create a network architecture. Once architecture is set, we understand the Gradient descent algorithm to find the minima of a function and learn how this is used to optimize our network model.
Part 3 (Section 7-11) – Creating ANN model in Python
In this part you will learn how to create ANN models in Python.
We will start this section by creating an ANN model using Sequential API to solve a classification problem. We learn how to define network architecture, configure the model and train the model. Then we evaluate the performance of our trained model and use it to predict on new data. Lastly we learn how to save and restore models.
We also understand the importance of libraries such as Keras and TensorFlow in this part.
Part 4 (Section 12) – CNN Theoretical Concepts
In this part you will learn about convolutional and pooling layers which are the building blocks of CNN models.
In this section, we will start with the basic theory of convolutional layer, stride, filters and feature maps. We also explain how gray-scale images are different from colored images. Lastly we discuss pooling layer which bring computational efficiency in our model.
Part 5 (Section 13-14) – Creating CNN model in Python
In this part you will learn how to create CNN models in Python.
We will take the same problem of recognizing fashion objects and apply CNN model to it. We will compare the performance of our CNN model with our ANN model and notice that the accuracy increases by 9-10% when we use CNN. However, this is not the end of it. We can further improve accuracy by using certain techniques which we explore in the next part.
Part 6 (Section 15-18) – End-to-End Image Recognition project in Python
In this section we build a complete image recognition project on colored images.
We take a Kaggle image recognition competition and build CNN model to solve it. With a simple model we achieve nearly 70% accuracy on test set. Then we learn concepts like Data Augmentation and Transfer Learning which help us improve accuracy level from 70% to nearly 97% (as good as the winners of that competition).
By the end of this course, your confidence in creating a Convolutional Neural Network model in Python will soar. You’ll have a thorough understanding of how to use CNN to create predictive models and solve image recognition problems.

Below are some popular FAQs of students who want to start their Deep learning journey-
Why use Python for Deep Learning?
Understanding Python is one of the valuable skills needed for a career in Deep Learning.
Though it hasn’t always been, Python is the programming language of choice for data science. Here’s a brief history:
In 2016, it overtook R on Kaggle, the premier platform for data science competitions.
In 2017, it overtook R on KDNuggets’s annual poll of data scientists’ most used tools.
In 2018, 66% of data scientists reported using Python daily, making it the number one tool for analytics professionals.
Deep Learning experts expect this trend to continue with increasing development in the Python ecosystem. And while your journey to learn Python programming may be just beginning, it’s nice to know that employment opportunities are abundant (and growing) as well.
What is the difference between Data Mining, Machine Learning, and Deep Learning?
Put simply, machine learning and data mining use the same algorithms and techniques as data mining, except the kinds of predictions vary. While data mining discovers previously unknown patterns and knowledge, machine learning reproduces known patterns and knowledge—and further automatically applies that information to data, decision-making, and actions.
Deep learning, on the other hand, uses advanced computing power and special types of neural networks and applies them to large amounts of data to learn, understand, and identify complicated patterns. Automatic language translation and medical diagnoses are examples of deep learning.
