Mathematics of knapsack problems
Defined $I={1,2,…,N}$ is the set of goods. When the weight of each item $i in I$ is $w_i$ value and the upper limit of the total weight of $ v_i$ item is $W$, the following is called the knapsack problem. $$max ∑{i in I}v_iw_i s.t. ∑{i in I}v_iw_ile Wxin mathbb{N}(forall in I)$$ where $x_i$ represents the number of items to be placed in the knapsack. solution The problem is that if you perform a total search, you will try two…

【Machine Learning】 "Soft sensor" based on the LSTM network
How to create a "soft sensor" based on an LSTM network You'll need to take the following steps: Collect data and preprocess It collects data from processes and systems that you want to monitor. It is to preprocess it for use in an LSTM network. This includes data cleaning, normalization, and network understanding. Format and more. Define the architecture of the LSTM network This is the number of layers, the number of neurons in each layer and other hyperparameters to…

Why is Geidai hot and University of Tokyo not?
The Age of Concepts We have already come to a society where eccentricity, novelty, play, and concepts are required rather than basic or complex designs. Even in the IT industry, if you use the shoulders of giants or frameworks, even ordinary people can do anything. That's why I feel that the people who can produce it are more valuable. What direction are we heading? From "function" to "design" From "discussion" to "story" From "individual" to "harmony of the whole" From…
