Mlyearning

The US website Semafor, citing eight anonymous sources familiar with the matter, reports that OpenAI’s new GPT-4 language model has one trillion parameters. Its predecessor, GPT-3, has 175 billion parameters.

OpenAI has been involved in releasing language models since 2023, when it first launched its first version of GPT followed by GPT-2 in 2023, GPT-3 in 2023 and now GPT-4 in 2023.

Language models like GPT help generate helpful content and solve users’ queries. Although one major specification that helps define the skill and generate predictions to input is the parameter.

In this article, we will talk about GPT-4 Parameters, how these parameters affect the performance of GPT-4, the number of parameters used in previous GPT models, and more.    

What are GPT Parameters?

Parameters are configuration variables that are internal to the language model. The value of these variables can be estimated or learned from the data. Parameters are essential for the language model to generate predictions. The values help define the skill of the model towards your problem by developing texts.  

Explanation of GPT-4’s Parameters

Currently, no specifications are displayed regarding the parameters used in GPT-4. Although, there were speculations that OpenAI has used around 100 Trillion parameters for GPT-4. This was later denied by OpenAI CEO Sam Altman. But since GPT-3 has 175 billion parameters added we can expect a higher number on this new language model GPT-4. 

This increases the choices of “next word” or “next sentence” based on the context input by the users. Bring more similarity to human thinking than the predecessor. Since Language models learn to optimize their parameters, which operate as configuration variables while training. By adding parameters experts have witnessed they can develop their models’ generalized intelligence. 

How many parameters in GPT 4?

Prior to GPT-4, OpenAI had released three GPT models and had been developing GPT language models for years. The first GPT launched by OpenAI in 2023 used 117 million parameters. While the second version (GPT-2) released in 2023 took a huge jump with 1.5 billion parameters. 

The current GPT-3 utilized in ChatGPT was first released in 2023 and is currently used in ChatGPT with 175 billion. However, OpenAI has refused to reveal the number of parameters used in GPT-4.

But with the development of parameters with each new model, it’s safe to say the new multimodal has more parameters than the previous language model GPT-3, with 175 billion parameters. 

How parameters affect the performance of GPT-4

The size of a model doesn’t straight affect the quality of the result produced by a language model. Likewise, the total number of parameters doesn’t necessarily influence the entire performance of GPT-4. Although, it does influence one factor of the model performance, not the overall outcome. 

For now, we are unaware of the number of parameters used in GPT-4, but if we look into GPT-3 and its parameters, there are much larger AI models with a larger number of parameters that aren’t considered the best in performance, regardless of their parameters.

Microsoft and Nvidia launched Megatron-Turning NLG, which has more than 500B parameters and is considered one of the most significant models in the market. However, MT-NLG is still considered the best in performance. 

In addition, the cost of fine-tuning increases with larger models. The current model of ChatGPT, GPT-3, was expensive to train, and if OpenAI increased the model size by 100x, it would turn out extremely expensive in computation power and training data. 

Due to this, we believe there is a low chance of OpenAI investing 100T parameters in GPT-4, considering there won’t be any drastic improvement with the number of training parameters. 

Implications of GPT-4 Parameters

The significant implication of the GPT-4 parameter is its development of natural language processing such as answering questions and understanding and analyzing the input provided with similar thinking to humans than the predecessor. Including its capabilities of text summarization, language translations, and more. 

Conclusion

Parameters play a major role in language models like GPT-4 in defining the model’s skill toward a problem via generating text. Above, we have noted all the information about parameters, including the number of parameters added in GPT-4 and previous language models.

In addition, to whether these parameters really affect the performance of GPT and what are the implications of GPT-4 parameters.

Apple Is No Longer Part Of Glassdoor’s 100 Best Places To Work Ranking

For more than a decade, Apple was considered one of the best companies to work for, as it was always at the top of Glassdoor’s 100 Best Places to Work ranking. However, Glassdoor’s 2023 ranking just came out, and surprisingly, Apple is no longer on that list.

