Suggested January 2024 What Is Overfitting And How To Avoid It?Introduction
In statistics, the phrase “overfitting” is used to describe a modeling error that happens when a function correlates too tightly to a certain set of data. As a result, overfitting could not be able to fit new data, which could reduce the precision of forecasting future observations.
Examining validation measures like accuracy and loss might show overfitting. The validation measures frequently increase until a point at which they level out or start to drop when the model is affected by overfitting. During an upward trend, the model looks for a good match, and once it finds one, the movement starts to turn down or stagnate.
Overfitting is a modeling issue when the model is biased because it is too closely related to the data set.
Ensembling, data augmentation, data simplification, and cross-validation are a few techniques used to avoid overfitting.How to Detect Overfitting?
Before testing the data, it is nearly hard to detect overfitting. It can benefit in addressing overfitting’s incapacity to generalize data sets, which is one of its unique features. As a result, it may be possible to split the data up into several subsets to make training and testing easier. A training set and a test set are the two main categories into which the data is split.
About 80% of the total amount of data is represented in the training set, which is also used to train the model. About 20% of the total data set is made up of the test set, which is used to assess the correctness of data that has never been utilized before. We may assess the model’s performance on each piece of data to identify overfitting when it occurs and to observe how the training process functions by segmenting the dataset.
The accuracy observed across both data sets might be used to assess performance and establish the presence or absence of overfitting. The model is obviously overfitting if it outperforms the training set and the test set.How to Prevent Overfitting? Training with More Data
Using extra data during training is one technique to avoid overfitting. With this setting, algorithms can more easily recognize patterns and reduce errors. The model will become unable to overfit all the samples as the user adds additional training data, forcing it to generalize in order to produce results.
Users should continue to gather more data in order to improve the model’s accuracy. Users should make sure that the data being utilized is accurate and relevant because this approach is pricey.Data Augmentation
Data augmentation, which is less expensive than training with extra data, is an option. If you’re unable to keep gathering new data, you might look diversified by using the data sets that are already accessible.
Every time the model processes a sample of data, data augmentation causes a minor change in the sample’s appearance. The method stops the model from learning the properties of the data sets while giving each data set the appearance of being unique to the model.
The addition of noise to the input and output data is another technique that functions similarly to data augmentation. While adding noise to the output results in more diverse data, adding noise to the input makes the model more stable without compromising data quality or privacy. However, noise addition should be used sparingly so that the amount of noise does not affect the data’s accuracy or consistency too much.Data Simplification
A model’s complex nature can cause overfitting when the model succeeds to overfit the training dataset despite having access to huge amounts of data. The model’s complexity is lowered using the data simplification technique, making the model appropriately basic to prevent overfitting.
Pruning a decision tree, lowering the number of parameters in a neural network, and applying dropout on a neutral network are a few examples of the activities that may be put into practice. The model can run more quickly and be lighter if it is simplified.Ensembling
A machine learning approach called assembling combines predictions from two or more different models. The two most common assembling techniques are bagging and boosting.
Boosting works by employing straightforward base models to raise the total complexity of the models. It instructs plenty of weak learners in sequential order so that each learner in the sequence gains knowledge from the errors of the learner before it.
Boosting brings out one strong learner by combining all the weak learners in the sequence. The alternative to boosting is the ensembling technique known as bagging. In order to maximize predictions, a large number of strong learners are trained in parallel and then combined. This is how bagging works.Conclusion
Overfitting is the inability of a computer program to generalize data sets. To avoid overfitting, it may be possible to break up the data into training and testing subsets. Users should continue to gather more data in order to improve the model’s accuracy. Data augmentation adds noise to the data to give each data set a unique appearance. Noise addition should be used sparingly so that it does not affect the data’s accuracy or consistency too much.

Our Review Pros Professional-looking interface Easy to learn Supports a wide variety of formats and devices Intuitive machine-learning component Adobe Sensei Cons Can’t purchase a perpetual license Download/installation can take a while Download Adobe Premiere free trial
If you’re even a little familiar with Adobe products, you probably expect you’ll have to pay for Adobe Premiere. And you’re right, this product doesn’t come for free. In fact, you can’t even buy a license any longer, since Adobe has adopted a subscription-based licensing type.
