Recent Advancements in GANs and Style Transfer

  The field of generative adversarial networks (GANs) and style transfer has seen significant advancements in recent years. In this blog post, we will explore the history of GANs and style transfer, the recent advancements, and where we are now. History of GANs and Style Transfer Generative adversarial networks (GANs) were first introduced in 2014 by Ian Goodfellow and his colleagues. GANs are a type of neural network that consists of two parts: a generator and a discriminator. The generator is responsible for generating new data that is similar to the training data, while the discriminator is responsible for distinguishing between the generated data and the real data. Style transfer is the process of taking the style of one image and applying it to another image. Style transfer was first introduced in 2015 by Gatys et al. They used a neural network to separate the content and style of an image and then recombine them to create a new image. Recent Advancements in GANs and Style Trans

How to Fine-Tune CLIP Model with Custom Data

The CLIP (Contrastive Language-Image Pre-training) model, developed by OpenAI, is a groundbreaking multimodal model that combines knowledge of English-language concepts with semantic knowledge of images. It consists of a text and an image encoder, which encodes textual and visual information into a multimodal embedding space. The model's architecture aims to increase the cosine similarity score of images and associated text pairs. This is achieved through a contrastive objective, which enhances the efficiency of the model by 4x times. The CLIP model's forward pass involves running the input through the text and image encoder network, normalizing the embedded features, and using them as input to compute the cosine similarity. The resulting cosine similarity is then returned as logits. CLIP's versatility is evident in its ability to perform tasks such as zero-shot image classification, image generation, abstract task execution for robots, and image captioning. It has also bee

Implementation of Q-Learning with Python

Q-learning is a popular reinforcement learning algorithm used to make decisions in an environment. It enables an agent to learn optimal actions by iteratively updating its Q-values, which represent the expected rewards for taking certain actions in specific states. Here is a step-by-step implementation of Q-learning using Python: Image by Author 1. Import the necessary libraries: import numpy as np import random 2. Define the environment: # Define the environment env = np.array([[ 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 ], [ 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 ], [ 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 ], [ 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 ], [ 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 ], [ 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 ], [ 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 ], [ 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 ], [ 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0

List of Deep Learning Algorithms you Should Know in 2023

 Deep learning is a branch of machine learning that uses artificial neural networks to perform complex calculations on large datasets. It mimics the structure and function of the human brain and trains machines by learning from examples. Deep learning is widely used by industries that deal with complex problems, such as health care, eCommerce, entertainment, and advertising. This post explores the basic types of artificial neural networks and how they work to enable deep learning algorithms. Defining Neural Networks A neural network is modeled after the human brain and has artificial neurons or nodes. These nodes are arranged in three layers: The input layer  The hidden layer(s) The output layer  The input layer feeds each node with data as inputs. The node then applies random weights, a bias, and a nonlinear function, also called an activation function, to the inputs. The activation function decides which neuron to activate. How Deep Learning Works!   Deep learning is a type of machin

Tokenization Basics

 Tokenization is a fundamental step in Natural Language Processing (NLP) that involves breaking down text into smaller parts called tokens. These tokens are then used as input for a language model. Tokenization is a crucial step in NLP because it helps machines understand human language by breaking it down into bite-sized pieces, which are easier to analyze. In this blog post, we will explore the concept of tokenization in detail, including its types, use cases, and implementation. What is Tokenization? Tokenization is the process of converting a sequence of text into smaller parts, known as tokens. These tokens can be as small as characters or as long as words. The primary reason this process matters is that it helps machines understand human language by breaking it down into bite-sized pieces, which are easier to analyze. Tokenization is akin to dissecting a sentence to understand its anatomy. Just as doctors study individual cells to understand an organ, NLP practitioners use tokeni

Building a Blog Application with Django

In this tutorial, we will build a Blog application with Django that allows users to create, edit, and delete posts. The homepage will list all blog posts, and there will be a dedicated detail page for each individual post. Django is capable of making more advanced stuff, but making a blog is an excellent first step to get a good grasp over the framework.  Pre-Requirements Django is an open-source web framework, written in Python, that follows the model-view-template architectural pattern. So Python is needed to be installed on your machine. Unfortunately, there was a significant update to Python several years ago that created a big split between Python versions, namely Python 2 the legacy version and Python 3 the version in active development. Since Python 3 is the current version in active development and addressed as the future of Python, Django rolled out a significant update, and now all the releases after Django 2.0 are only compatible with Python 3.x. Therefore this tutorial is s

On The Use of Large Language Models in Medicine

Large language models (LLMs) are artificial intelligence systems that can generate natural language texts based on a given input, such as a prompt, a keyword, or a query. LLMs have been applied to various domains, including medicine, where they can potentially assist doctors, researchers, and patients with tasks such as diagnosis, treatment, literature review, and health education. However, the use of LLMs in medicine also poses significant challenges and risks , such as: Data quality and privacy: LLMs are trained on massive amounts of text data, which may not be reliable, representative, or relevant for the medical domain. Moreover, the data may contain sensitive personal information that needs to be protected from unauthorized access or disclosure. Ethical and legal implications: LLMs may generate texts that are inaccurate, misleading, biased, or harmful for the users or the recipients. For example, an LLM may suggest a wrong diagnosis or a harmful treatment, or it may violate the p