As noted by CNBC, two major tech companies are missing from Glassdoor’s 2023 100 Best Places to Work ranking: Apple and Meta. Both companies have always been ranked in recent years, but this time something has changed. More precisely, both companies stopped performing well in Glassdoor’s ranking last year.

Apple and Meta disappear from Glassdoor’s Best Places to Work ranking

Glassdoor’s lead economist Daniel Zhao says that the lack of Apple and Meta in this year’s ranking is “pretty striking,” as both companies have never been off the list in the last decade. Apple, for example, has been in the ranking for the past 15 years, while Meta (formerly Facebook) has been on the list since 2011 and has even been number one in the past.

That’s not to say that Meta and Apple are bad places to work, they just have fallen a little bit given how competitive the list is this year.

The economist argues that Apple and Meta have been facing challenges when it comes to dealing with their employees in recent years, especially after the COVID-19 pandemic. Apple, for example, has instituted a stricter remote work policy than other Silicon Valley companies. Many key employees left the company after it required them to work in person at least three days a week.

Meta, on the other hand, has announced a mass layoff in November 2023. 13% of Meta’s employees have been laid off as the company’s revenue has been falling. Of course, this has also left the employees who continue to work there worried about possible further mass layoffs. Meta’s revenue was down 4% in the third quarter of fiscal 2023, at $27.71 billion.

9to5Mac’s Take

Even though a lot of companies are having a tough time following the COVID-19 pandemic and the ongoing war, not to mention inflation affecting the whole world, some companies are handling the situation better than others. And when it comes to employee management, it seems that Apple and Meta are having a harder time than their competitors.

Back in May 2023, Apple’s director of machine learning Ian Goodfellow left the company due to his disagreement with the in-person work policy. In 2023, multiple Apple executives also left the company due to the Apple’s back-to-the-office policy. As Apple doesn’t want to relax its remote working policies while other companies do, it’s no surprise that its employees are unhappy with the company.

Unfortunately, at the same time, Apple was accused by many employers last year of not handling reports of sexual harassment at work in the best way. If Apple remains unwilling to change the way it operates, it seems that it will continue to lose talent – and the good opinion its employees have of the company.

Is It Worth Using Low

Such platforms are innovative technologies that are used by both technical and non-technical coders. In fact, not all technical enthusiasts can prove their expertise in coding. It’s not obligatory for everyone to be experienced in generating codes if there is a need to create an application or software within a limited time. Even highly experienced software developers often look out for various alternatives to substitute traditional ways of creating apps with a minimal coding effort, whereas the notion of low-code platform and development is not new to programming specialists.

Such platforms require no preliminary introduction for experts working as part of the coding community. However, there are still a great number of coding specialists who are only on the way to getting started with low-coding application development.

Is It Worth Using This Technology?

The LCAP appeared as a reaction to the complexity and diversity of modern ways of program development. There are many famous platforms belonging to this industry segment. According to what is offered by various vendors, even ordinary users will be able to create business applications with ease in the long run.

However, it’s hard to work on such applications without the assistance of professional developers. And regrettably, modern service vendors are not created for qualified experts, while relying on them in the long-term perspective is always associated with certain risks for your business. If your company wants to use LCAP for industrial exploitation, it’s worth weighing up all pros and cons before making the final decision.

Automation of Simple Processes and Creation of Prototypes

To describe data models;

To quickly create screens with the help of widgets and samples;

To describe logic with the help of so-called microflows.

However, after going through the stage of prototype interaction of the system with the user, business logic becomes more complicated. In order to develop the project further, professional development experts are needed.

Slow Development

Any logic, be it calculations or interaction with the user, must be described in microflow as stated previously. Here, several problems arise:

It is a long process. It’s much quicker to generate codes using IDE than move or interconnect tens of blocks;

Readability is yet another important issue. Blocks look great, but as soon as the amount of information blocks grows to several dozens, it will become harder to understand the logic;

It’s used as an alternative in complicated cases. The main drawback is the absence of transparency. Here, all points of access are located in microflows. Therefore, the logic is distributed between two weakly linked environments. As a result, it becomes difficult to keep track of dependencies.