However, you can still choose between buying a subscription for Adobe Premiere alone or purchasing one for the entire Creative Cloud suite. Hint: the latter is more profitable, but only if you plan on using any other tool from the CC suite.How to install Adobe Premiere
For the sole purpose of simplicity, Adobe Premiere’s Creative Cloud-based installation does wonders. It allows you to download any product from the CC suite and deploy them on your PC from the same place. You only need to provide the CC tool with a valid Adobe account.
However, things are not exactly great for everyone. Several users (us included) have noticed that the download takes way longer than it should. The same goes for the installation process, which sometimes freezes, and upon restarting it, it starts all the way back from the top.How to use Adobe Premiere
If you’ve been using other Adobe products, the fact that Adobe Premiere rocks a sleek, stylish interface should be no surprise. Everything is well-organized so that you don’t have to spend a lot of time looking around for tools, and the dark theme binds it all together nicely.
Adobe Premiere might be delightful to look at, but the multitude of features might intimidate you, more so if you’re a novice. However, if you take your time to explore each of the sections, and give the features a test drive, you can familiarize yourself with the interface in no time.Produce stunning video projects with Adobe Premiere
If you didn’t figure it out by now, Adobe Premiere is a powerful video editor that you can use in a broad range of fields, such as filmography, TV, and even web content. Granted you have the footage, you can turn even regular clips into works of art.
This program includes a powerful machine learning component, called Adobe Sensei. This tool can take a huge burden off your shoulders by helping you with time-consuming tasks such as reframing videos or understanding audio types.
If that’s not enough, you can take your projects on the go with Adobe Premiere Rush. This feature acts as a cross-platform video editing tool, which will enable you to work on your video projects even from your iOS or Android devices.What is Adobe Premiere?
To wrap it up, if you’re serious about getting into video creation, Adobe Premiere can be a trustworthy ally. You can use it to turn your regular video footage into artwork, thanks to its wide variety of complex video editing tools, machine learning component, and seamless integration with other Adobe products.
Obviously, such a powerful tool doesn’t come for free, so you’ll have to purchase a subscription in order to use it. However, you can also download and use a 7-day trial if you’re not quite ready to commit to buying a subscription just yet.FAQ: Learn more about Adobe Premiere
Is Adobe Premiere free?
Not at all, you will need to purchase a subscription if you want to use Adobe Premiere at your leisure. However, there’s a 7-day trial you can download and use if you’re having a hard time deciding whether or not you want to buy a subscription.
Can you buy Adobe Premiere?
Unfortunately, you can’t buy a perpetual (lifetime) license for the latest version of Adobe Premiere. You can, however, buy a perpetual license for the CS 6 release.
What is Adobe Sensei?
Adobe Sensei is an AI-driven machine-learning component that’s included in various Adobe products. It helps you create complex projects and reduce your workload significantly by handling some of the more time-consuming operations by itself.
Monitor ghosting is a common occurrence, especially if you haven’t configured your gaming monitor correctly. Visible motion blur behind objects and monitor ghosting can be really annoying, especially during intense moments in FPS games. So, are you looking for a solution? This guide includes some of the best fixes to solve monitor ghosting or at least mitigate the problem so it becomes less annoying. With that said, let’s talk about what is monitor ghosting first, including what causes it. Then, we will go over the fixes that can alleviate the problem completely or at least reduce its effects.Monitor Ghosting: What Is It And What Causes It?
Monitor ghosting is when shadows or trailing seem to appear behind moving objects on the display. It tends to be very noticeable when the display has to show fast-paced motion, like in games or movies. Sometimes, there is monitor ghosting and motion blur happening at the same time, and it can be distracting.
What causes monitor ghosting? When the pixel response time of the monitor is too low, visual artifacts such as monitor ghosting and motion blur happen. Basically, when the pixels of a monitor cannot smoothly update themselves cleanly, as the user you may notice trailing behind objects at times. Below is an example of what monitor ghosting can look like. You can test for this on your monitor using the Blur Busters UFO tool.
In order to reduce monitor ghosting and improve visual clarity during fast-paced scenes, monitor manufacturers have been introducing new features as well as improvements to the refresh rate of monitors. As of now, 500Hz monitors have been announced, with the 360Hz refresh rate barrier being broken quite a while ago.
