Introduction The idea of filter groups, also known as grouped convolution, was first explored by AlexNet in 2012. This creative solution was prompted by the necessity to train the network using two Nvidia GTX 580 GPUs with 1.5GB of memory each. Challenge: Limited GPU Memory During testing, AlexNet's creators discovered it needed a little under 3GB of GPU RAM to train. Unfortunately, they couldn't train the model effectively using both GPUs because of memory limitations. The Motivation behind Filter Groups In order to solve the GPU memory problem, the authors came up with filter groups. By optimizing the model's parallelization ... Read More
Introduction Have you ever wondered how humans are able to perceive and understand the visual world with limited sensory inputs? It's a remarkable ability that allows us to compose complex visual concepts from basic elements. In the field of computer vision, scientists have been trying to mimic this compositional behavior using convolutional neural networks (CNNs). CNNs use convolution layers to extract features from images, but they have limitations when it comes to modeling visual elements with varying spatial distributions. The Problem With Convolution Convolution layers in CNNs work like pattern matching processes. They apply fixed filters to spatially aggregate input ... Read More
The linear regression method compares one or more independent variables with a dependent variable. It will allow you to see how changes in the independent variables affect the dependent variables. A comprehensive Python module, Statsmodels, provides a full range of statistical modelling capabilities, including linear regression. Here, we'll look at how to analyze the linear regression summary output provided by Statsmodels. After using Statsmodels to build a linear regression model, you can get a summary of the findings. The summary output offers insightful details regarding the model's goodness-of-fit, coefficient estimates, statistical significance, and other crucial metrics. The first section of the ... Read More
Introduction LSTM, which stands for Long Short-Term Memory, is an advanced form of recurrent neural network (RNN) specifically designed to analyze sequential data like text, speech, and time series. Unlike conventional RNNs, which struggle to capture long-term dependencies in data, LSTMs excel in understanding and predicting patterns within sequences. Conventional RNNs face a significant challenge in retaining crucial information as they process sequences over time. This limitation hampers their ability to make accurate predictions based on long-term memory. LSTM was developed to overcome this hurdle by enabling the network to store and maintain information for extended periods. Structure of an ... Read More
Introduction In recent years, deep neural networks (DNN) have made significant progress in reinforcement learning algorithms. In order to achieve desirable results, these algorithms, however, suffer from sample inefficiency. A promising approach to tackling this challenge is episodic memory-based reinforcement learning, which enables agents to grasp optimal actions rapidly. Using episodic memory to enhance agent training, Episodic Memory Deep Q-Networks (EMDQN) are a biologically inspired RL algorithm. Research shows that EMDQN significantly improves sample efficiency, thereby improving the chances of discovering effective policies. It surpasses both regular DQN and other episodic memory-based RL algorithms by achieving state-of-the-art performance on Atari ... Read More