Final Word

Low-coding platforms are great for prototyping. They decrease the distance between business users and IT developers, which allows quickly getting the needed prototype and shaping the way your future system will look like. The expenses at this stage are also minimal. However, there are two major drawbacks of this technique, which include low speed and dependency on the expensive platform.

Swr Meter � What Is It How To Use It

What is SWR Meter?

SWR meter stands for Standing Wave Ratio meter, it is a measuring instrument used to measure the standing wave ratio (SWR) in a transmission line or transmitter feeder. It is also known as VSWR or ISWR. There are different types of SWR meters available, however, the working principle of all the SWR meters is the same. In this article, we will discuss the SWR meter along with its working and applications.

The SWR meter measures the degree of mismatch between a transmitter feeder and its antenna (load). This measurement is used to know the effectiveness of the impedance matching in the system.

SWR meter provides information about the amount of radio frequency (RF) energy that is reflected back to the transmitter as compared to the amount of radio frequency energy that the transmitter sent during the operation. This ratio should not be high. The ideal ratio is 1:1, which indicates that the energy is reached the destination and no energy is reflected back to the transmitter.

In the radio industry, the most common type of SWR meter used contains a dual-directional coupler. It samples a small amount of energy in one direction and a diode is provided in the circuit to rectify it before applying it to the SWR meter. However, when we use an SWR meter with a single directional coupler, then the coupler is to be rotated at 180° for sampling the power which is coming out from two different directions. The forward and reflected powers sampled by the single coupler are then used to determine the standing wave ratio. Sometimes, two single-directional couplers are provided one for each direction.

The SWR meter is used at very high frequencies, but cannot be used at low frequencies due to impractical long transmission lines.

What is the Standing Wave Ratio?

Before discussing how to use a SWR meter, it is fruitful to get the basic knowledge about standing wave ratio (SWR). The SWR may be defined as under −

The standing wave ratio (SWR) is defined as the ratio of the highest radio-frequency voltage to the minimum radio-frequency voltage through the transmission line. Here, the standing wave ratio is determined in terms of the voltage of the transmission line. Therefore, it is called the voltage standing wave ratio (VSWR).

The standing wave ratio (SWR) may also be defined as the ratio of the highest ratio-frequency current to the lowest radio-frequency current through the transmission line. Since, in this case, the SWR is identified in terms of line current, hence it is called current standing wave ratio (ISWR).

Working of SWR Meter

To understand the working of the SWR meter, we consider a directional SWR meter as shown in Figure2. The directional SWR meter is used to identify the amplitude of the transmitted wave and the amplitude of the reflected wave.

This SWR meter consists of a transmitter (Tx) terminal and an antenna (ANT) terminal which are connected through a transmission line. Here, the directional couplers are used to couple the transmission line electromagnetically. Resistors are used to terminate the transmission line at one end whereas diodes are used at another end of the line for modification. Here, resistors help in matching the characteristic impedance of the transmission line, whereas diodes assist in changing the amplitude of the signal to their corresponding DC voltage, which is then smoothed by the filter capacitors.

How to Use SWR Meter?

Using an SWR meter is quite simple; the following steps are to be followed −

Step 1 − Find a clear channel or frequency.

Step 2 − Reduce the output power from the transmitter.

Step 3 − Set the mode switch to a mode like CW, AM, FM, etc. where a constant output is produced.

Step 4 − Set the VSWR meter switch provided on the front panel to FORWARD, and rotate the CAL knob down to prevent the overloading of the meter.

Step 5 − When the transmitter is transmitting, adjust the CAL knob to obtain a full-scale reading.

Step 6 − With the SWR meter calibrated for the forward power, switch the meter to the reverse position and take the reading.

Step 7 − Stop transmitting, and check on other frequencies in the same way.

SWR Formula

The standing wave ratio (SWR) is calculated by the following expression −

Where, Γ is called the reflection coefficient, and is given by

$$mathrm{Gamma = frac{V_{rev}}{V_{fwd}}}$$

Applications of SWR Meter

The following are some important applications of the SWR meter −

SWR meter is used for the installation and tuning of transmitting antennas.