Sometimes, the case can be that your monitor is just not good enough to give you good response times. If that’s the issue, nothing can fix ghosting on your monitor. However, in many people’s cases, there are other factors that cause monitor ghosting. These include incorrect refresh rates set for your monitor, such as running at 60Hz when you have a 144Hz or 240Hz display. Other common factors include the use of an incorrect display profile or motion blur reduction features not being active.How to Fix Monitor Ghosting: 5 Best Methods
With the causes out of the way, we have included five solutions that may fix the monitor ghosting issue entirely, or at least circumvent it to the point where it is not distracting for you anymore.1. Set Monitor Refresh Rate To the Highest Available
If you are running Windows 10, or if you are unable to change the refresh rate to what your monitor supports (for example, having a 144Hz display but only 60Hz is available), refer to our guide on how to change the monitor refresh rate.2. Change Display Profile to Gaming Mode
Use your monitor’s buttons to access the settings, and look for a menu where you can change display profiles. For me, there were several different presets, including Gamer 1, Gamer 2, FPS, RTS, Vivid, Reader, and HDR Effect. The best one for reducing any motion blur and monitor ghosting is usually the FPS profile or Gamer.3. Change Monitor Response Time Settings 4. Enable Motion Blur Reduction Features 5. Enable VRR, GSync, or FreeSync
GSync and Freesync, along with variable refresh rate in Windows 11 (also known as VRR/ DRR), are aimed towards fixing screen tearing issues, which is different from monitor ghosting. However, the ghosting issue can still be alleviated by enabling these features.
Frequently Asked Questions
Battlefield 2042 Portal Editor: What is it and how to use it?
We walk you through how to use the Battlefield 2042 Portal Editor
The Battlefield 2042 Portal Editor is now live, allowing players the opportunity to create their own rules. You can get involved with the customs rules for Battlefield 1942, Battlefield Bad Company 2, and Battlefield 3, as part of the Battlefield 2042 experience.
How to get the Battlefield 2042 Portal Editor?
The Battlefield 2042 Portal Editor is an online web application that allows players to modify some of the oldest and popular games in the series. You can modify the games’ play, including maps from these different tiles, weapons, vehicles, and more.
Before you get round to complete editing your own custom game, you need to select the mode. The options you can edit is the Rush, Conquest, Conquest Large, Team Deathmatch and Free For All game modes. You can select which version you want to edit when you open up the Battlefield 2042 Portal Editor on the BF website (follow the link to get to it). Remember to log into the website so you can save your work for your BF games.
What can you change in the Battlefield 2042 Portal Mode?
There is quite a lot you can edit in the Battlefield 2042 Portal Editor. Firstly, you can edit the map rotation. This is a rather basic feature that is self-explanatory. Anyone who has ever rented a server on any Battlefield game will find this feels familiar. After that, the game will ask you the core game rules. This option features how many human players you want in your game and how the team distribution of those players works. You can also edit the respawn rules, reinforcement rules, and squad limit rules.
Once the core game rules are sorted, you are then directed to the gameplay modifiers. The gameplay modifiers include how the game actually plays. For example, you can increase the travel time of bullets and modify the damage you deal. You can also enable extreme weather events, which, in theory, means you can get tornados spawning on classic maps? You can also edit stationary map spawn weapons and the classic squad loadout vs Specialist options.
The soldier set offers players the option to modify how boots on the ground operate. You can enable or disable options like toggle, sprint, strafe, ADS, health regen and player health and more. These settings affect the way the game’s AI work too, modifying AI toggle, Prione, etc and more in a separate AI category. There is an option to edit Vehicles too. You can change the way vehicles spawn in, along with how long before they can respawn, including health modifiers, and a setting that determines whether you can exit a vehicle or not, which makes it very interesting for quad bike riders.
For players out there that love the Hardcore style of gameplay, you can create that if you wish. You can turn off plenty of elements on the UI, including the compass, ally identification, pinging, HUD toggle, the minimap and more.
And then, there are team modifiers. It appears you can select how the teams work. So, in theory, you can have the WW2 boys scrapping against the modern-day BF3 boys in some sort of time machine war if you wanted. Oh, and if you edit how the teams work, you can modify the weapons those teams get access to, along with the vehicles, gadgets, attachments, and characters.
