Task – Feed forward Neural Networks

You will implement a feedforward artificial neural network (ANN) within Python (using Keras) for the purposes of solving a binary classification task as a mini-research project. For this network, you will be provided a dataset from the finance sector. A description of the dataset is provided in the Data Fields section of this document below.

You are expected to appropriately read in the training data, construct an ANN, train the network, and then evaluate it on the testing data.

For this you should consider aspects of the network architecture, such as how many hidden layers and nodes are required, for an ‘optimal’ solution. When constructing your network you should only consider changing this parameter, leaving others stationary, and the solver as ‘SGD’. Largely the data has already been transformed ready for the task; however, you should consider how many inputs you wish to provide to the network, both feature-wise, and number of examples.

Alongside the Python code, you will write a small report (1500 words maximum) with references (Harvard style) outlining your solution, the architecture chosen, any processing of the dataset, as well as evaluative results. For the purposes of this report, you should carefully consider experimental design, showing comparisons between various different architectures you’ve tried, using evaluative metrics to demonstrate an overall good solution to the task.

ChE 321 – Design Project 2

The Scenario:

Professor Lite’s research group has continued to study their new catalyst that increases the rate of the reaction

(1)        Toluene + Methanol   p-Xylene + Water

They quickly noticed, however, that the rate of p-xylene production was less than the rate at which toluene was consumed.  Many experiments later, they concluded that the following side reactions were also occurring on the catalyst.

(2)       p-Xylene    m-Xylene

(3)        p-Xylene + Methanol  Trimethylbenzene + Water

(4)        m-Xylene + Methanol  Trimethylbenzene + Water

with     k1 = 697 exp(-3180/T)             {mol/h-g-atm2}

k2 = 1.04×105 exp(-7200/T)     {mol/h-g-atm}

k3 = 112 exp(-1500/T)             {mol/h-g-atm2}

k4 = 335 exp(-1620/T)             {mol/h-g-atm2}

KPXY = KP = 0.070 exp(2500/T)          {1/atm}

Having heard about these results, ABC Chemicals has contracted UND to develop a catalytic reactor system for producing p-xylene using their promising new catalyst.

Process costs can be significantly reduced by avoiding high pressure and temperature conditions, and by minimizing the amount of unwanted products and unreacted feed that must be separated from the p-xylene.  Bulk chemical pricing information for feed and product compounds is listed below to help you make a preliminary economic analysis.  (Warning- these prices, as with other parameters in this project description, have been adjusted to provide a better learning experience. You should not use them for design work outside of this class)

Chemical                     Price ($/lb)

Methanol                     0.25

Toluene                       0.45

p-Xylene                     0.85

m-Xylene                    0.55

Trimethylbenzene        0.30

Your Assignment:

Use numerical simulations (Aspen Plus) to determine the best reactor system and conditions for maximizing gross margin (Total Sales of Product – Total Cost of Reactants).

Write a short project report for the engineers at ABC Chemicals documenting your findings.  It should include the following information:

  • Criteria for optimization
  • Proposed system design (reactor type, reactor + separator + ??, how connected? feed, product, recycle streams? Explain and justify your design compared to other alternatives – no calculations or simulations required, just describe qualitatively)
  • Recommended operating conditions (reactor T, P, feed flows, catalyst weight, and resulting outlet flows)
  • Discussion of the effects of operating variables (what happens when T increases/decreases and why, etc.)
  • Preliminary profitability estimate. You only need to consider the gross margin between feed and product streams. You do not need to include other operating costs, equipment costs, etc. (No, not realistic, but you’ll have opportunities to learn and practice that in Plant Design)
  • Supporting equations, calculations, figures, etc. used in your analysis (only those necessary to illustrate your findings)
  • Sample Aspen Plus input/output documentation

Aspen Plus HELP

  • Please see Aspen Plus Tutorials (Tutorial 6 for reactors, Tutorial 3 for sensitivity)
  • The catalyst density in the reactor is 1000 kg/m3.
  • This means your rate constants have the same value when expressed in units of (/g) or (/ft3).
  • Variables you will want to change are Feed Composition, Feed Temperature, Reactor Pressure and Reactor Volume, and Reactor Type (CSTR or PFR).
  • Note that for every set of T, P, and feed composition conditions there will be an optimum Reactor Volume!
  • You may/should include separators. Since the focus of this assignment is not to model the separators you should use the Sep tool and assume perfect separation.  Use 1 Sep block to remove each component.
  • Use the Sensitivity tool to vary multiple parameters.
  • A little thinking will save a lot of simulation work.