SWR meter is also used in microwave-based medical applications like microwaveelectro surgery.

In electronics, the SWR meter is used for adjusting radio transmitter and their antennas and feedlines.

Conclusion

In this article, we discussed the SWR meter, its working, formula and applications. A major limitation of the SWR meter is that it does not measure the actual impedance of the load, but only the mismatch ratio. Therefore, to measure the actual impedance, we need a radio frequency measuring device like an antenna analyzer.

Python 3.11 Is Making A Gamble In Memory Over Speed! Is It Worth It?

Python 3.11 is the first release to benefit from a project called Faster CPython!

The Python programming language releases new versions yearly, with a feature-locked beta release in the first half of the year and the final release toward the end of the year. The feature set for Python 3.11 has just been finalized, with a beta version available for testing. Developers are encouraged to try out this latest version on non-production code, both to verify that it works with your programs and to get an idea of whether your code will benefit from its performance enhancements.

Let’s look into the features in Python 3.11 Typing improvements

Python‘s type-hinting features make larger codebases easier to manage and analyze and have increased significantly with each revision since Python 3.5. Python 3.11 brings in several new type-hinting additions.

The Self type

Class methods that return self previously required obtuse and verbose annotations to be useful. typing. Self lets you annotate the return value of a class method as, simply, Self. You get useful and predictable results from your analysis tools for such methods.

CPython Optimizations

CPython is the reference implementation of the Python programming language. Written in C and Python, CPython is the default and most widely used implementation of the Python language. In version 3.11, the CPython interpreter is much more optimized and much faster than in version 3.10. CPython 3.11 is on average 1.22x faster than CPython 3.10 when measured with the performance benchmark suite, and compiled with GCC on Ubuntu Linux. Depending on your workload, the speedup could be up to 10–60% faster. In Python 3.11, the developers have mostly focused on faster startup and faster runtime as has been stated in the documentation.

Arbitrary string literal type

Previously, type annotations had no way to indicate a given variable needed to be a string literal—that is, a string defined in source code. The new typing.LiteralString annotation fixes that. Using the new annotation, linters can test for a variable is either a string defined in the source or a new string composed of only source-defined strings.

Python 3.11: I am Speed

Every new version comes with lots of improvements and the same goes with Python 3.11. One of the features (Speed) that every developer was waiting for is finally here. Since an object’s type rarely changes, the interpreter now attempts to analyze running code and replace general bytecodes with type-specific ones. For instance, binary operations (add, subtract, etc.) can be replaced with specialized versions for integers, floats, and strings.

How Python 3.11 is gaining performance?

Python function calls also require less overhead in Python 3.11. Stack frames for function call now use less memory and are more efficiently designed. Also, while recursive calls aren’t tail-optimized (which probably isn’t possible in Python, anyway), they are more efficient than in previous versions. The Python interpreter itself also starts faster, and core modules needed for the Python runtime are stored and loaded more efficiently.

Python 3.11 is the first release to benefit from a project called Faster CPython, where CPython is the standard version of the interpreter. Faster CPython is a project funded by Microsoft, whose members include Python inventor Guido van Rossum, Microsoft senior software engineer Eric Snow, and Mark Shannon – who is under contract to Microsoft as tech lead for the project.

A session scheduled for the EuroPython event to be held in Dublin in July centers on some of the changes that enable the speed-up. Shannon will describe the “adaptive specializing interpreter” in Python 3.11, which is PEP (Python Enhancement Proposal) 659. This describes a technique called specialization which, Shannon explains, “is typically done in the context of a JIT [just in time] compiler, but research shows specialization in an interpreter can boost performance significantly.”

The interpreter identifies code that can benefit from specialization and “once an instruction in a code object has executed enough times, that instruction will be “specialized” by replacing it with a new instruction that is expected to execute faster for that operation,” states the PEP. The speed-up can be “up to 50 percent.”