Lastly, a Rules Editor option is only available on Team Death Match and FFA. It means you can essentially code your own gamemodes if you have a mega mind.
All in all, there’s a hell of a lot of options you can change. Have you got any ideas on what custom games you want? We are thinking of a giant sumo match, with knife kills only and enhanced player health to create some dirty close range deathmatches. Or, how about a sniping only hitscan battle? Select snipers only for every team and increase the bullet travel speed to max and only allow one 12 sniper scope attachment. May the best quick scoper win.
If you have a custom game that you really love, you can generate a code that allows you to share it with a friend. Simply save the game rules and then press the show code button at the bottom right of the screen.
While it might seem like Twitch and YouTube are the only platforms worth streaming on, there are dozens of others that generate quite a bit of attention among their audiences. Just as there are alternative platforms to stream on, there are alternative tools to stream your gameplay.
That’s where Steam Broadcasting comes in. This tool is a built-in feature in Steam that lets you stream your gameplay directly without any additional software. All you need to do is enable Steam broadcasting to start showing off your favorite plays and your coolest games.
Table of Contents
For the budding streamer, Steam Broadcasting is a great tool to start your channel. Here’s how you can get started.Setting Up a Steam Broadcast
There are only two requirements to broadcast on Steam, according to the service’s support page. First, you must have made at least one purchase and have access to a non-limited account. Secondly, you cannot be Community Banned. Simple enough, right?
To set up your broadcast :
To broadcast gameplay :
If it isn’t, you’ll see a notice in the top-right corner with a red circle and the current number of viewers.
If you switch away from your game to another window, Steam will display a placeholder graphic until you return to the game. The reason for this is that Steam, by default, only streams the game you are currently playing.
If you would like to change this, you can do so from the settings menu. Just keep in mind this means viewers will be able to see any information on any window you have open.Advantages Of Steam Broadcasting
There are multiple reasons why you might choose Steam Broadcasting over Twitch or YouTube. The first is that Steam has a built-in system for helping you find viewers. People interested in gameplay of the game you’re currently playing can find it easily. You’ll also be visible to the game’s community groups.
Steam has a huge audience at any given time of day, which means it’s easy to find viewers. The hard part is keeping them, and that requires a combination of humor, wit, and depending on the game, skill.
One thing to keep in mind about Steam Broadcasting, however, is the lack of customization. Unlike Twitch, Steam Broadcasting doesn’t give users the ability to create custom overlays or have custom effects on stream. You also can’t save your gameplay for upload on YouTube or another platform later.Troubleshooting Your Broadcast
If you run into trouble getting your stream to broadcast as you want it to, there are several different reasons. Steam gives a full list of suggestions, but in our experience one of the simplest solutions was to restart Steam. Shutting down the software and restarting it restored the stream without any trouble.
it opens a window of your stream and starts streaming in-game.
Whether you want to show off a new game to your friends or you want to build a name for yourself as the best player in the world, streaming is the way to go.
Steam Broadcasting makes it easy for beginners to get started with minimal equipment. In fact, you don’t even need a microphone (although it can definitely help). If your fingers are itching to show your skills, give it a shot.
Even if you’ve been on Snapchat for a while, you may not know all of its secrets. For instance, do you know that you have your very own Snapscore? This tutorial explains what a Snapchat score is, what it is good for and what you can do to increase it.What Is Snapscore?
While the “few other factors” part is a bit vague, it’s safe to assume that the more active you are at interacting with other users on the platform, the higher your score will be. The Snapscore on Snapchat is a concept that’s similar to Reddit’s Karma. It’s a way to gauge your level of engagement on the platform.
Image source: UnsplashWhat Can You Do With Your Snapscore?
You may be wondering why you should care about your Snapscore. Maybe it unlocks new options or gives you access to free goodies? Unfortunately, that’s not the case. Having a high Snapscore doesn’t translate into any bonuses. It has zero impact on you and your activities on the app.
The feature has been implemented just “for fun” to allow users to “compete” against each other. You could unlock Trophies via the Trophy Case once you reach a certain Snapscore in the past, but that feature has been discontinued. Instead, Snapchat has replaced it with “Charms”: its brand new spin on the Trophies idea. These Charms are awarded based on your interactions with your friends and are personalized.

