Allow me, if you will, to ask why you are so paranoid about this?
I can assure you that your computer's flops are lacking, mostly because of it being a laptop with mobile parts, plus by the sounds of it, no dedicated GPU, as even a mobile GPU chip would be a hefty increase. Was your old computer a laptop or desktop? Currently playing Path of Exile: Delirium! EDIT: evn was already grinding out a massive post that details it further when I wrote this I think I should point out that "FLOPS" is a theoretical calculation, and not really useful for anything other than showing changes in technology over time.
Not only that, but a CPU with a higher FLOP rating may perform worse than one with a lower rating, due to software design, core and thread efficiency, OS, and a lot of other things.

It only takes a minute to sign up. My network hasactivations and 19, parameters weights and biases. These are all 32 bit floats values, so each takes 4 bytes in memory. I don't use image augmentation, so I think the miscellaneous memory would be only related to the mini-batch size.
I'm using a mini-batch size of images. I'm using TensorFlow and I think I'm missing something. I haven't run the training yet, but I'm pretty sure based on past experiences that the memory in use will be much higher than what I've calculated. If that is the case, then I'd need more Can you help me understand the memory considerations for training my deep learning model?
Are the above considerations right? Yes, you will need to store the derivatives of the activations and of the parameters for backpropagation. Additionally, your choice of optimization may matter. These will all have different memory requirements. For example, you're going to have to store the step size cache for a momentum-based method, although that should be secondary compared to the other memory considerations you mention.
So all in all, you seem to have calculated the memory requirements for a forward pass. Andrej Karpathy mentions that the backward pass could take up to 3x the memory of the forward pass, so this might be why you see such a difference scroll down to 'Case Studies' on the website to see an example for VGGNet.
Total Memory: 4. Someone please correct me on this if I'm wrong. FYI, you already multiplied miscellaneous byso that's why I didn't multiply it by above. I would point you to this article and the corresponding video. They helped me to understand what is going on a lot better. NOTE: The memory required to use a network for predictions is far less than that required for training for two reasons:.We will learn how to implement a simple function using TensorFlow 2 and how to obtain the derivatives from it.
We will implement a Black-Scholes model for pricing a call option and then we are going to obtain the greeks. Matthias Groncki wrote a very interesting post about how to obtain the greeks of a pricing option using TensorFlow which inspired me to write this post. So, I took the same example and make some updates to use TensorFlow 2. We are going to implement the Black-Scholes formula for pricing options. In this example, we focus on the call option. Version 2 of TensorFlow has many enhancements, especially on the python API which makes it easier to write code than before.
A very cool improvement is the tf.
In previous versions of TensorFlow, we need to use tf. Now, all this process is done using tf. GradientTape which is simpler. Ok, but what if we want higher-order derivatives? The answer is easy, we only have to add a new tf. GradientTape :.
We use the well-known Black-Scholes model to estimate the price of the call. Our code can be written as follows:. To get the net present value NPV and the greeks derivatives we can write a function that wraps all the process. We have seen how to implement a TensorFlow function and how to get the derivatives from it.
Now, we are going to see another example using the Monte Carlo method. As we can see, we can get similar results with both methods. There is room for improvement, for example, we can increase the number of simulations into the Monte Carlo method. However, the results are reasonably close. Notice that the new version of TensorFlow makes the development process pretty simple which is great news for quants.

Have you read the caveats on floating point profiling? It looks like some of these may apply to your case? Yes, I've read the caveats.

Please use the latest version for TensorFlow and test again. Feel free to open a new issue if it still persists. You initialize a result matrix filled with zeros and then you add to each entry the result of the row x column multiplication. This way, one entry of the result matrix requires p multiplications, which are summed using p-1 summations. By adding it to the result matrix, you obtain one additional flop, yielding.

Right, well that's straightforward. Therefore the number of operations isOr half that, if you don't count the additions. View solution in original post.
Cappello and Dave Strenski is more of estimating the performance of the FPGA device based on the available resources and it didn't make it clear how to measure the performance in cases like mine. For eg. How many floating-point operations are applied to each element, and what is the initiation interval ie how often does it read a new value?
If you apply a single floating-point operation to a single element, which occupies cycles at MHz, then 0. After all, even a little 8-bit microcontroller doesn't take cycles to do a floating-point operation.Bhd irc
That's a much more promising number. The latency is cycles, frequency is MHz and the initiation interval is Sign In Help. Turn on suggestions.

Any idea?By Matthew Scarpino. Machine learning applications are fundamentally mathematical, and TensorFlow provides a wealth of routines for performing mathematical operations on tensors. Each routine is represented by a function of the tf package, and each function returns a tensor. When it comes to TensorFlow operations, its best to start simple. The following table lists 12 functions that perform basic math operations. The first four functions perform element-wise arithmetic.
The following code demonstrates how they work:. For example, the following two lines of code create the same tensor:. When operating on floating-point values, div and divide produce the same result. But for integer division, divide returns a floating-point result, and div returns an integer result. The following code demonstrates the difference between them:.
In contrast, the divide function performs Python-style division.

About the Book Author Matthew Scarpino has been a programmer and engineer for more than 20 years.It allows categorizing data into discrete classes by learning the relationship from a given set of labeled data.
It learns a linear relationship from the given dataset and then introduces a non-linearity in the form of the Sigmoid function. In case of Logistic regression, the hypothesis is the Sigmoid of a straight line, i.
Let us visualize the Sigmoid Function —. Output: Note that the range of the Sigmoid function is 0, 1 which means that the resultant values are in between 0 and 1.

This property of Sigmoid function makes it a really good choice of Activation Function for Binary Classification. Just like Linear Regression, we need to find the optimal values of w and b for which the cost function J is minimum. In this case, we will be using the Sigmoid Cross Entropy cost function which is given by This cost function will then be optimized using Gradient Descent.
Implementation: We will start by importing the necessary libraries. Next we will be importing the dataset. We will be using a subset of the famous Iris dataset. Now we will be One Hot Encoding the data for it to work with the algorithm. One hot encoding transforms categorical features to a format that works better with classification and regression algorithms. We will also be setting the Learning Rate and the number of Epochs.
Now we will start creating the model by defining the placeholders X and Yso that we can feed our training examples x and y into the optimizer during the training process. We will also be creating the trainable Variables W and b which can be optimized by the Gradient Descent Optimizer.
Now we will be plotting the Decision Boundary for our trained classifier. A decision boundary is a hypersurface that partitions the underlying vector space into two sets, one for each class.
