This is the digital age, which means that all our work, business, commerce, entertainment, and about everything is done on computer machines. This also means that we have to deal with tons of files every day. So most likely, it is in your best interest to somehow decrease the size of the files you are storing. So whether you are a web publisher, who could decrease the size of the various page elements and speed up the page loading time, or a developer, who could decrease the heaviness of the software, reducing file size is general use. Even if nothing, you could make some extra room in your hard-drive for personal usage.File Optimizer for Windows PC
There are many compression tools available that have been covered extensively on our website, but recently we found FileOptimizer, an amazing compression tool with some unique features which should be shared with our readers. Over the last week, we put this software for a spin, and the results were amazing.
There are many things that FileOptimizer does, that its counterpart applications don’t do, or can’t do. FileOptimizer like many of the compressing applications provides support for an array number of file formats. So whether it is your JPEG images, or software file formats or even system library files like DLL, FileOptimizer can compress them all, except video files, which it can’t compress.
Another handy thing offered by FileOptimizer is that unlike any of its competitors, it doesn’t put files into a compressed folder in order to compress their file size, but it compresses the original file itself. Once the compression is done, it overrides the existing version with the compressed one. All these compressions are done in a lossless format. So no matter how much compression your file has went through, you can stay assured of the quality.
Depending on the kind of file it is dealing with, the software may take a bit longer than usual to compress it, so it is normal, don’t worry about it. The app is bundled with a plethora of scripts and plug-ins that are required to compress various file types, so you don’t have to worry about downloading anything by yourself.
Installation and General Use
FileOptimizer works like a portable app, which means that it doesn’t require any installation. But the file you are downloading from the web is compressed and hence needs to be extracted. The 18 MB file will decompress to around 80 MB. The software works on all Windows operating systems. The uncompressed folder contains software for both 32 bit and 64 bit CPU.
There is no valid reason why you shouldn’t be using this app. In terms of its functionality, and how much that functionality is really important, the software is a must-have. When you are commuting with things and devices where file size matters a lot, this software is nothing less than a life saver. Although you won’t find the interface and the general look of the software very adorable, the software is good as it gets.What is the best file optimizer for Windows 11/10?
There is no specific tool, which can be awarded as the best file optimizer for Windows 11/10. It depends on the type of file, configuration, etc. A file optimizer requires all the basic information about the file so that it can optimize it to get the best output. However, if you want to download a general file optimizer for Windows 11/10, you can certainly check out FileOptimizer.FileOptimizer download
You may download the File Optimizer software from its official SourceForge page.
If you’ve ever participated in data science competitions, you must be aware of the pivotal role that ensemble modeling plays. In fact, it is being said that ensemble modeling offers one of the most convincing way to build highly accurate predictive models. The availability of bagging and boosting algorithms further embellishes this method to produce awesome accuracy level.
For the rest, I am sharing some of the most commonly asked questions on ensemble modeling. If you ever wish to evaluate any person’s knowledge on ensemble, you can daringly ask these questions & check his / her knowledge. In addition, these are among the easiest questions, hence you can’t dare to get them wrong!Which are the common questions (related to Ensemble Models)?
After analyzing various data science forums, I have identified the 5 most common questions related to ensemble modeling. These questions are highly relevant to data scientists new to ensemble modeling. Here are the questions:
What is an ensemble model?
What are bagging, boosting and stacking?
Can we ensemble multiple models of same ML algorithm?
How can we identify the weights of different models?
What are the benefits of ensemble model?
Let’s discuss each question in detail.1. What is an Ensemble Model?
Let’s try to understand it by solving a classification challenge.
Problem: Set rules for classification of spam emails
Solution: We can generate various rules for classification of spam emails, let’s look at the some of them:
Have total length less than 20 words
Have only image (promotional images)
Have specific key words like “make money and grow” and “reduce your fat”
More miss spelled words in the email
Email from Analytics Vidhya domain
Email from family members or anyone from e-mail address book
Above, I’ve listed some common rules for filtering the SPAM e-mails. Do you think that all these rules individually can predict the correct class?
Most of us would say no – And that’s true! Combining these rules will provide robust prediction as compared to prediction done by individual rules. This is the principle of Ensemble Modeling. Ensemble model combines multiple ‘individual’ (diverse) models together and delivers superior prediction power.
If you want to relate this to real life, a group of people are likely to make better decisions compared to individuals, especially when group members come from diverse background. The same is true with machine learning. Basically, an ensemble is a supervised learning technique for combining multiple weak learners/ models to produce a strong learner. Ensemble model works better, when we ensemble models with low correlation.
A good example of how ensemble methods are commonly used to solve data science problems is the random forest algorithm (having multiple CART models). It performs better compared to individual CART model by classifying a new object where each tree gives “votes” for that class and the forest chooses the classification having the most votes (over all the trees in the forest). In case of regression, it takes the average of outputs of different trees.
You can also follow this article “Basics of Ensemble Learning Explained in Simple English” for more knowledge on ensemble modeling.2. What are Bagging, Boosting and Stacking?
Let’s look at each of these individually and try to understand the differences between these terms:
Bagging (Bootstrap Aggregating) is an ensemble method. First, we create random samples of the training data set (sub sets of training data set). Then, we build a classifier for each sample. Finally, results of these multiple classifiers are combined using average or majority voting. Bagging helps to reduce the variance error.
