Programación de Redes Neuronales con Python y TensorFlow

En este post les compartiré una serie de ejemplos para aprender a programar redes neuronales. Puede parecer una tarea abrumadora al principio, pero revisando los diversos modelos funcionales y un poco de abstracción, comprenderán el funcionamiento con mayor detalle.

  1. Red Neuronal Simple de un Perceptrón para Clasificación Binaria
  2. Red Neuronal Feedforward con TensorFlow.
  3. Red Neuronal Convolucional (CNN) para Clasificación de Imágenes
  4. Red Neuronal Recurrente (RNN) para Predicción de Series Temporales
  1. Red Neuronal Convolucional (CNN) para Reconocimiento de Dígitos.
  2. Red Neuronal Recurrente (RNN) con TensorFlow para Procesamiento de Lenguaje Natural.
  3. Transferencia de Aprendizaje con TensorFlow: Fine-Tuning de un Modelo Pre-entrenado.
  4. Red Neuronal LSTM para Generación de Texto
  1. Red Neuronal Generativa Adversarial (GAN)
  2. Red Neuronal Siamesa en TensorFlow.
  3. Detección de Objetos con TensorFlow y TensorFlow Object Detection API.

Con estos ejemplos sencillos, observaremos como estas redes aprenden y se adaptan, lo cual es muy diferente a la programación tradicional, donde debemos especificar reglas y algoritmos de manera explícita. En una red neuronal simple, los parámetros esenciales incluirán pesos y sesgos, funciones de activación, funciones de pérdida y ajustes. El costo de procesamiento variará según el tamaño, la complejidad de la red, el tipo de función, y la cantidad de datos principalmente. Para fines de comprensión, resultará más accesible trabajar con parámetros simples y posteriormente podrán realizar ajustes, usar funciones de activación mas eficientes, usar datos de entrenamiento más grandes, todo ello para obtener mayor precisión en los resultados.

  7. Hello Neat post Theres an issue together with your site in internet explorer would check this IE still is the marketplace chief and a large element of other folks will leave out your magnificent writing due to this problem

  8. of course like your website but you have to check the spelling on several of your posts A number of them are rife with spelling issues and I in finding it very troublesome to inform the reality on the other hand I will certainly come back again

  9. you are truly a just right webmaster The site loading speed is incredible It kind of feels that youre doing any distinctive trick In addition The contents are masterwork you have done a great activity in this matter

  10. I am not sure where youre getting your info but good topic I needs to spend some time learning much more or understanding more Thanks for magnificent info I was looking for this information for my mission

  11. Its like you read my mind You appear to know so much about this like you wrote the book in it or something I think that you can do with a few pics to drive the message home a little bit but other than that this is fantastic blog A great read Ill certainly be back

  12. I do believe all the ideas youve presented for your post They are really convincing and will certainly work Nonetheless the posts are too short for novices May just you please lengthen them a little from subsequent time Thanks for the post

  13. What i do not understood is in truth how you are not actually a lot more smartlyliked than you may be now You are very intelligent You realize therefore significantly in the case of this topic produced me individually imagine it from numerous numerous angles Its like men and women dont seem to be fascinated until it is one thing to do with Woman gaga Your own stuffs nice All the time care for it up