Unfortunately, your Snapscore won’t unlock new Charms as Trophies did. Instead, you have to interact with your friends constantly to expand your Charm collection. Your Snapscore isn’t here to bring you any kind of satisfaction other than knowing that you’re one of Snapchat’s most active users.How to View Your Snapscore
If you’re curious to know what your exact Snapscore is, follow these steps to find out.
Notice the number underneath your username and Snapchat code. It’s sitting next to a tiny white ghost-like icon. That’s your Snapchat score.
Tapping the icon tells you that your Snapscore increases with each Snap you send and receive. It also lists how many Snaps you’ve sent and received.How to View Other People’s Snapscore
Now that you know how to view your own Snapscore, you may want to see how you compare to others on the social app. This is how you can view another person’s score.
Tap on your avatar in the upper-left corner of the Snapchat app to go to your profile page.
Locate the “Friends” section and tap on “My Friends” to view a list of all your friends in the app.
Tap on a friend’s avatar image, NOT on their name, to be taken to their profile.
You can see their Snapscore underneath their profile picture.
Alternatively, tap the “Chat” button at the bottom to reveal a list of all your direct messages to others, then tap on your friend’s avatar image to go to their profile again.
Note: you can only see the Snapscores of the people you’ve added to your Snapchat friend list. Of course, if your friend request hasn’t been accepted yet, you won’t get a glimpse of their Snapscore.Tips to Help Increase Your Snapscore
If you’re eager to show your friends your passion for Snapchat, we have a list of tips that could help you increase your Snapscore quickly. These methods haven’t been officially confirmed by Snapchat, except for the first, and are based on careful observation and experimentation. They’re worth trying.
Send and receive Snaps: Snapchat tells users to send as many Snaps (photos and videos alike) as possible to boost their Snapscore. A word of caution, though – sending the same Snap over and over again won’t win you extra points. Instead, you need to send unique content.
Share and view many Stories: Snapchat rewards you for sharing Stories. You could make a habit of creating a few Stories every day to notice a steady increase in your score.
Keep up the “Streak”: a streak refers to the number of days in a row that you managed to send Snaps to a specific friend. To avoid breaking a streak, you need to ensure a steady flow of content every 24 hours. Of course, this is a two-way street, so if your friend forgets to snap you and 24 hours elapse, you have to kiss your streak goodbye and start all over again. Snapchat will add an hourglass emoji beside your friend’s name in Chat to notify you to send a new snap soon.
Add many new friends: on Snapchat, you get rewarded for adding as many new friends as possible. Of course, forming such a habit may come with some consequences, especially when it comes to your privacy on Snapchat. Still, if you’re after a big Snapscore, then that probably won’t stop you from expanding your circle of friends on the app.
Watch videos in “Discover”: check the Snapchat “Discover” section to start viewing TikTok-like videos for additional points on your Snapscore.Frequently Asked Questions Can my Snapscore decrease?
No. Once your Snapscore has climbed to a certain level, it won’t go down anymore. Nothing you do will reverse your growth. Even if you take a break from the app, you’ll find the score is the same when you return. Some users have complained about experiencing sudden drops in their Snapscore, but this can most likely be attributed to a glitch or a bug.I’ve spent a lot of time on the app, but my Snapscore isn’t going up. What can I do?
If you’ve been using Snapchat quite often lately, but your Snapscore is still the same, you might not be performing activities that get you points. For example, simply chatting with someone will not increase your Snapscore. Instead, you need to send each other snaps.
On the other hand, you might have to wait a few seconds/minutes until your score is updated. Perhaps exit the app and focus on something else for a while, then come back and check your score. If it still hasn’t been updated, it might be due to an error that may or may not get resolved later. Either way, given that your Snapscore doesn’t play a vital role in your overall Snapchat experience, you can afford to wait a little bit.Can I raise my Snapscore using a third-party service?
You can only increase your Snapscore organically by being as active as possible on Snapchat. Websites and apps that claim to increase your Snapscore overnight are probably a scam, and you should stay away from them. Otherwise, you risk wasting unnecessary resources and time.