Boosting provides sequential learning of the predictors. The first predictor is learned on the whole data set, while the following are learnt on the training set based on the performance of the previous one. It starts by classifying original data set and giving equal weights to each observation. If classes are predicted incorrectly using the first learner, then it gives higher weight to the missed classified observation. Being an iterative process, it continues to add classifier learner until a limit is reached in the number of models or accuracy. Boosting has shown better predictive accuracy than bagging, but it also tends to over-fit the training data as well.
Most common example of boosting is AdaBoost and Gradient Boosting. You can also look at these articles to know more about boosting algorithms.
Stacking works in two phases. First, we use multiple base classifiers to predict the class. Second, a new learner is used to combine their predictions with the aim of reducing the generalization error.3. Can we ensemble multiple models of same ML algorithm?
Yes, we can combine multiple models of same ML algorithms, but combining multiple predictions generated by different algorithms would normally give you better predictions. It is due to the diversification or independent nature as compared to each other. For example, the predictions of a random forest, a KNN, and a Naive Bayes may be combined to create a stronger final prediction set as compared to combining three random forest model. The key to creating a powerful ensemble is model diversity. An ensemble with two techniques that are very similar in nature will perform poorly than a more diverse model set.
Example: Let’s say we have three models (A, B and C). A, B and C have prediction accuracy of 85%, 80% and 55% respectively. But A and B are found to be highly correlated where as C is meagerly correlated with both A and B. Should we combine A and B? No, we shouldn’t, because these models are highly correlated. Hence,we will not combine these two as this ensemble will not help to reduce any generalization error. I would prefer to combine A & C or B & C.
4. How can we identify the weights of different models for ensemble?
One of the most common challenge with ensemble modeling is to find optimal weights to ensemble base models. In general, we assume equal weight for all models and takes the average of predictions. But, is this the best way to deal with this challenge?
There are various methods to find the optimal weight for combining all base learners. These methods provide a fair understanding about finding the right weight. I am listing some of the methods below:
Find the collinearity between base learners and based on this table, then identify the base models to ensemble. After that look at the cross validation score (ratio of score) of identified base models to find the weight.
Find the algorithm to return the optimal weight for base learners. You can refer article Finding Optimal Weights of Ensemble Learner using Neural Network to look at the method to find optimal weight.
We can also solve the same problem using methods like:
Forward Selection of learners
Selection with Replacement
Bagging of ensemble methods
You can also look at the winning solution of Kaggle / data science competitions to understand other methods to deal with this challenge.
5. What are the benefits of ensemble model?
More stable model
There are two major benefits of Ensemble models:
The aggregate opinion of a multiple models is less noisy than other models. In finance, we called it “Diversification” a mixed portfolio of many stocks will be much less variable than just one of the stocks alone. This is also why your models will be better with ensemble of models rather than individual. One of the caution with ensemble models are over fitting although bagging takes care of it largely.End Note
In this article, we have looked at the 5 frequently asked questions on Ensemble models. While answering these questions, we have discussed about “Ensemble Models”, “Methods of Ensemble”, “Why should we ensemble diverse models?”, “Methods to identify optimal weight for ensemble” and finally “Benefits”. I would suggest you to look at the top 5 solutions of data science competitions and see their ensemble approaches to have better understanding and practice a lot. It will help you to understand what works or what doesn’t.If you like what you just read & want to continue your analytics learning, subscribe to our emails, follow us on twitter or like our facebook page.
Packet Sniffing may sound like a malicious activity at first glance, but it is actually an ethical way to analyze the network, and diagnose any network-related problems. Packet Sniffing tools are used by network technicians for such diagnostic processes. Having said this, there are an equal number of incidences where packet sniffing is used by hackers for malicious activities such as collecting passwords and spying on user traffic.
Here, we are not going to talk about packet sniffing attacks, but some free packet sniffing tools that can be effectively used to diagnose network problems and resolve the issues. Before we present you three packet sniffing tools for Windows, let’s look at how packet sniffing tools work in general.How Packet Sniffing tools work
There are different types of packet sniffers. Some packet sniffers are used only for detecting hardware-related problems. Other packet sniffing tools are actually some software apps that run on the host computers.
The packet sniffing tools intercept and log network traffic. The tools ‘view’ the network using a wireless or wired network interface. The packet sniffing tool needs to have access to this interface on its host computer. If it is a wired network, a packet sniffing tool can capture the data which totally depends on the network’s structure.
The network structure might let the packet sniffer tool view traffic on the entire network or it can let it view only a small segment of it. If it’s a wireless network, packet sniffing tools can capture one channel using the wireless interface. If the host computer has multiple wireless interfaces, then the packet sniffer can capture multiple channels.
The sniffing tool then analyzes the captured raw packet data. The analysis is converted by the sniffing tool into a readable format. This analysis is nothing but the conversation between nodes on the network. This very information is helpful for the network technicians to locate the fault.
Read: chúng tôi or Packet Monitor is the new built-in network sniffer or network diagnostic and packet monitoring tool in Windows 10.Free Packet Sniffing Tools for Windows 11/10
If you also wish to analyze your network, here are three free packet sniffing tools for Windows.1. WireShark Packet Sniffer
Wireshark is one of the popular free packet sniffing tools for Windows. This tool can give you an ability to see what’s happening on your network at a microscopic level. Some of the important features of this tool are as follows:
