    Using Python language and libraries like numpy and scipy, you can simply work wonders in data science, as shown in this task. When you give it a 2d array, the NumPy exponential function simply computes for every input value x in the input array, and returns the result in the form of a NumPy array. The numpy.exp function will take each input value, , and apply it as the exponent to the base . Before we get into the specifics of the numpy.exp function, let’s quickly review NumPy. Calculatin [...]

    The constant k is called the decay constant, disintegration constant, rate constant, or transformation constant. The exponential of a complex argument is closely related to trigonometry as shown by Euler’s formula. The argument can even be an entirely different kind of mathematical object . The example above is a special case of a situation in which a data scientist is studying how many times a rare event occurs. When $n$ is large, Special being picked on a single draw can be thought of a [...]

    We can observe that $(x – x_0)(x – x_1)ldots(x – x_n)$ is itself a factorized polynomial and that the distinct points $x_0, x_1, ldots, x_n$ are its roots. Thus the problem of reducing the relative error is equivalent to the problem of choosing roots which minimize the local maxima. As it turns out, an equi-spaced selection of points $x_0, x_1, ldots, x_n$ is rarely the optimal choice for minimizing the relative error over the entire interval. This leads us to an important dra [...]

    With the complete and self-contained Wi-Fi networking capabilities, ESP8285 can perform either as a standalone application or as the slave to a host MCU. When ESP8285 hosts the application, it promptly boots up from the flash. CPU can be run at 160 MHz, and flash can be sped up from 40 MHz to 80 MHz. With this core, the ESP8266 CPU and its Wi-Fi components can be programmed like any other Arduino device. I am considering using the ESP-01M module on a build I’m planning, though. A vertica [...]

    This allows the module to be used based on the self-contained power supply. The Arduino boards are all running with 16 MHz which means that the microprocessor can execute up to 16 million instructions per second. This may sound like a lot but when you consider that a simple setting digital pin to high can take over 50 clock cycles. As a result, he made the ESP8266 give out a signal at 60 MHz, which corresponds with the frequency of the third channel on analog TV. On the other hand, many amateu [...]

    PC uses a file system where by the program has to be loaded into RAM to execute. Your program runs out directly from ROM or Flash memory and may not even require any RAM. For the end user, it doesn’t matter all that much, but if saving money on IP licensing fees is what allows Espressif to include a more modern peripheral set for the ESP8266 price, then we’re all for it. If you do not set them in the code, they will be on the default defined pins, as shown in the figure below (this [...]