You will eventually write a response explaining what you learned from your book (at least two total pages, double-spaced). Please practice being as specific as possible in your written response. Better to offer lots of detail about one or two questions, episodes, or passages than to summarize lots of material. This is intended to be low-pressure work.

Questions to Consider as You Read:

  • How is the subject’s life similar to yours?
  • How is their life different than yours? What about their experience is unimaginable in your life?
  • What issues, struggles, or goals from the book feel familiar to you?
  • Are any strategies the subject uses to cope with these issues similar to those you use in your life? How are their strategies different from yours?

Study guide

In general, each response should be at least five sentences long and include all relevant citations. Your response should also include any relevant examples and demonstrate that you are familiar with the concept discussed in the prompt. Consult with your instructor to confirm the exact requirements.

Chapter 8:

  1. How does Smith explain that the term “sexuality” or “sexuality studies” is significant in women’s studies?
  2. In the section “gender and body politics,” Smith explains ways that governments sought to control women’s sexuality, and women’s efforts to have control over their own sexuality. In this particular section, what did you find to be most surprising?
  3. How does Smith explain the importance of various disabilities as a subfield in women’s studies?
  4. What is “embodiment?” How does Smith use this term, and what do you think she means by it?
  5. When Smith writes about “compulsory heterosexuality and the lesbian experience,” do you think this concept logically fits into the field of women’s studies?
  6. In “nature and sex” in Smith, how was science used to justify a particular agenda of acceptable sexual behavior?

Discussion

Now that we are at the conclusion of the course, let’s revisit our initial DB prompt during week 1. In that prompt, we defined the concept of “women’s studies” or “women’s realities” that we all individually had before studying this material intensively. Now, eight weeks later, let’s compare our insight now to the insight we had then. Address the following:

  1. How can we define the terms “women’s studies?” What does that mean to you now? Has this perception changed in your mind, compared to what you believed it to be in week 1? Or is it the same? Explain fully.
  2. Again, comparing your perceptions today to those you had in week 1, do you think the term “women’s studies” and any others associated with it (such as feminism, for example), has a positive or negative connotation? Give specific examples and explain fully.
  3. Based on what you learned this term, is it important that we study this particular topic in detail during our university education experience? Why or why not? Explain fully and give examples. What, if anything, can we hope to learn by studying these concepts in detail?
  4. Have your opinions about any of the items we have discussed this term changed during our course? If so, why? If not, why not? Did you learn new concepts that you were unaware of before? If so, which made the strongest impression on you?

Discussion question :

  • Unfortunately, not every child who needs treatment receives it. What do you think are some barriers to receiving treatment? In other words, what are some of the obstacles getting in the way of families hoping to pursue treatment for their child? How can we fix that?
  • One common dilemma faced by child psychologists is determining who the “client” is. Given that children are typically brought to treatment by their parents, how would you handle a child who confides in you some illicit behavior and asks you not to tell his or her parents?

Write a two paragraph summary of this week’s reading assignment.

Short discussion

When we read any argument essay, we should be aware that some information in the essay is more important than other information. In other words, some things in the essay are there in support of larger or more general arguments. We can think of the relationship between these different points as constituting a hierarchy of information. In most essays, the hierarchy breaks down in three parts.

The thesis is the main claim of an essay. The thesis is the thing that all other information is there to support. Supporting points are there to support the thesis. We can think of supporting points as offering reasons as to why the thesis is sound and logical. When supporting points are specified further, we refer to these as specific examples. Specific examples are the most specific information in an essay. For example, if you see statistics given or if you are introduced to a person in the essay who is quoted, you should think what supporting point this specific information is providing evidence of, this specific point–in turn–is there to defend the thesis.

As we read this week, take notes on the essay. Make a note every time you see a new point made, a new example given. For the Discussion this week, you will be asked to summarize the article.

Writing the summary

Summary is the first step toward argument. You have to be able to state what the terms of the argument are before you can argue whether one side or the other is right. Remember that a summary is an objective restatement of someone else’s argument. This means you should not use first person pronouns in a summary. State everything objectively. When we write about texts, the texts exist in the present tense. This means we write that the author argues, suggests, complains etc. Notice that these verbs are precise. The author is not talking, and the article does not “talk about” anything. Use present tense, precise verbs in a summary. Lastly, try to organize your summary based on the hierarchy of information. Begin with the thesis. Your first sentence should also include the author’s name and the title of the essay. From there, you should give your reader the major supporting points. Remember that you are not picking a side in a summary; you are objectively restating the author’s argument.

For Discussion 5, write a two paragraph summary of this week’s reading assignment. Remember to include the author’s name, essay title, and thesis in your first sentence. Use present tense, precise verbs throughout, and avoid the use of first person pronouns.
